Hello, I have an old girl, close to 9 years old. She was limping and I took her to the vet. He said "arthritis" and gave her metacam. She has been on it for 2 months and it really helped her. the vet won't refill her prescription without another exam and xrays plus other tests. I would rather not do this and don't know what to do now. any suggestions? I don't want her to suffer but at this time I don't have the funds for extensive tests. I'm sad but in a bind.
