If your dog is on Rimadyl have a liver profile run once every 3-4 weeks. Rimadyl can readily cause liver damage if given over a prolonged period of time. If it should start to cause problems you need to catch them early with the blood tests.

Deramaxx and Metacam both have better safety profiles. However most Vets still prefer Rimadyl- first to market, plus it relieves the pain the best.

You should strive to use the minimum dose of Rimadyl. If possible give it every other day or less often to keep the inflamation and pain under control. Definitely try the Glucosamine, although it may take several months for it to show any effect, if it going to have an effect.

Also if your dog is overweight, cut back on the food to get the weight down.
