Is this really true...?

That horses are considered livestock, and therefore owners don't technically have to have their feet done? a man in a neighboring city of mine has 6 mares and a stallion. all of them are lame as hell, and his big fat greasy white wife and her friends run around on those poor horses. I was invited there because he was having a "race" and I went to check out his horses - they all had awful feet, swayback and were skinny. His stallion was hidden in a makeshift "stall"if you could call it that. I confronted the man and he said all his horses were taken care of and in great shape. We left and called the game warden, who said he'd been out there before....but I mean. what else can I do?
