Don't laugh, OK?

My dog, a six-year-old golden retriever, developed pain in back/hips that made it tough and painful for him to move. Vet suggested glucosamine complex before more expensive/extensive attempts at solutions. After a few weeks, it slowly improved, and now he's back to normal, and we keep him on a maintenance dose. My understanding is that this stuff was originally USED successfully in animals, and we're just catching on. I also had difficulty finding unbiased info, but my dog is pretty impartial ; )
