I just bought a horse, Casper, that is going to need some help with his joints. He's getting a bone spur in his right front fetlock, and there's a little (nothing bad) wear on his hocks. He's 11 and has been used as a hunter/jumper horse. I plan on continuing this use. He just had a joint injection for his fetlock, the first one, this past December. He is almost 100% sound on it now. There has been little to no change in the joint in the past two years.
I want to manage these problems. What kind of supplements should I give a try? And what else can I do to manage this and keep him as comfortable as I can?
