I saw this in Reesie before she had LP surgery. The vet told us that the inablility to walk properly put a strain on her back and she would arch and even stand on her front feet, like a handstand, just to eat. She would yelp for no reason, and the shivering is a sign of pain. Whatever the cause, Roxi is in pain, but I would have her knees checked first by a COMPETENT orthopedic vet. Reesie's knee problems showed up when she was about the same age as Roxi, but not to the severity that developed later. |
