Q. Why does my Labrador chatter her teeth before falling asleep?

Answered By

A. The most obvious reason a dog will chatter its teeth is because he is cold. But sometimes, dog teeth chattering is a sign of a behavioral or medical disorder. It's worth getting your dog checked for any underlying medical conditions just to safe and for your own peace of mind.

The most serious cause of teeth chattering in dogs is usually caused by focal motor seizures. These seizures will cause short bouts of teeth chattering.

Small dogs are best known to chatter their teeth when they are nervous or excited, but bigger dogs are known to do it as well. There is no known reason for this, but is usually not a cause for concern.

If your dog has swollen or bleeding gums, she may chatter her teeth in pain. Always check your dog’s mouth if you notice she’s been chattering her teeth out of habit.

As long as your dog does not seem to be in pain, teeth chattering is not usually a health concern. However, it is important to check your dog’s teeth regularly if he has a habit of chattering his teeth to make sure they are not cracking.
