My dog injured his left hind leg after jumping and falling on the wooden floor two weeks ago. We took him to the vet the day after because he was limping, but x-rays didn't show any fractures or dislocations. The vet told us there was a possibility of a hip joint disorder but would need to perform further tests to confirm. Right now it has been a week with painkillers, and he still doesn't seem to be able to put his full weight on the leg - his energy levels and appetite are normal. We've been giving him specialty food and supplements that are said to help with joints. I would like to avoid surgery, but my biggest concern is that we sometimes hear his hip joints clicking. Please give us your thoughts.
