I was going to recommend acupuncture but it appears you've already thought about that. I would be curious to hear how that goes. My sister's Lab wouldn't move this weekend. They just came back from the vets and the vet think's he may have stumbled or tripped and hurt himself. He's 12 years old, has had a stroke and has bad hips. I suggested acupuncture to my sister but I don't think she's buying it.

I am sending you & Zoey a HUGE hug. I hope she gets better real soon.

P.S. Also, what about water therapy? Have you thought of that? Not sure if that would help.
