Why is My Dog’s Jaw Chattering? Understanding the Cause.

Dog owners may have noticed their furry friends chattering their jaw at times, and it can be a worrisome sight. Is it because they are feeling cold or nervous, or could it be due to a medical condition? Let’s dive deeper into why dogs chatter their jaw and understand the underlying causes, symptoms, and treatment options.

What is Jaw Chattering?

Jaw chattering, also known as jaw quivering or teeth chattering, is a rapid movement of the lower jaw that makes a clicking, chattering sound. Dogs may exhibit this behavior while awake or asleep, and it can last for a few seconds to a few minutes. The chattering may be visible, or pet owners may only notice the sound.

Why Do Dogs Chatter Their Jaw?

There are various reasons why dogs chatter their jaw, and each case is unique to the dog’s behavior and surroundings.


Dogs that are feeling cold may shiver or tremble, and jaw chattering may also be a result of the dog’s body temperature dropping. Small dog breeds, dogs with short hair, and those with a thin coat are more susceptible to feeling cold and may chatter their jaw as a way to warm up.

Nervousness or Anxiety

Dogs that are nervous or anxious may display a range of behaviors, including jaw chattering. This behavior may be accompanied by other nervous gestures like pacing, panting, and whining. Separation anxiety, fear of loud noises or unfamiliar people or animals, and travel anxiety are some common triggers for jaw chattering due to anxiety.

Medical Conditions

Jaw chattering may also be a symptom of underlying medical conditions. Some of the medical conditions that can result in jaw chattering include:

  • Epilepsy – Dogs with epilepsy may have seizures that are accompanied by jaw chattering or teeth-chattering
  • Dental issues – Tooth pain or tooth decay can cause jaw chattering as a sign of pain or discomfort
  • Neurological issues – Neurological problems like neurological damage, nervous system diseases, or trauma may result in jaw chattering
  • Fever – A fever can cause your dog to chatter its jaw or teeth to chatter in the same way humans do

When to Consult a Vet?

If jaw chattering continues for an extended time, you should immediately consult your veterinarian. A vet will be able to identify the underlying cause of the chattering and guide you through the appropriate treatment options. For instance, if the chattering is due to a medical condition, the vet will provide medication or recommend a surgical intervention. Moreover, if the chattering is due to anxiety, your vet may recommend training or behavior management techniques to alleviate your dog’s anxiety symptoms.

Treatments for Jaw Chattering

The treatment for jaw chattering varies depending on the underlying cause of the behavior. Here are some common treatment options:

Medical treatment:

If the vet suspects a medical condition, they may recommend treatment options like oral medication or surgery.

Behavioral modification:

For dogs with anxiety, training and behavior modification techniques like crate training, pheromone therapy, or anti-anxiety medications may be necessary.


Therapies like acupuncture, massage, and physical therapy can also help alleviate pain, discomfort or improve circulation.

Preventing Jaw Chattering

While some cases of jaw chattering are unavoidable, pet parents can take some simple steps to prevent their dogs from displaying this behavior again:

  • Keep your dog warm and comfortable with appropriate clothing or warm blankets, especially during cold weather
  • Avoid exposure to high-stress situations or stimuli
  • Visit the dentist and schedule annual check-ups to ensure there is no oral pain or discomfort
  • Exercise regularly
