Chattering teeth in my cocker spaniel/king charles cavalier

Question
Hello!

I've been checking with everyone I can find trying to find out if this is commmon or not. My cocker spaniel/king charles cavalier has chattering teeth. Like when kids are too cold... She did this before and I took her to the vet. They never saw her do it and ran test to find nothing wrong with her but shes started doing it again today. It seems involuntary. Any ideas why she's doing this? Is it come among this breed? Should I be worried?

Answer
Hi Karli
I am really sorry but i have honestly never heard of this, this is outside my knowledge, but im sure if the vet has done tests and all proved negative, then its likely its just a dog thing! Or rather your dogs thing, i really dont think its anything to worry about, however if you are concerned why dont you try contacting a behavourist she or he may be able to help you further.
Im sore i cannot help you in this matter and wish you the best
