have your vet x-ray his spine. My Pepper does this and it is caused by some bad disk in his back...doesn't have anything to do with his legs, although it effects his legs. It seems to be worse after he has had a bad episode of back pain. This may not be the case with your chi, but it is worth looking into. Marsha

I had my vet examine her a few months ago regarding floating patellas and he said he couldn't feel anything. Do they all run like this? I notice she walks kind of strange on grass but I always figured it was the grass rubbing her belly. Michelle & Twinks
