Memphis hurt his knee a little over one year ago. He was never fully lame and I didn’t take him to check it out at the vet for 3 months, thinking that it would for sure improve. I have had 3 vets tell me that he probably should have surgery but am not really sure. I am worried I waited too long, or that we have too many stairs for a good recovery, or that he might still get better. There have been weeks of definite improvement but ultimately I would say he had a bad knee. It seems like his hips are kind of weak these days too. He is a very happy playful guy and 4 years old and getting a little bit lazier. I genuinely don’t know what to do. Please help!
