My 2 year old beagle/sheperd/boxer mix named penny has bad hips. She has ever since she was proble 5 months old. Alot of times she limps and holds her back leg up. Whenever this happens I always try to rub her hips. It usually helps her. Is there anything that I can do to make her comfortable? I have talked to the vet about her hips and he said to get x-rays. Except the x-rays are really expensive. Tonight I was rubbing her hips for her and I could feel her hip jerk. Like it came out of its socket. Is heat good for her hips? Or cold? Thanks.
