I don't know. His front legs seem fine to me, but I have noticed him resting his back feet a lot this past week. He is also touchy when I pick his back hooves, but not his front. He was touchy about his back hooves when I first got him---some lady had bought him before me, and had him for four months. She didn't feed him right, and he dropped about 100 lbs! Her kids had also been allowed to mess with him, and were pulling his ears, and he was touchy about his ears for awhile, too. He now lets me do anything with his head, and he had been a lot better about his feet---I guess she didn't treat him right in that area either. He's come a long way in two months, and is such a sweet horse. Why do so many people mistreat these animals?
Everything can be achieved through patience!
I'd rather have a problem horse than a problem man. The horse I can work with. The man---I cannot help!
