Hello, this is our 12 year old German Shepard mix. She was in a lot of pain, guarding her leg a lot, limping, the whole nine yards. The vet said they didn’t see any breaks or sprains. The ortho surgeon said there might be a mass on her pelvis when they did more x-rays but we are waiting on a MRI. About 2 days after her hip x-rays she seemed to loose all feeling in her leg. No more pain, her legs was just limp. Well now we are concerned about swelling happening. Still not in pain, but major swelling happening. Anybody have any idea what this may be?
