You know what astonishes me? I've been around a lot of horse shows and horse show people now. Some of the paint Quarter horse yearling had more muscle then my clydesdale cross yearling filly. Those people give their show horses steroids! I would have never guessed since I just assumed humans did that for vanity! What people do for competition sake! I was taken aback once I actaully was told that, although I assumed they were doing something to make them massive i wasn't quit sure.
