My horse seems to have a knack for injuring his back legs in the pasture. No one knows how he's doing it, but he has had scratches on the front of both rear legs, he has almost like a puncture type scratch on the inside of one of his rear ankle (hock?) and then today I went out and he has cut himself pretty good on the back of one of his front hooves, where the hoof meets the skin down by the frog. I was just wondering, is there something I can put on his lower legs to keep them protected while he's in the pasture, so he wont keep doing this? Like I said, no one can figure out how he's doing it. He is pastured with two other horses and neither one of them are having this problem.
