Is it possible for a horse to have forelegs that are camped out and hindlegs that are normal or vice versa? In other words, if one pair of a horse's legs are camped out, must the other pair be camped out as well, or can the pairs be camped out independently of each other?
Yes and no. Whether or not a horse camps out on the hinds generally has to do with the angle of certain joints and the length of certain bones. Normally, a horse that camps out on it's fronts but not it's backs is exhibiting what is called a "founder stance", though it may not actually be the result of founder. Basically, what that means that the horse is likely experiencing some sort of pain on his front end that is making him shift his weight onto his hind legs.
