Hi Leel,
I know this is a very old post but I just wanted to see if you were still around and had an update on results of the neuro?
Our basenji cross, Indy, started doing teeth chattering out of the blue this morning after every yawn. She is female, C. 1 year (we're not sure exactly as she was a street dog).
We took her to the vet this morning who also didn't have an answer but doesn't think it's a seizure because all other responses seem fine but I'm freaking out a little. The vet gave us some pain killers to try in case it is something in her mouth but she has had no trouble eating and chewing on bones so this doesn't seem likely. She also didn't seem to be under any undue stress, just tired from sleep in the morning so yawning a lot. Having said this she seemed mopey and didn't come on out bed like normal in the morning so not sure if this points to it being emotional... She seems to have gotten better throughout the day and didn't do it after yawning just now but not sure if this is related to what the vet gave her.
I'm very worried as some posts have been talking about it being normal (mostly in males) but in some posts it has been a neurological disorder which has gotten worse.
Any advice would be greatly appreciated.
Thanks in advance.
Susie
