Hank is a large puppers with a weight of 220lbs. This past fall he was hobbling at times and could barely walk, due to a problem with his right shoulder. We started him on the cartilage, hip and joint formula, it has worked miracles for him. He is now back to chasing his ball, going for walks and going up and down stairs without issue, etc. He is back to enjoying life again. He takes it every morning faithfully. I believe it has literally saved his life.
