Well, in the course of having acupuncture for Asta's head tilt, a residual of her vertigo attack, the vet who does that treatment discovered Asta actually has a problem in her neck. She doesn't think it's a disc problem, but feels like a bunched up muscle, perhaps also a pinched nerve. So her funny gait is actually more likely from that rather than the vertigo! She had two acupuncture treatments and now is having cold laser therapy focused on her neck. Today both the vet and I said her head is definitely straighter! So working backwards, since all symptoms are from her Feb. vertigo attack, we figured out she may have tweaked her neck in the throes of having the sudden severe vertigo attack. My husband had left her two hours before he came home to find her on the kitchen floor unable to get up. We think she may have thrashed around and done something to her neck at that time, since she's never had any issues like that before. Good grief, if only the darn dog could talk!!! Would take the detective work out of the equation! We are hoping that this will help her movement get back closer to normal. I realize she is 12 1/2 but since everything happened so suddenly, I don't think it's just her age. So what I thought was a balance problem is likely something else entirely. SIGH.
