I started reading an article in a magazine about it. I didn't get much farther than "Sickle hocks might actually be a problem somewhere else!" So I was hoping someone could fill me in. It was widely believed to be foot problems, right? But now they're seeing that it could be trouble somewhere else.
Forgive me if I sound like a moron, but at least I'm asking.
Also, while we're on it, anyone who knows good, reputable horse health books should suggest the author and title.
