I have an 11 year old mixed breed who for th epast year has had these weird "spells". Everytime she eats (breakfast and dinner) she make sthis face where it i slike she is yodeling but with no sound. Almost like she is opening and closing her mouth with her head sticking up trying to swallow. It doe snot look like she is chewing gum. After 1 min she is done and acts perfectly normal.
It could be what's calle da focal motor seizure. I would try to get her to do this for your vet or even video tape it and take that with you when you have your vet examine her.
