I had a horse one time that cut her front foot, right above the hoof, on some barbed wire. When it healed and I started riding her again, she would start limping after a short ride. I would put her back in the corral and get another horse, until one day I noticed that she was limping on the wrong foot. I made her go on and she quit limping. Never tried it again. I haven't figured out if she was smart or dumb. miles
