My dog’s teeth chatter when he gets excited. Should I be worried?
Teeth chattering isn’t all that unusual in dogs. It’s most likely just a nervous habit, particularly since your dog only does it when he’s excited. You and your veterinarian should check his mouth for any signs of oral disease (swollen or bleeding gums, broken teeth, etc.), but if you don’t see any signs of it, the teeth chattering shouldn’t be a problem. Just keep an eye on it to make sure it doesn’t happen more frequently or become more severe.
