Aj K, I used Derramax years ago because I had a lab mix and knew the issues with labs and Rimadyl. Even though I used small occaisonal doses and was careful, it did a number on his liver and ultimately his kidneys. The adequan is a very good choice and I realize the dog is senior, but Tramadol (more of a morphine like based pain killer but no damage to liver or kidneys) might be a better choice. We switched to that when the kidney failure set it. Fish oil supplements would be helpful and Dori offered some supplement suggestions that could be useful. Good luck with your baby!
