Jack can't jump!
We have a 6 yr old Jack. A couple of weeks ago she went crazy when the next door neighbor kids were in the backyard. Now she can't jump up on the couch, etc... and occassionally holds her left, rear leg up. Vet can't find anything on the X-ray. When she is given pain pills she thinks she can run again. We are trying to control her freedom by tying her up and helping her up/down from furniture. She hasn't been her normal perky self... Vet said if it doesn't heal we might need to go to a specialist. He thinks it could be a nerve... Any ideas?
