Riley is developing a touch of arthritis in his back and his left hip. Every now and then when he gets up (mainly first thing in the morning) he has a bit of stiffness. My vet (who I do trust) suggested putting him on Rimadyl. I'm very uneasy about doing that and would like to try a safer more natural approach. He's also taking Sota now for his heart so I'll need to make sure whatever route I go will not clash with the Sota. Do any of you have any suggestions?
