When I took Lexi to the vet last week I had them check her legs to make sure she didn't have any problems. I had no reason to suspect she did. The vet told me the she has not quit a grade 1 Luxated Patella in her right rear leg. He said that it might not get any worse. That was all he said. I take her back in May fro some shots. I was wondering what else I should ask them about it? Is there anything I can do to try and keep it from getting worse?
