Why does my 10 year old spayed female dog chatter her teeth every once and a while?

I think that is some kind of mini seizure. My Border Collie/Sheltie mix (also female/spayed) used to do the same thing. The vet never knew, but I have found out since then that some vaccinations are thought to be the cause of seizures in many dogs, sometimes appearing as they age. It was a very mild thing, and the vet told me not to worry about it. Hope this helps.

Dogs chatter when they smell something interesting. It pulls the smell across the jacobs organ in the roof of their mouth and allows them to get more information from the smell..
Reply:I have several dogs who do this. Some dogs do it when they get ahold of a good "scent"- like, my male does this when he smells a female in heat. He also does it, however, if he gets a good whiff of my spayed female.





I have another dog who snaps his jaws when he's happy.





I wouldn't worry about it, unless it seems to be tied to something else that might make you worry.
Reply:some dogs do this when they are nervious its like a tick that they do every now and then others do this when they smell things from other dog some times dogs grind their teeth as well when they are in pain i suppose it would depend on the situation and what ur dog is doing when it does this and where its at alot of the borders at the hospital do this when they are nervious
Reply:Most times this behavior is seen in males when they are scenting a female for breeding receptiveness.


They are dragging the scent over a gland in the roof of their mouth that is very scent sensitive.


Or I have seen dogs look at a person and chatter their teeth.


In that case the ones I have witnessed doing it were showing submission to their owners.


I had a female dobe who used to do it to get your attention. She would stare at you then chatter her teeth while looking at you.
