I am Your Dog’s Gracilis Muscle

Dog jumping

You might have never heard about a dog’s gracilis muscle, but this muscle is one that certain dog owners may never forget about once their dog develops problems with it. Just as in humans, a dog’s body is made of several muscles which allow force and motion. It is thanks to your dog’s muscles after all that your dog can maintain and change posture, move about, and ultimately live his life, considering that even the heart is muscle.

The gracilis is an important muscle of your dog’s hind leg that can be in certain circumstances prone to injury. So today, let’s discover more about your dog’s gracilis muscle, the role it plays and potential problems this body part may be prone to.

Introducing Your Dog’s Gracilis Muscle

Hello, it’s your dog’s gracilis muscle talking! My name derives from the ancient Latin word “gracilis ” meaning slender, thin. And if you take a look at me by taking a peek at  the picture on the left, you may have a clear idea why I am called this way.

I am found in your dog’s hind limb, and more specifically, the inner surface of the thigh. I am categorized as a skeletal muscle meaning that I am a “voluntary muscle” anchored to bone and used to allow locomotion. 

I Create Motion

Yes, as mentioned, as many of your dog’s other muscles, I am responsible for allowing motion. What do I do exactly? I allow adduction of the thigh, that is, movement of  the limb towards the body, extension of the hip and extension of the hock. Quite a lot, for a thin muscle like me, huh?

When Things Go Wrong

The most common type of injury affecting me, is a muscle contracture, also known as fibrotic myopathy. What exactly is a muscle contracture? The term may sound familiar but it’s different from a muscle contraction.

While a muscle contraction is the normal process of a muscle temporarily shortening when it’s being worked, a contracture is a pathological, abnormal shortening of muscle tissue, causing it to become resistant to stretching which can lead to long-term disability.

You see, when I am subjected to injury, scar tissue, under the form of fibrous connective tissue may form. However, sometimes, I may be almost entirely or completely replaced with fibrous connective tissue. Now scar tissue is less flexible than muscle fibers and therefore it leads to shortening which may limit my ability to allow a dog to to flex or extend the leg. Dogs affected by a gracilis contracture may therefore show signs of pain in the acute phases, lameness, a decreased range of motion and a characteristic gait.

The signature gait is characterized by the affected leg being raised with a jerky motion, with the hock flexed and rotated laterally, and a shortened stride due to the dog being unable to fully extend the ankle, knee, and hip joints. A video though is worth 1,000 words, so to give an idea of what happens to me when I am injured, you are better off watching it to see the gait.

In the greyhound racing business,  injury caused by me is often referred to as “dropped muscle” because affected dogs may develop a bulging area in the inner area of the dog’s thigh. Generally, this type of injury is most commonly seen in German Shepherds and Shepherd related breeds, but it can be present in many other large breed dogs with an active, working lifestyle.

 “Although fibrous scar tissue provides tensile strength and plays a part in normal muscle healing, excessive scar tissue impedes muscle fiber regeneration and interferes with muscle contraction and relaxation, resulting in varying degrees of mechanical lameness.”~ Sherman O. Canapp

Did you know? Mechanical lameness refers to lameness that is not caused by pain but rather is triggered by a physical abnormality, such as presence of scar tissue, that prevents the normal motion of the leg.

As seen, I am an important structure that requires attention. If your dog is engaged in sporting events, it may help me, along with my other fellow muscles, if you could ensure proper conditioning and allow appropriate warm-ups and cool-downs. Passive stretching and massage before events is also helpful! Consult with your vet or a vet specializing in canine sports for the best ways to take care of me and prevent problems. I hope this has helped you understand me better,

Best regards,

What’s Up With Dogs Shredding Paper?

Dog hiding under blankets

Whether it’s a roll of toilet paper or a pile of junk mail, many dogs enjoy shredding paper just about as much as playing with a toy, what gives? For a good reason, several dog owners have granted their dogs the nickname of “Shreddy” or “Confetti” due to their abilities to shred things into pieces. Sure, watching a dog shred paper into pieces can be quite fun, but it might not be too much if it involves your homework, your daily newspaper or some important documents and you must then pick up all those minute pieces! Of course, you can train your dog to help you pick them up, but if you don’t make the activity rewarding enough, most dogs will just abandon the room and leave you on your own cleaning up the mess.

A Matter of Sensory Enrichment

Dogs in general, but in particular, puppies and young dogs, are often on the lookout for novelties or anything that provides them with some level of sensory enrichment. Just the mere sensation of holding paper in their mouth may feel rewarding, but there’s often more to that.

Mail can be interesting because it’s covered in a variety of scents and bubble mailers may be fun to pop and then shred into pieces. Paper rolled up in a ball stolen from the waste basket is fun to pat, mouth and chase and toilet paper roll is fun to unroll and then shred.

Tearing paper into pieces fulfills a dog’s ancestral need to eviscerate and tear apart prey animals. Even though dogs are domesticated, they have inbuilt motor patterns reminiscent of the old days when they were hunting and paper may fulfill a dog’s needs to grab, bite, shake and dissect.

A box of tissue paper may therefore be fun to “tug” with and grab to empty it of its contents, which obviously will be then mercilessly torn apart. Paper dishes are fun to hold on to and “kill” with several head shakes. All of these paper-related products are extremely inviting to your dog, unveiling the the “tissue paper predator” in your dog who can’t help himself but jump into the whole fun and rewarding activity of shredding paper to pieces.

Did you know? According to Forrest Wickman the popular excuse “my dog ate my homework” possibly originates from as early as 1905, when a clergyman pulled his clerk aside after a service to ask him whether his sermon seemed long enough. The clerk reassured  him that it was fine and of the right length, when the priest relieved said “I am very glad to hear you say that because my dog got a hold of my sermon and ate some of the last pages.” Soon, the saying got quite popular and become the infamous excuse used by countless students when they failed to turn in their homework.

A Word About Boredom

As seen, tissue paper, toilet rolls, newspapers and paper dishes are appealing to dogs, but they may be particularly appealing to bored dogs in search of something to do to keep occupied. And for those attention-seeking dogs, picking up some paper from a wastebasket or stealing a roll of toilet paper may be a way to grab their owner’s attention when they are feeling bored and socially deprived.

A word of caution though is needed here. Many people are aware of the popular adage “a tired dog, is a good dog.” This saying is often misinterpreted, giving people  the misled notion that “If I exercise my dog enough, he’ll be good for the rest of the day.”

No, exercise will not automatically grant your dog a halo over his head and magically transform him into a dog who says “no, I won’t shred this tissue paper, cause all my energy has been drained.”

Just as you would enjoy doing crossword puzzles or read a book after going to the gym, your dog is entitled to still feel like shredding paper after going for a hike. Shredding paper can actually be a relaxing way to end the day and most dogs do it when they are comfortably lying down. Sure, exercise may cause your dog to calm down and want to sleep more, but don’t expect exercise to cause him to become apathetic and disinterested in his surroundings, that’s a depressed dog or a sick dog, not a tired dog!

Warning: while your dog may just have fun shredding paper, consider that if the paper has remnants of something tasty on it, your dog may feel compelled to ingest it. There are countless stories of dogs ingesting napkins with pizza sauce or cupcake wrappers.

Creating a Nest


Owners of pregnant dogs may witness their dogs shredding paper and other objects to pieces as whelping day gets closer. This behavior stems from instinct; mother dog is simply replicating what she would have done out of a domestic setting, which is building a maternal den.

Basically, when getting ready to give birth, a dog’s ancestors would have dug up a place to raise their puppies so they were safe, warm and dry. Puppies, being altricial, are born in a pretty much helpless state; basically, they are deaf, blind and unable to regulate their temperatures, so the use of a den was a good choice to up the pups’ chances for survival.

Even as today, mother dogs still retain the instinct to build a den. Owners of pregnant dogs often observe how, as the birthing day nears, their dogs are prone to start digging on couches, sofas and in closets and shredding cloth or pieces of paper for the purpose of building a maternal den.

These behaviors are referred to as “nesting behaviors” and they are reminiscent of when the puppies were kept safe in a den until they reached about 10 to 12 weeks of age. Past this age, the pups would then start using their dens less and less and rely more on special rendezvous areas that can be compared to open-air kindergartens.

Did you know? The instinct of creating a nest, isn’t necessarily a sign of pregnancy. False pregnancy in dogs may also evoke nesting behaviors in intact dogs who recently went into heat but didn’t get pregnant.

Tips to Stop Dogs From Eating Paper


Help, my dog shreds paper and eats it, what should I do? Some dogs unfortunately take shredding paper a step further and end up also eating it. Obviously, this is not good as it may cause digestive upset and even lead to a blockage, which can lead to costly surgery.

The best option to stop a dog from eating paper is to simply shut the bathroom door, invest in wastebaskets with lids and keep tissues out of reach, in places that even a jumping dog can’t reach. Think of your puppy or dog as a toddler who is crawling around and at risk for getting into things he shouldn’t have.

Providing interactive toys that can be stuffed with treats can help provide mental stimulation; however, just because your dog has a fun chew toy, doesn’t mean that he’ll ignore a tissue paper that just fell on the floor!

Studies have shown that dogs are attracted to novelty and even when presented with new toys, their interest tends to wane after a few seconds. So on top of keeping paper out of reach, it’s worthy training your dog the leave-it and drop-it cue just in case you ever happen to accidentally drop something he shouldn’t have. Teaching your dog to trade the paper in exchange for a tasty treat can also come handy when he gets a hold of other things.

Last but not least, for those die-hard paper shredding dogs, it’s worth mentioning the behavior to the vet. In some cases, medical problems or nutritional deficiencies may cause a dog ingest non-food items.

“Tiny chunks of paper are not likely to do harm. But, if a whole piece of paper was eaten it definitely could act as a foreign object and cause an intestinal obstruction.”~Dr. Marie

What’s the Difference Between Dog Howling and Baying?

Dog Howling

While dogs can’t talk, we must admit that Mother Nature has blessed them with the capacity to produce a variety of sounds and at one point or another one may wonder what’s the difference between dog howling and baying.

Most of us are familiar with the sound of dogs howling, dogs are often heard howling at sirens or when the owners leave the house. Baying is typical of certain dog breeds and it may be confused sometimes for howling, but the noise produced is a tad bit different and the purpose may be a bit different as well.

A Word About Howling

Howling is the sound often associated with canines in the wild and is characterized by a prolonged, loud, wailing sound. The howling sound is used by wolves for aggregation purposes, a way to reunite other wolves to gather for the hunt.

It may happen that the wolves are scattered about with some sleeping and others wandering, and being that wolves take a cooperative approach to hunting, it’s necessary for them to unite. Howling in this case therefore elicits social contact.

Howling in wolves has also a social function, when wolves are howling in unison, it creates a sense of belonging, a sense of group cohesion.

As we have seen in a previous article, dogs are different from wolves in many ways, and domestication has brought some changes in the ways dogs communicate vocally. For instance, since dogs no longer hunt for their meals and are fed kibble from a bag, howling to gather a group for a hunt has lost its original function and therefore dogs howl less. Dogs however, bark more considering that barking was selectively bred by humans so dogs could alert them of the presence of other animals or strangers.

Although dogs tend to howl less than wild canines, the howling behavior is often evoked by sounds like sirens, musical instruments such as flutes or harmonicas, other dogs howling or the owner mimicking a howling sound. Howling can also take place in dogs when they are separated from their owners and feel lonely. In this case the mournful howl may denote a dog’s desire to re-unite with his family.

Did you know? When wolves howl together, they harmonize rather than emitting the same notes so that they give the illusion of there being more wolves than what they really are. Recordings of wolves have shown that no wolf wants to end up howling using the same note as another.

A Word About Baying

Over hundreds of years, hunters found the “howling” sounds produced by dogs productive because it carried a long way and was helpful when working with dogs following trails over certain distances. Hunters could loose sight of their dogs because of distance or thick vegetation and their vocalizations could keep them aware about their whereabouts.

Certain dogs were therefore selectively bred over hundreds of years for their ability to “bay,” or “give tongue,” a distinct vocalization that has a tendency to become more intense and enthusiastic the closer the dog gets to the animals that are hunted.

This increase in intensity draws the attention of other dogs and hunters to gather at the trail area or where the animal is cornered.

Did you know? In hunting terms a hound who happens to vocalize when there is really nothing significant going on is called a “babbler.”

“As the scent becomes stronger, suggesting that the pack is now very close to its prey, the baying becomes a bit less melodious, as the individual sound phrases become shorter in duration but more frequent, and the massage now shifts to mean “Let’s get him!” or “Altogether now!”~ Stanley Coren

Howling Versus Baying

Howling is the noise produced by wild canines and in certain circumstances by the domesticated dog; whereas, baying is the sound exclusively emitted by hounds. You’ll therefore have beagles baying when they catch the scent of quarry and coonhounds baying when game has been “treed.”

If the two vocalizations were compared, howling would entail a single note, whereas baying would comprise more variations within the tone and short bursts, explains Stanley Coren, the book “Do Dogs Dream?: Nearly Everything Your Dog Wants You to Know.”

One may also assume that baying is much more enthusiastic than a mournful howl and even though it has an element of “come join me” it’s more geared towards gathering the hunter and other dogs to the area where something exciting was found.

However, as much as baying may seem the result of years of selective breeding, it’s still likely reminiscent of a dog’s ancestors after all, considering that wolves too emit vocalizations upon detecting prey. According to Seton, author of  “Life-histories of northern animals : an account of the mammals of Manitoba page 770, ” a “muster” or a “rallying cry” may be emitted by a wolf upon finding game that is too big for him to confront alone, while a higher pitched howl vibrating on two notes known as the “hunting song, corresponds exactly with the full cry of a pack of hounds on the hot scent!”

Did you know? There are chances that the word beagle derives from the old French word “becguele” meaning “noisy person,” or more literally “bayer” meaning “open throat” due to this dog’s loud baying.

A Guide to Choosing the Right Toys for Your Dog

Choosing a toy for your dog

Choosing the right toys for your dog may seem like an easy task, but have you ever asked yourself if you are really choosing those toys for your dog or for yourself? It’s easy to fall into the trap of choosing what appeals to us, after all, we are the buyers with money in hand and toy manufacturers know that.

Even manufacturers of dog treats manipulate our choices, making dog treats with shapes and colors that are appealing to buyers, but that dogs could care less about. Let’s face it, if your dog was doing the shopping, he would ignore aesthetics and would head for the smelliest, albeit ugliest, dog treats on the market. Choosing the right toys for your dog entails putting yourself in your dog’s shoes and being aware of  marketing ploys that often trick our minds, often at an unconscious level.

Choose the Right Toy Colors…

Color is often not kept in consideration when choosing the right toy for dogs, but it should as it plays an important role in how your dog interacts with the toy. Dogs do not see colors in the same way we do. If we want to put ourselves in our dog’s shoes, we can say that our dog’s color vision is roughly similar to that of a person who is red-green color blind, the technical term would be a deuteranope.  

If dogs were shown a green and red apple, they would have a hard time to discriminate between these two colors. You can see how a dog sees apples or a rainbow in a previous article, how do dogs see colors?

Dogs may therefore not be able to tell well the difference between red and green, but they have a better time detecting blue and yellow.

So what does this mean for dog owners? Based on these findings, it means that we should choose toys that are easier to notice such as blue or yellow (not coincidentally the colors often seen on dog agility obstacles), which is not  that easy considering that many popular dog toys are orange or bright red. Colors that may be appealing to us, but not to our dogs!

So yes, whether you are choosing a Frisbee or a ball to play fetch, your choice of color is important if you want it to stick out, especially for those dogs who love to retrieve toys for you. Choosing a red toy that is hard to distinguish from the green grass of the dog park can make life difficult for Rover.

“Overall, if we want dogs to distinguish between colors, the best colors to use are blue and yellow.” Dr. Sophia Yin, D.V.M, M.S

But Be Ready for Toys Being Torn Apart

When you look at a dog toy, you may see it as something cute or appealing, but again you are likely looking at it from a human perspective. As humans we are stuck into thinking that toys must look appealing and cute perhaps because they remind us of when we cuddled with these toys at night.

Well, this may sound like a a harsh wake-up call, but from your dog’s perspective toys are perceived like prey animals to tear apart. No, dogs don’t play with their Barbie dolls as we do, nor do they cuddle with their toys to feel less scared at night and fall asleep.

Dogs want to chase toys and chew toys with their chompers as if they were prey animals they just caught. They enjoy to the whole evisceration and dissection process. So dog owners should not be upset if Rover manages to behead a teddy bear the first night and “de-guts” it to get all the stuffing out.

This is therefore something to keep into consideration before shelling out a bunch of money on a dog toy. Not surprisingly, sometimes the most fun objects are free, and dogs are often happy to shred boxes and paper just as cats are happy playing with a ball of tin foil.

” I often stop local thrift shops and Salvation Army stores to pick up a few small plush toys which are usually sold for less than a dollar. These are then sacrificed to my dogs who proceed to tear off their heads and limbs and scatter their filling about, much to my wife’s dismay.”~Stanley Coren

Keep Safety Always in Mind…

With a dog’s propensity to tear toys apart in mind, it’s also important to consider safety. Some toys may be OK for small dogs or dogs who aren’t too destructive, but they still require close supervision.

If your dog has a history of ingesting foreign objects skip toys that have pieces that can be torn off and swallowed or toys that can be ripped apart. Also, be aware of the dangers of squeakers.

When working for a vet a few years back, toys with squeakers inside where a big hit, but sadly many dogs managed to get the squeakers out  and ended up ingesting them. This practice often led to blockages requiring expensive surgical intervention. I still remember as of today a dog owner complaining about how a two dollar toy ended up costing her almost a thousand dollars in surgery to get it out.

Sure, not all dogs eat toys when they break them apart, but for those who do, it can be very problematic. So if your dog has a Hoover reputation, look for toys crafted with sturdiness and safety in mind. They might not be as fun, but hey, safety is always paramount. Some toy companies are so confident their toys are sturdy, they have even started to offer money back guarantees if your dog manages to break them apart.

“Because we think that dogs perceive toys in the same way that wolves perceive prey, they prefer toys that either taste like food or can be torn apart, however the latter can cause health problems if the dog accidentally swallows some of the pieces.” ~ John Bradshaw

And Consider Joining In the Fun.

According to a study published in the journal Animal Cognition, 16 Labrador retrievers between the ages of one and eight were provided with different types of toys of  different colors, and with different smells. The toys were given to each dog one at a time until the dogs stopped interacting with them and then were swapped with a different toy.

All dogs in the studies showed interest in the toys, but the interest was rather short-lived. The results suggest that dogs are prone to exploring new objects in their environments, but they quickly get accustomed to their sight, smell and feel, which leads to boredom and little further interest.

What do the results of these studies mean for dog owners? They suggest that dog toys need to have some elements to keep that interest alive. One of the best ways to bring a toy “alive” is by using it to play fetch or perhaps attaching it to a flirt pole.  Balls that bounce around attract because of their unpredictability, Frisbee and tug toys encourage dog and human interaction. Dogs love interaction with their humans and becoming part of the game allows owners to spend quality time with their dogs which also helps with bonding.

““For an animal as social as a dog, toys only become really excited when they are part of a game with a person. Few toys will sustain a dog’s interest for long if the owner is not around to offer encouragement.” ~Bradshaw

And Don’t Forget: Variety is the Spice of Life!

Being too stingy in the toy department may translate into dogs who grow easily bored of their toys. If your dog’s toys are getting dusty, chances are there is not much variety going on.

Choose dog toys of different textures, producing different sounds and with different shapes and sizes, while keeping safety in mind. Then rotate these toys randomly so that they preserve an element of novelty.

This means you might want to keep them out of sight for some time and then bring them back out so that your dog gets to enjoy them again and again. Another idea is to get creative and change a bit how your every-day dog toys look or smell.

You can try to stick some toys in your dog’s bag of kibble for a few hours so they get impregnated with its taste and smell, or if feasible, you can try sticking a toy inside another one and letting your dog work on dislodging them. You can also hide your dog’s favorite toy under a blanket or bench and let him find it, or turn it airborne by hanging it to a rope by a tree. Just think outside of the box and get creative!

“Instead of leaving toys out all the time so that they lose their appeal, toys can be put out of sight. Old toys can be rotated back into sight as somewhat ‘new’. Like old Seinfeld re-runs.”~Julie Hecht

Did you know? According to 2015-2016 APPA National Pet Owners Survey, dog owners spend an average of $47 annually for dog toys.

What’s Up With Dogs Chewing Through Drywall?

Guilty dog face

Dogs may chew and eat the oddest things, and the behavior of dogs chewing through drywall can certainly be classified as one of dog’s most peculiar behaviors. Why would a dog chew through drywall? It might not make sense to us, but when we see things from a dog’s perspective, chewing and even eating the drywall, may start to make sense.. Well, perhaps we should say, it becomes a tad bit more understandable. If your dog is chewing through drywall, you may be wondering why he does that, and how to fix it. So what’s up with dogs eating through drywall, and dogs chewing up the baseboards or pulling off wallpaper? And most of all, what can be done to stop your dog from remodeling the whole house?

Busting the Boredom

Let’s face it: dogs have teeth and those chompers just happen to be in search of something to chew on. In the great outdoors, dogs often find handy things to chew on, perhaps a branch, a little twig or some bone some other animal left behind, but in a domesticated setting, dogs often don’t have much assortment of things to chew on.

This lack of sensory enrichment leaves a vacuum for fulling this natural desire to chew.

Then one day, it could be your dog happens to be sitting next to the drywall, bored and with nothing else to do, and he may happen to casually lick the corner of the wall, and next thing you know, he’s chewing on it.

In this case, chewing on the drywall provides sensory reinforcement, in other words, it just feels good. And when something feels good, dogs will want to experience it over and over, so soon the habit puts roots and next thing you know, you’re walls will start looking like Swiss cheese!

Dealing With Anxiety 

A dog chewing through drywall isn’t always a bored dog, sometimes the behavior may stem from anxiety. If your dog is anxious about noises in general or scary events such as thunderstorms or construction workers drilling holes in an apartment nearby, he may experience intense anxiety and fear.

If your dog is in a small room or if he hides in a closet, his panic may cause him to dig or chew the drywall in a desperate attempt to escape the threatening situation.

Another common anxiety trigger in dogs is being left alone. Dogs who panic when their owners leave a room or the home may scratch at doors, chew windows and drywall in hopes of being reunited with their owners.

“I’ve seen them go right through windows, and chew through doors, drywall, even chain-link fences, breaking off their teeth and nails. They get into such a level of panic that they just aren’t thinking.” ~Stephen Blake, holistic veterinarian

Searching  for Critters 

Is your dog staring intently at walls and sometimes sniffing and whining in the evening? Most likely your dog is not sensing the paranormal and hunting for ghosts, rather, it’s more likely that he’s sensing the presence of some nocturnal critter who is likely living in your house.

What critters may be making themselves at home? It can be mice, snakes, lizards, crickets or even termites. You might not detect them, but your dog with his powerful sniffer and sensitive ears can, and chewing through the drywall may be his attempt to get to them.

Keep in mind that critters may be hiding in your attic, under the deck, in the garage, in a closed closet and inside the walls.

Grabbing Some Attention

Some dogs may resort to chewing things in hopes of getting attention. Dogs who are bored or enjoy social interaction with their owners and feel socially deprived, may resort to all sorts of behaviors in hopes of getting their owners to interact with them. Sometimes, bored or socially deprived dogs will even try things that lead to negative attention such as being scolded or pushed away just for the sake of getting their owner to stop watching television and start interacting with them.

So if chewing through the drywall gets your attention (and it certainly does!), this moment of brief attention, even if of the negative type may reinforce the wall-chewing behavior. And if you fail to provide attention immediately, your dog will likely chew for longer in hopes of eventually getting it (extinction burst). Not always though the attention has to be of the negative type though. If your dog is bored and every time he chews on the drywall, you play with him to distract him or take him on walk, next time, he may chew in hopes of play time or a walk.

Dealing with Pica

In some cases, chewing through drywall may be a sign of pica. Pica is a condition where dogs become attracted to eating nonfood items like rocks, wood, drywall, socks, and coins. Basically, affected dogs will eat objects that are not considered part of a normal dog’s diet. It is still not well understood what exactly may trigger pica. Is it boredom? A health problem? A behavioral one?

Some theorize that it may stem from nutritional deficiencies; however, no nutritional studies have ever backed up this theory. Also, with most of today’s current commercial dog foods being balanced and complete, it’s  unlikely for dogs to have nutritional deficiencies, explains veterinarian Dr. Heindel. 

It could happen though that dogs remain stuck in an “oral phase“from when they were puppies, she adds. Other possible causes are underlying digestive disorders or  metabolic disorders, which explains why it’s a good idea for owners of dogs fixated with eating nonfood items to start with a vet visit to rule medical conditions out.

“Dry wall contains gypsum which is a mineral congomleration which includes a large amount of calcium sulfate. Very similar to bone! So, some dogs will chew dry wall because they discover it is like bone. Have the blood tested. You might find a low calcium level.” ~Dr. Ralston

Tips to Stop Chewing Through Drywall

As with many other dog behaviors, it’s important to go to the root of the problem and tackle the underlying cause. A vet visit may be a good place to start just to ensure there’s nothing going on in the health department.

With health issues ruled out, then it’s time to roll up sleeves and put on an investigative hat to pinpoint the problem. This is best done with the help of a professional, even because certain underlying causes of chewing the wall may require professional intervention as tackling these issues may not be easy.

For instance, if your dog chews through drywall because he is anxious, you will likely need to get help from a professional to implement a systematic desensitization program. Whereas, if there are critters in the wall, you will need to enlist the help of a local exterminator.

Bored dogs, or dogs in need for attention, benefit from being provided with more exercise and mental enrichment. Provide several safe chew toys of different textures for sensory enrichment and don’t forget to rotate them to keep a sense of novelty. Chewing dogs should be blocked from gaining access to the drywall area while the dog is trained to learn that other behaviors garner attention such as calmer, more desirable behaviors garner attention. With energy drained, the introduction of interactive toys and attention provided only when desirable behaviors take place, the drywall will become less and less attractive over time.

Dog Word of the Day: Spaniel Dog

Spaniel dog running

The world of dogs breeds is quite vast and in order to keep some sort of order, dog breeds are often divided into several categories often based on the type of work they were bred for and the spaniel dog sub-group is one of them.

What is a spaniel dog? Spaniel dogs were hunting companions who were selectively bred to accomplish precise tasks to help out hunters in areas of dense bush.

Today, there are several dog breeds listed under the spaniel dog category. On top of being used as hunting companions, spaniels dogs share some general distinctive physical traits which makes them quite easy to identify when compared to other types of dogs.

What Were Spaniels Bred For?

As mentioned, spaniels dogs were bred for helping hunters. What did they do though exactly? Spaniel dogs are a type of gun dog, meaning that they assisted hunters using shotguns. In particular, spaniels were employed to flush out birds from dense bush.

Basically, spaniels would be quartering in close proximity to the hunter, sniffing around with their powerful noses in search of quarry in a zig-zag fashion. If the spaniel did find the birds, he would then drive them out of their hiding spots in dense bushes so that the hunter could aim and shoot.

The term used for depicting the action of driving the birds out of their hiding spots is “flushing” but the term “springing” can also be used. A spaniels’ flushing is therefore quite a different task and much more dynamic compared to the motionless pointing typical of pointers and the setting typical of setters.

Some spaniels were mainly used on land, while the larger specimens were also trained to retrieve downed birds from lakes and streams. Several of these spaniels had curly, water-repellent coats.

Spaniel Dog Traits

On top of being bred to flush birds out of bushes, spaniels share some physical traits that make them distinguishable from other dogs. Spaniel dogs typically have long, drooping ears and a long silky coat. The coat is wavy, particularly on the ears, chest, abdomen and legs.

Spaniels are known for having a a gentle expression courtesy of their soulful eyes and their stubby or long tails are often wagging quickly.

When it comes to personality traits, spaniels are known for being highly intelligent and affectionate. Of course, these are general traits considering that it is difficult to narrow down specific traits when every spaniel is blessed with its own unique personality. Even within a litter of spaniels the differences between one pup and another despite being of the same breed can be quite broad.

Spaniel Dog Breed List

What dog breeds are categorized as spaniels? The American Kennel Club lists most spaniel dog breeds under the sporting group which encompasses pointers, retrievers, setters and spaniels. The spaniels found in the American Kennel Club sporting group therefore consist of the following:

The American Water Spaniel

The Clumber Spaniel

The Cocker Spaniel

The English Cocker Spaniel

The English Springer Spaniel

The Welsh Springer Spaniel

The Field Spaniel

The Irish Water Spaniel

The Sussex Spaniel

The Boykin Spaniel

Other spaniels include the Cavalier King Charles Spaniel, Blue Picardy Spaniel, German spaniel, Russian spaniel, and there are several more.

Did you know? The Brittany was once known as the Brittany spaniel but the word spaniel was then dropped because it turned out this dog was more of a pointer than a flusher. Since the 1980s the Brittany is therefore considered a pointer and the word spaniel is no longer used.

What Dog Breed is Nicknamed the Jumping Up and Down Dog?

The basenji dog breed

Among the world of dogs, there are a variety of colorful terms used and some dog breeds are known by their nicknames. Have you ever heard about a dog breed nicknamed the “Jumping Up and Down Dog?”

This nickname is quite curious and it may bring mental images of dogs jumping up and down like kangaroos or some dog on a pogo stick. Here’s a little hint: as one may assume, it would take quite an agile type of body for a dog to jump up and down. So today’s dog trivia question is

What dog breed is nicknamed the “Jumping Up and Down Dog?

A – Whippet

B – Italian greyhound

C – Australian Kelpie

D – Basenji

The correct answer is: drum roll please…

The correct answer is D, the dog breed nicknamed the jumping up and down dog is the basenji.

Origin of Name 

Perhaps most people know the basenji by his other more popular nicknames “the barkless dog” or “the soundless dog” which obviously refer to this breed’s tendency to yodel rather than bark, but the jumping up and down dog nickname merits some attention too.

Curiously, this nickname derives from this breed’s African name “m’bwa m’kube m’bwa wamwitu” (now try to pronounce that!which translates to the “jumping up and down dog.”

Of course, the next question is “why are basenji known as the “jumping up and down dog” in the first place?”

Basenji Hunting Style 

The basenji dog breed is quite an ancient breed originating from the Democratic Republic of the Congo in Africa. Basenjis have a history of being used as hunting dogs, chasing animals and flushing them into nets for their hunters. Basenji were also used to keep the rodent population under control.

Their nickname “the jumping up and down dog” derives from this dog breed’s tendency to leap high over the tall grasses of his native land  so to take a quick peek around, checking for prey while airborne. Many basenji owners also report seeing their dogs stand on their rear legs,in a meerkat-like manner when their dogs are curious about something.

” It is marvelous to see one jump up and down in five feet high elephant grass, he almost seems to hover in the air at the top of his jump whilst he has a quick look around and scents the air. Hence, one of the African names M’bwa M’kube M’bwawamwitu, the jumping up and down dog.” ~Basenji Club of Great Britain

A Body Built for Hunting

If we looks closely at the basenji, we will see a dog breed that was purposely designed for hunting. Curiously, the American Kennel Club bred standard informs us that this breed hunts both through sight and scent.

The whole facial features of the basenji denote alertness. The basenji’s ears are erect, ready to capture the faintest sounds. Courtesy of this breed’s smooth musculature, basenji move in an effortless gait that is depicted as resembling a racehorse trotting.

Interestingly, basenji are known for lacking the typical doggy odor of many dogs, a trait that may have helped them go undetected by other animals when hunting. The fact that basenji are bark-less may stem from their primitive heritage as silent hunters. Barking was a trait that was selectively bred by humans so dogs could alert them about the presence of animals or intruders. A dog’s ancestors were quiet hunters.

Did you know? Because basenji are silent on the trail, Congolese natives have them wear a bell made of wood, or iron, or the shell of a Borassus nut so they are aware of their whereabouts.

Not Everyone’s Cup of Tea

A dog that doesn’t bark but yodels, that’s virtually odor-less and that’s blessed with exotic looks, is sure to draw attention and many people may feel tempted to open their hearts and homes to a basenji, but they’re not everyone’s idea of the ideal dog.

Basenjis do cherish time with their families, but as a primitive breed with a history for hunting, they have characteristics that can make them not everyone’s cup of tea.

Basenji are very inquisitive, energetic, highly intelligent, independent and have a strong prey drive. They are escape artists who will do what it takes to get to the sight or scent of something that attracts them regardless if it means jumping over, crawling under or digging his way out. And when it comes to training, you really have to work on making it fun and worthy of his attention. Fail to do that and your basenji will walk away and look for something better to do.

Did you know? The Basenji Club of America offers a Basenji University guide for owners. The guide has interactive tests to help learn the basics about this breed.

I am Your Dog’s Gums

Happy dog

Unless your dog is yawning, you dog’s gums are for the most part hidden from plain view, but just because you don’t see them doesn’t mean they are a part of your dog’s body that you should neglect! “Out of sight, out of mind” is a saying that shouldn’t apply to your dog’s gums. Forget about this important body part, and the impact can have a negative effect on your dog’s overall health, sometimes even causing debilitating conditions.

Your dog’s gum are an important piece of dog anatomy and can provide quite some relevant information about your dog’s  overall state of health. So, don’t forget about your dog’s gums and make it a habit of paying  attention to how your dog’s gums look and feel when he’s healthy so that you have a baseline to refer to as needed.

Introducing Your Dog’s Gums

Hello, it’s your dog’s gums talking! Feel free to just call us gums, but if you want to be more technical you can also call us “gingivae.” Who are we? We are simply that lining of tissue that surrounds your dog’s teeth forming a tight seal around them.

Just like in humans, we are normally a healthy pink color, but unlike most humans, it’s not abnormal if you happen to notice some pigmented spots on us.

Some dog breeds and dog mixes have black in their mouths either on our surface, roof of the mouth or tongues or generally all around the dog’s mouth. Of course though, if your dog has developed a totally new spot you have never seen before, best to have it checked out by a vet just to play it safe!

We Play a Protective Role

When we are nice and healthy, we form a tight, firm seal around your dog’s teeth. As you already know, your dog’s mouth is used to chew and ingest food and our job is to prevent food particles and bacteria from invading vulnerable underlying tissues along with the roots of your dog’s teeth.

We Provide Hints on Health

Dog gums

Because we are normally slimy and vascular in nature (we’re closely related to your dog’s circulatory system), we can give you some insights into your dog’s overall health. Dogs don’t get pale skin on their faces as humans do when they are sick, but take a peek at us and we can provide several hints as to how your dog is doing. Now, this explains why your vet skips feeling your dogs’ nose when your dog’s feeling under the weather and instead goes straight to taking a peek at your dog’s mouth instead.

Normally, when dogs are healthy, we are of a nice bubble gum pink color. This pink color is great news as it means your dog is getting enough oxygen circulating in his bloodstream. Any other gum color in dogs may be a sign of trouble and in some cases even an indication that the dog needs immediate care.

Knowing your dog’s normal gum color and how to check your dog’s gum can turn helpful should you  find yourself one day calling the emergency vet wondering if you need to take your dog in and they ask you to check the color of your dog’s gums.

Training your dog from an early age to have his mouth checked with praise and treats is extra helpful. Also because you may want to also learn how we feel. We are normally wet, slippery and slimy in healthy, well hydrated dogs. If we feel dry and sticky this can a sign of dehydration which can be seen when dogs are vomiting a whole lot or sick and in need of prompt veterinary treatment. Last but not least, don’t forget to learn how to check your dog’s capillary refill time.

When Things Go Wrong

Remember how we said that when we’re healthy we form a seal around your dog’s teeth to protect them? Well, problems start when we loosen up and that tight seal is lost. Why do we loosen up? It all starts with the presence of a sticky, bacterial bio-film.

After your dog eats, a sticky film made of a combination of bacteria, carbohydrates, food particles, and saliva forms and sticks to your dog’s teeth.

This sticky bio-film is commonly known as plaque. You can detect plaque forming on your teeth when you fail to brush your teeth on time, the same happens in dogs.

Inflammation of Dog Gums

Unless your dog’s teeth are brushed on a routine basis, this plaque will keep accumulating and will stick around your dog’s teeth, the gingival grooves and under the gum line. When we detect this plaque getting in our way, our first reaction is to become inflamed. We will therefore become angry and red, swollen and we may even bleed, all symptoms of condition known as “gingivitis.” If the plaque is not removed in a timely manner by brushing, courtesy of minerals in a dog’s saliva, this plaque will start to harden, and in a few days, it will calcify turning into what’s known as tartar or calculus, an unsightly yellow/brown coating that is difficult to remove. The good news is that gingivitis is reversible with thorough teeth cleaning and polishing along with the owner’s daily care, as no bone loss has occurred at this stage, explains veterinary dentist Dr. Jean Hawkins.

Receding Dog Gums

Dog with red gums and tartar

Left untreated, gingivitis worsens and will develop into periodontitis, a condition that affects anything surrounding a dog’s teeth including all the structures that hold the teeth in place. So when us gums are affected, we will no longer adhere to your dog’s teeth like a cuff. Instead, we will start pulling away from your dog’s teeth (gingival recession) up to to point of exposing the roots which are normally covered by us.

Soon, since we are no longer holding on tightly to provide our protective role, bacteria will start reaching the roots of the dog’s teeth and the jawbone, releasing toxins that eat away bone tissue.

Bone loss will weaken all the dental structures that keep a dog’s teeth anchored in place such as connective tissue fibers and ligaments, providing less and less support. Next, the bone around the tooth is destroyed leading to loose, painful teeth which can affect the dog’s ability to eat properly and even digest.

“It’s not unusual for middle aged dogs to lose teeth. In most cases this occurs when there is gum disease (gingivitis) which can then spread to the tissue that holds the tooth in (periodontitis).” Dr. Pete

Did you know?  According to the American Veterinary Dental College, by three years of age, most dogs have signs of periodontal disease

Systemic Disease

Remember how we talked about our importance in a dog’s health and how neglecting us can lead to serious disease? Well, here are the hard to swallow facts. Because we are very vascular, bacteria can easily gain access though us to a dog’s bloodstream and circulate throughout his body. While these bacteria may be filtered out by the dog’s liver and kidneys, tiny abscesses may develop on these organs which disrupts their normal functioning leading to liver or kidney disease. And should these bacteria happen to attach to the dog’s heart valves instead, they can cause endocarditis, a serious  inflammation of the inner layer of the heart. Definitely, something to be aware of!

“As the animal chews its food, the infected and inflamed gums bleed, and a shower of very aggressive bacteria enters the blood stream. These germs are carried throughout the body and can cause infection in many areas.”~ Dr. Fraser Hale, veterinary dentist.

Lumps, Bumps and Growths

As with other parts of your dog’s body, we may sometimes have odd lumps, bumps and growths growing on us.

Sometimes we may enlarge causing  a condition known as gingival hyperplasia. Epulis, also known as gum boils and viral papillomas also known as oral warts, are examples of some benign growths that may grow on us in a dog’s mouth, but unfortunately, sometimes cancerous growths may grow on us as well.

Malignant melanomas, squamous cell carcinomas and fibrosarcomas are cancerous growths that may grow on us. If your dog has a suspicious lump, bump or growth on his mouth, please have him checked out promptly.

 As seen, we are important structures, meant to keep your dog’s mouth and body in good health! Keep us in good shape by protecting us from the accumulation of plaque, and while you are it, remember to take a good peek at us so to get to know our normal color so, if need be, you can readily recognize early signs of trouble. I hoped this has helped you understand us!

Discovering Dog Breeds With Wrinkles

Dog playing ball

When you think about dog breeds with wrinkles, perhaps thoughts of adorable rumpled little puppies come to mind. If you find dogs coming in a wrinkly-skinned package irresistible, rest assure you are not alone. Countless dogs lovers are drawn to those corrugated pumpkin faces; however, it’s important to recognize that all those wrinkles may need some TLC.

Also, when considering opening your heart and home to a new dog, it’s important to look beyond appearance and consider whether your lifestyle is a good match for those dog breeds with wrinkles. Following are  dog breeds covered with wrinkles along with some interesting discoveries about the purpose of those wrinkles.

1) The Wrinkly Shar-Pei

Say the word wrinkles and images of Chinese shar-pei come often to mind. Some people nickname these dogs “little hippos” or “the dog in need of ironing” because of these dogs’ wrinkly appearances.

When shar-pei are puppies they are adorable piles of wrinkles. As they develop though, they tend to “grow into” their loose skin, and it’s time to say bye-bye to the skin folds on their legs flanks, and bellies. However, the profuse wrinkles on the head, neck and withers are there to stay–and for good.

Shar-pei are quite ancient dogs originating from the south of China and dating back more than two thousand years. What’s the purpose of shar-pei wrinkles? It appears that the shar-pei’s loose skin and prickly coat was developed to help them fend off wild boar. Later on, when shar pei were employed for dog fighting, their loose skin once again came handy, making them capable of turning and biting back the opponent.

Did you know?According to research by the Universitat Autònoma de Barcelona the recent increase in thickness and wrinkles in the shar-pei dog breed is the result of an inherited skin disorder known as cutaneous mucinosis which causes a build-up of mucin in the layers of the skin.

“The loose skin and wrinkles covering the head, neck and body are superabundant in puppies but these features may be limited to the head, neck and withers in the adult.” American Kennel Club

2) The Wrinkly Pug

These small dogs are blessed with wrinkles and a clown-like personality that is likely to brighten most people’s days. And this is not surprising if we look back at the pug breed’s history.

The Pug originated from China and is quite an ancient breed that has been known since before 400 BC. Pugs were selectively bred to provide companionship to Chinese emperors, making them much cherished and pampered lap dogs. These fortunate pooches were highly valued and there’s belief that they were even guarded by soldiers.

Later on, pugs were spread to other areas of Asia and in Tibet, where they provided companionship to Buddhist monks who kept them as pets in their monasteries.

Why do pugs have wrinkles? The features of pugs along with their wrinkly faces have been selectively bred by Chinese breeders because they were appealing, or better adorable to say the least.

Did you know? According to Animal Planet, Chinese breeders were hoping to create a wrinkle pattern on the pug’s foreheads that reminded them of the Chinese character for “prince.”

“The head is large, massive, round – not apple-headed, with no indentation of the skull.The wrinkles are large and deep.” ~American Kennel Club

3) The Wrinkly Neapolitan Mastiff

You won’t likely see these dogs much around as they’re not too popular abroad, but they are sure to leave an impression on those who see these wrinkled fellows for the first time.

First off, these dogs of Italian descent are massive, often weighing over 150 pounds.

Secondly, those wrinkles are quite impressive! The wrinkles are every where so much so you’ll  literally see them rolling as the mastiff dog moves about, but they are especially noticeable on the head and dewlap.

The presence of wrinkles and skin folds in some parts of the face are so typical of the breed that their absence is considered means for disqualification in the show ring.

Neapolitan mastiffs derive from ancient molosser bloodlines that descended from Roman war dogs. They were then employed as loyal estate and farm guardians.

Why do Neapolitan mastiffs have wrinkles? The wrinkles along with this breed’s other unique features are the result of years of selective breeding. With a history of war dogs and then estate and farm guardians, most likely the mastiff’s wrinkles were appreciated because they gave these dogs an imposing look. According to the book  The Complete Dog Bookby the American Kennel Club, there are chances that farmers of the Neapolitan area of southern Italy purposely bred an “alarmingly ugly dog” with looks that would have repulsed any invaders. But they’re far from being ugly, aren’t they?

The face is made up of heavy wrinkles and folds. Required folds are those extending from the outside margin of the eyelids to the dewlap, and from under the lower lids to the outer edges of the lips.” American Kennel Club

4) The Wrinkly Dogue De Bordeaux

Does the movie Turner and Hooch bring any memories? Hooch was a Dogue de Bordeaux (French mastiff) and he played the role of a troublesome pooch who managed to tear police investigator Scott Turner’s house apart and chew on his car. Also known as French mastiff, just like the Neapolitan mastiff, the Dogue de Bordeaux descends as well from the ancient molossers and inherits their massive body and large head.

Dogue de Bordeaux are one of the most ancient French breeds but their origins are a bit shrouded in mystery. Some believe they derive from  bullmastiff and the bulldog, others believe they derive from the Tibetan Mastiff or the Dogues de Bordeaux of Aquitaine. Regardless, they have quite a colorful history being used for guarding flocks, hunting bears and foxes, bull-baiting and even as war dogs.

“The head is furrowed with symmetrical wrinkles on each side of the median groove. These deep ropes of wrinkle are mobile depending on whether the dog is attentive or not.” ~American Kennel Club

5) The Wrinkly Bulldog

Another dog breed known for its wrinkles is the bulldog, a dog breed originating from the British Isles. Originally bred as a butcher’s dog for the purpose of subduing animals for slaughter, the bulldog was then employed in the bloody sport of bull baiting, a cruel practice that was fortunately outlawed in England in 1835.

The bulldog today has changed a lot in both looks and temperament and has now becomes a beloved companion.

The American Kennel Club breed standard depicts the bulldog has having the head and face covered with heavy wrinkles and two loose pendulous folds of skin forming the dewlap.

Why do bulldogs have wrinkled skin? There are many theories, a common one is that in the old days of baiting, those wrinkles helped channel blood away from these dog’s eyes, but there are other explanations out there. According to Animal Planet their wrinkles may have helped them better fight against their opponents. As with the shar-pei, even if they happened to be gripped by an opponent, their loose, wrinkly skin allowed maneuverability, so that they could defend themselves and fight back. The Bull Dog Club of America also mentions that the loose skin came handy when bull baiting preventing penetration of the bull’s horns.

Did you know? The big skin fold often found between the bulldog’s nose and eyes is known as the “nose rope.”

“Every point of conformation was selectively bred into the Bulldog to prevent it from injury as it went about the business of overcoming a bull…Forehead and face wrinkles directed the bull’s blood away from the dog’s nose and eyes…The looseness of the skin of the Bulldog’s body often served as a deterrent to penetration of the bull’s horns. “~Bull Dog Club of America

6) The Wrinkly Bloodhound

The blood hound was selectively bred for its wrinkles and for a very good reason: those wrinkles helped these fellows out in their jobs!

No, contrary to what the name may suggest bloodhounds weren’t used for the bloody sports as several of the other wrinkly fellows we have seen. Instead, there’s belief that bloodhounds were bred by monks of the Abbey of Saint Hubert for the purposes of tracking deer and boar.

Specimens of these hounds were often given as a gift to the King of France. Their name derived from the fact that they were were full “blooded” hounds and prized gifts among kings and nobles.

Why do bloodhounds have so many skin folds? It’s likely that, along with their pendulous ears, droopy jowls, saggy skin folds, the wrinkles help these dogs track scent. Basically, the long ears act as “brooms” sweeping up scent particles upward to reach these dog’s potent noses, while according to PBS Nature, that loose skin and wrinkles on the bloodhound’s face and neck help trap some of those scents.

Did you know? The brow wrinkles in the bloodhound may have a protective function. Since these dogs are perpetually tracking with their heads low to the ground,  those wrinkles may help protect their eyes from the dangers of sharp vegetation.

“The head is furnished with an amount of loose skin, which in nearly every position appears superabundant, but more particularly so when the head is carried low; the skin then falls into loose, pendulous ridges and folds, especially over the forehead and sides of the face” ~American Kennel Club

Basic Dog Wrinkle Care

While all those wrinkles may look appealing, as mentioned, wrinkles in dogs may need some care. Dogs with deep wrinkles and skin folds are prone to getting food, dirt and moisture trapped within all those nooks and crannies. On top of trapping dirt and debris, wrinkles are also prone to constant friction.

Wiping the wrinkles with hypoallergenic baby wipes or wipes especially designed for wrinkly dogs can help keep the wrinkly coat clean and prevent annoying skin infections. Areas that are particularly prone to annoying irritations and infections and that require more care include the lip folds, facial folds, arm pit areas and the base of the tails.

Impact of Exercise on Puppy Growth Plates

Dog jump

When it comes to puppies, it may be tempting to exercise them so to drain that boundless puppy energy, but it’s important to consider the impact exercise may have on puppy growth plates. When can I take my puppy jogging with me? When can my puppy start competing in agility classes? When can my puppy follow me on a bike? These are all important questions that puppy owners often ask. While there’s no question about the fact that puppies love romping and moving about, even up to the point of exhaustion, as with most things in life, too much of a good thing can have an impact, and in this case, the impact can have deleterious effects to the the pup’s developing skeletal system.

What are Puppy Growth Plates?

Puppy bones are surrounded by layers of soft developing cartilage tissue that are found towards the end of most long bones. These areas of soft cartilage are known as growth plates or more technically, epiphyseal plates.

Scottish surgeon John Hunter studied growth plates in great detail in the late 1700s. His studies on growing chicken revealed that bones do not develop from the center outwards, but rather bones grows lengthwise as new bone is generated at the end of long bones, right where the growth plates are located.

John Hunter’s studies granted him the nickname of “father of the growth plate” and his contributions have surely helped both humans and animals.As one may imagine, since growth plates are made of soft, developing cartilage, they are vulnerable and can be quite prone to injury.

Puppy Growth Plate Damage

When it comes to the skeletal development of puppies, it’s important that the puppies’ bones go through even growth, basically, synchronized growth that occurs evenly and as close to the same rate as possible.

If an injury to a growth plate occurs, the growth of damaged cells may slow down and come to a halt meaning that there may no longer be growth on one side. When the growing of the affected side is delayed and stopped, the unaffected, healthy side may continue to grow and this unevenness may lead to potential deformity.

Most commonly, the forearm area is the affected. When the injured growth plate of the ulna stops growing, the radius bone will keep growing potentially leading to one bone that is slightly longer than the other and causing bowed legs, explains veterinarian Dr. Gary.

Puppies are particularly prone to injury during strenuous exercise because they lack coordination and don’t have a lot of muscle strength. On top of from excessive strenuous exercise, injury to a puppy’s growth plates may occur from a fracture as can happen from a fall or being hit by car. While these fractures may heal, the bone may grow unevenly which, as we have seen, can lead to a deformity of the bone. If you therefore suspect injury to your pup’s growth plates or witness any abnormalities, see your vet at once.

Did you know? Some dog breeds have a mutation in their genes responsible for transforming cartilage to bone. This causes shortened legs, a condition known as achondroplasia as seen in basset hounds, dachshunds and corgis.

Preventing Puppy Growth Plate Injuries

Puppies need proper exercise as they grow and develop, but moderation is key. It’s therefore important to be careful especially with high impact activities such as repeated jumping as to catch a Frisbee, hurdling through obstacles or jogging, especially over hard surfaces such as asphalt or concrete. Turf offers a more forgiving surface and better traction compared to hard cement or asphalt. Sustained vigorous exercise, leg-twisting activities or very rough play should be avoided.

When can my puppy start competing in agility? Many puppy owners may find it surprising when trainers tell them that their puppies are too young to start competing in agility. However, puppy owners may start their puppies on some pre-agility basics such as getting familiar with agility obstacles and other skills/ foundation exercises that aren’t high impact and therefore won’t put strain on those delicate growth plates. Consult with your vet and agility trainer for when you can get started.

Did you know? In a study involving 203 agility dogs, it was found that the tibia, radius and ulna were significantly longer than the femur and humerus, respectively, in dogs that were spayed or neutered at or prior to 8 months of age as compared to intact dogs.( Source: M.C. Zink)

When Do Puppy Growth Plates Close?

As puppies develop, their growth plates close as calcium and minerals harden the soft areas but exactly when do these puppy growth plates close? Since dogs develop at different rates based on size and breed, there is no one rule that fits all.

For example, growths plates in a Chihuahua will close much sooner than a larger breeds such as a great dane. Generally most skeletal growth occurs when puppies are between 3 and 6 months of age. Afterward, longitudinal growth decreases, and by 10-12 months or up to 18 months in the large/giant dog breeds, most growth plates have fused and closed. However, some suggest the process can taken even up to 20 months.

How can a dog owner know for sure whether a dog’s growth plates have closed or not? The best option is to talk to the vet before starting puppies on any rigorous exercise or sport training regimens.

For the best peace of mind, consider than with an x-ray it is possible to see whether the bones have fused or not. On an x-ray the vet will be able to tell whether the growth plate has morphed into a solid, integral part of the bone leaving its only trace of existence under the form of an epiphyseal line, as seen in the picture on the right.

“Most sports medicine veterinarians recommend to not begin training until growth plate closure which depends on the size of the breed and can be anywhere from 10 months to 18 months of age.”~Dr. Wendy Baltzer

Effects of Hormones 

Hormones are known for playing a role in a puppy’s growth plates and skeletal development. As we have seen, growth plates tend to generally close when a dog is 12 to 20 months old depending on breed and size. This coincides with the end of puberty, therefore in intact dogs growth plates close after exposure to hormones.

Male and female sex hormones are known to play key roles in closure of bone growth plates. Therefore, if a dog is altered (spayed or neutered) prior to puberty, there is a delay in the closing process, which causes affected dogs to develop a rather leggy appearance which makes them more likely to suffer from orthopedic problems such as hip dysplasia, CCL injury and possibly even bone cancer.

Delaying  neutering in larger dog breeds may help reduce the incidence of these orthopedic conditions.

“The effects of neutering during the first year of a dog’s life, especially in larger breeds, undoubtedly reflects the vulnerability of their joints to the delayed closure of long-bone growth plates, when neutering removes the gonadal, or sex, hormones.” ~Benjamin Hart
Did you know? A Salter-Harris fracture is a fracture involving the growth plates. This classification system categorizes dog growth plate fractures into several types as seen in the chart below.
