Getting that weight off is really going to help!
I agree that Adequan is a great drug-really no side effects either (their study only shows side-effects in dogs that receive much higher doses than what is given).
I also just heard about Duralactin-helps with inflammation. It's a product derived from milk. An agility friend of mine got her GSD off of NSAIDs after two months of using this product.
