We recently adopted a dog from a shelter. It's happened twice now where she seems to lose control of her head. It looks like she is shaking her head no, quickly. It goes on for about a couple of minutes and while it happens, she can still walk around and act normal. Needless to say, it's a bit freaky to watch. It kind of makes me think she's having a seizure, but only her head.
We took her to the vet and they did her blood work and everything came back normal. I've seen on this forum that some people have said it could be ear mites or an ear infection. Would the fact that her blood work came back normal, refute those possibilities?
She's about 3 (she's a stray), a terrier/pit bull mix, and everything else about her seems relatively normal. The only other strange thing she does is do this low cough. It kind of sounds like a forceful exhale and it occurs infrequently throughout the day. (If someone knows what that could be as well, that would be great.)
