Why Does My Dog Chatter His Teeth?

The phenomenon of teeth chattering is very common as dogs shake their heads. The sound of chattering teeth can be very familiar if you own a dog. Your dog can chatter his teeth for lots of reasons. 

On a large scale, these reasons can be divided into three categories. We have discussed all the categories here for your better understanding. 

Reason 1: Physical Causes 

Several physical problems or discomfort can make the dog chatter with its teeth. Look at some significant causes below.


Almost all types of animals shiver in cold weather. Even human beings chatter with their teeth in too-chilled temperatures. Though your dog has a layer of fur, sometimes it is not enough.

There are lots of benefits to having small dogs. The body temperature of the dogs can fall quickly due to cold weather. But if you own a small dog, the possibility of chattering due to cold increases. 

A temperature that’s moderate to you can be uncomfortable for the dog. And then he will chatter his teeth.


Dogs are always jumping and playing. Many times they hurt themselves while doing such naughty things. But dogs are unable to express their pain through words. For that, they use chattering noise as a sign.

New Smell

New and unknown smells can also make dogs chatter with their teeth. Dogs smell everywhere by smelling around; a dog makes himself familiar with the environment. 

Dogs have a vomeronasal system for conveying more information from the smells. This system can affect the dog’s face when smelling a new scent. And as a result, teeth chattering starts. This is normal for a dog.

These are the physical causes for a dog to chatter with his teeth. Now let’s go through the mental reasons.

Reason 2: Mental Causes

Dogs also have feelings like human beings. These feelings have effects on their brains which cause reactions. A dog can chatter his teeth due to these reactions.


Anxiety or fear is a prime reason for chattering. Several animals, including humans, chatter teeth in fear. Your dog can do the same too. Fear of a new place, people, or environment can make the dog chatter.
