Why do dogs chatter their teeth after licking?

There are many reasons why a dog may be chattering its teeth. The reasons can be innocent enough not to require intervention like the urge to mate, feeling excitement or joy, being over-stimulated, etc. However, the chattering of teeth can be a symptom of other severe conditions that shouldn’t be ignored if you want your dog to stay fit and healthy.

Behavioral Factors

On many occasions, dog chattering their teeth is triggered by some behavioral factors, in which they experience something or react to something. A few of those are:

Tasting something delicious

Did you just treat your dog with his favorite snack after he behaved well in front of the guests? If you hear your dog chattering its teeth, it is to show that he finds his food delicious. Dog’s senses are more robust than humans, so if they find something tasty, they tend to chatter their teeth in response. Whenever you hear the peculiar noise from your dog, look around for its favorite snack nearby, and there’s nothing to worry about.

Reaction to pleasant scents

Dogs have millions of scent receptors, almost 300 million; humans don’t even have half of that amount. According to a study, smelling delicious scents or aromas tends to activate the pleasure centers in a dog’s brain. Their strong sense of smell helps them to determine things the most than any other means.

Hence, when a dog smells something that it likes, its favorite food, human companion, or another dog, it reacts by chattering its teeth.

They want to mate

In dogs, the relationship between pheromones and mating is straightforward. Female dogs release these pheromones through urine in an environment that urges male dogs to eject their sex cells. If your male dog is chattering its teeth, it has likely picked up on the scent of a potential female canine nearby.

Emotional factors:

Just like humans, dogs feel various kinds of emotions that make them chatter their teeth. Most of the time, this reaction is harmless. However, it should not be wholly ignored. When your dog is emotionally overwhelmed, you may observe them chattering their teeth; here are a few situations that are likely to happen:


Just like we may get jumpy when we’re feeling excited, excitement can cause dogs to chatter their teeth. They can get excited about many things, such as seeing their favorite food, reuniting with their owner, seeing someone familiar, meeting a partner, or playing. These canines chatter their teeth because they can’t handle the excitement.



Dogs often chatter their teeth when they are in a joyous mood. You may be taking them out to a park where they can play and socialize with their other canine friends.

They are happy, and chattering of teeth is an impulsive behavior, so there is nothing to worry about.


One of the most common causes of teeth chattering in dogs is when they are distressed. It may be because of a loud hostile home environment, loud noises like fireworks and vacuums, or even another pet’s inclusion in the house. They chatter their teeth to show their frustration.

Fear of another dog

When a dog is surrounded by a large number of other dogs or even a single large dog, it gets scared and chatters its teeth. Chattering teeth is also a source of communication for the dogs, so they may do it to tell the other canine that they aren’t looking for trouble. Chattering teeth due to fear can be seen when you take your dog to a new place like a park, and it gets surrounded by dogs it isn’t familiar to.


Arousal in dogs is how your dog responds to the events occurring from the environment and you. Negative and positive triggers of arousal may include:
Seeing a dog that they are not fond of

Agility run

Sensing a potential female around them, and more
During such instances, dogs may start chattering their teeth.

What are the health issues that might cause chattering of teeth?

Sometimes, however, dogs chattering their teeth can be a reaction to something a lot more grave than excitement or distress. And that is some underlying medical condition. Several different medical conditions can cause the teeth to chatter impulsively or involuntarily. Nevertheless, even if you’re uncertain about the situation, it is best to plan a visit to the vet just to make sure everything is alright before the problem may get worse.

Advanced Periodontal Disease

One of the most common medical condition that causes the dog to chatter their teeth is “Advanced Periodontal Disease.” It is a gum infection where bacteria grow in the small gaps between the gum and teeth. If not given serious medical treatment, the disease can increase, affecting the dog’s bones, teeth, and tissues. It is excruciatingly painful for the dogs, and urgent treatment is required.

Often dogs try to mask this condition in front of their owners to appear healthy, but once the pain surfaces and are unbearable, the chattering of teeth is inevitable. Inflated gums might be an indication of the disease. Regular dental checkups are essential for time-to-time inspection so that the specific treatment can be started when necessary.

Neurological Disorders

Neurological disorders in dogs affect the three main areas – the brain, nerves, and the spinal cord. Dods chattering their teeth might as well be due to some neurological condition. Some of the neurological disorders that stimulate this behavior include:


Epilepsy is a common neurological condition among dogs. It can be a symptom of various things like allergies or tumors. Dogs having epilepsy have to suffer from intense shaking in the whole body. Chattering teeth is typical behavior in this condition. It may also be accompanied by foaming in the mouth. If anything like this happens, rush your dog to the nearest clinic and get it checked.

Multisystem Neuronal Degeneration/ Shaker Syndrome

Multisystem Neuronal Degeneration, also known as the Shaker Syndrome, causes your dog’s whole body to shake, and it may result in your dog chattering its teeth. This condition affects balance. Primarily, it is a hereditary issue that affects breeds, including Maltese, Bichon Frise, and Cocker Spaniel.
This condition has no cure, but the vet can treat it. They’ll use a variety of methods that help manage convulsions and teeth chattering.

Focal Motor Seizure

This condition affects the jaws. If you aren’t watching your dog closely, it’ll probably slip past your eyes. It causes the jaws to tighten up for a short period which results in involuntary chattering.

Fortunately, it doesn’t last long and is nothing to worry about. However, a checkup by the vet would be advisable to see if it isn’t the symptom of anything else.

Old Age

Old age comes along with many drawbacks, even in dogs. The chattering of teeth is often witnessed in older dogs. If they don’t show any symptoms that suggest otherwise, it might be just because of old age. This behavior can affect any dog breed after it has reached a particular age.

You must pay close attention to their behavior and understand what is stimulating it. You can also consult the vet to recognize your dog’s health situation better and get the necessary treatment promptly.

Temperature changes

Much like humans who start shicering and chatterin their teeth when they’re cold, animals use the same actions in similar situations. If your dog is chattering teeth in cold weather, it may be because it’s feeling cold. It’s best to take him somewhere inside and make sure to keep them warm and cozy.
