There is no supplement for LP, but there are supplements for the joints in general. We use Cosequin. It's a glucosamine that helps keep the joints "juicy" LOL. However if arthritis has already set in, I doubt this will help. If it gets to the point where he becomes lame, you will have to get surgery done.
