Lexie had an x ray of her shoulder and has tendinitis. Vet said to try rimadyl for a week to see if it made a difference. I only noticed very slight improvement. I will be calling the vet to see what he wants to do next, but I wanted to see if any of you guys had suggestions that worked for your greys. Any meds to stay away from? Thanks. Lexie has a very sensitive tummy. The rimadyl didn't bother her.
