If you’ve ever had dogs, then you understand what I am talking about when I refer to teeth chattering. Certain situations in which dogs may click their teeth as if they was cold and make the sound of chattering.

There are a few possible reasons why dogs be able to do this. The majority of the reasons aren’t serious but a few of them may be cause for concern.


Harmless Reasons for Teeth Chattering

Scent Collection

Sometimes dogs talk about its teeth when it’s noticed a place that an animal has peed on or after sniffing the back of another dog’s.

The nose of a dog has what’s known as a vomiting organ that allows dogs to “taste” a scent. The scents dogs emit are used to communicate with other dogs, mostly for reproductive reasons, however they can also be used for other social reasons.

The odors of these odors require a pheromone to get into contact with the organ that produces vomeronasal so that it can discern the messages the scent is sending the dog. The organ’s openings are found inside the mouth of the dog. dogs will talk and utilize its tongue to transfer that scent into the vomiting organ.

The type of chattering that occurs in teeth is more prevalent in male dogs. Some believe it is because females are making use of their urine to signal that they’re pregnant. Male dogs sometimes employ this method of chattering to understand what the woman is saying. The male dog will get direct messages from female’s eye.

Stress and Anxiety

Teeth chattering may be observed when dogs are stressed or anxious. Dogs who show separation anxiety may also display chattering when their stress levels start to increase. Some dogs chatter about their teeth even before owners are allowed to leave the premises.

Stress can manifest in a variety of forms , and teeth chattering could be the direct result. If a dog hasn’t been socialized properly and placed in an unfamiliar or uncomfortable circumstance, it’s normal to feel a little anxiety. If the experience was particularly stressful for the dog, it may keep on chatting following the incident.


Like barking and the body language of dogs, they also use chattering to convey messages. For instance, if another dog comes up to your dog and it starts to chatter about its teeth, it’s likely that it is feeling threatened or simply excited to make the new person. It is important to watch the dog’s body language along with the chattering of teeth to determine the difference between excitement and fear.

The act of chattering by itself is not dangerous but it can provide clues as to what your dog’s likely to do the next time. If it’s chatting in fear of being threatened, it may be necessary to get it from the situation.


If a dog believes that something good is likely to happen, it will exhibit an increased energy level and engage in a chattering.

This is a peculiar behavior that dogs can exhibit when they are extremely enthusiastic and happy about something. If you dog seems predisposed to this, you could be aware of it each when your dog is going for walks, plays with a pet or is about have a meal.



The fact that a dog is covered in fur doesn’t mean they’re immune to cold. Dogs are also susceptible to cold, and are recognized as shivering!

That constant, uncontrollable teeth chattering shiver.

Teeth Chattering when Smelling

It’s an unnatural behavior for us as human beings: teeth chattering while you smell.

Dogs do not just smell through their noses. They also have a second device that assists in the sense of smell The system of the vomeronasal, with the openings being located within the mouth.

It’s true, your pet has a second nostrils inside his mouth.

To make use of these features, one must use his mouth in bizarre ways.

One of these methods is teeth chattering.

Slowly and carefully This behavior can cause scents to be carried into the dog’s mouth. the system of elimination can be able to detect them.

The behavior usually occurs usually after the dog smells, or tastes something that is particularly delicious or unpleasant. A delicious steak cooked in the barbecue or the smell of a skunk may trigger teeth chattering.

Communicative Teeth Chattering in Dogs

Dogs communicate with each other in a variety of unique ways. Chattering with teeth is among the most bizarre, but it’s actually meant to be that way.

It’s known as displacement, and it’s believed to be a defense method used by dogs that fear or are scared.

If your dog comes across an unfamiliar dog that appears to be unfriendly, they may start to chatter with his teeth. This can be a method for the dog to relieve his anxiety which we’ve discussed previously.

It’s also meant to annoy the dog in front of him as well as distract it, pulling focus away from the dog’s chatterer.

I hope that the dog will forget his previous unfriendly behavior and focus on the bizarre click sound.

It is often successful for a while, or at least enough time to allow the dogs to become accustomed to one another and to relax.


Epilepsy and Tremors

Epilepsy, shaker disorder, central motor seizures and many other neurological disorders may cause dogs to chatter teeth.

We often think of seizures as causing our entire human body to shake however they can affect only one region as well. In most cases seizures, tremors and seizures are only affecting the jaw and cause teeth to chatter.

To determine if teeth chattering is a sign of neurological issue Try to engage your dog’s attention during your chattering incident. If you can convince him to stare at the person in front of him and “snap out of it,” it’s not likely caused by seizures.

If your dog is completely unaffected by your voice or touch it’s likely that he’s suffering from seizures. Consult a veterinarian as soon as you can to get treatment.

Old Age

As dogs age, their bodies deteriorate in various ways. They might lose control over their legs or bladder, bowels and jaws.

When jaw control is compromised the teeth chattering gets more frequent.

Older dogs are more vulnerable to injury and illness which may result in teeth chattering due to the pain.

In the event that your dog has become older dog and starts to chatter his teeth, consult an animal veterinarian in order to eliminate any possible medical conditions. If there’s no evidence of any there’s nothing to worry — it’s simply an inevitable consequence of aging.
