Pictures of the thoroughbred mare that tore a hole two inches in diameter all the way to the bone above her left hock. The vet said the horse would have to be taken to the horse hospital for surgery or it would almost certainly be infected and die. He also said it would be scarred with a sunken area and never race. It was treated by flushing the wound with tap water, then hydrogen peroxide then water again and then with ionic silver. This was done daily until healed. In Figure 1. the wound was about a month old. You can see the new pink flesh covering the bone and the wound has healed inwardly quite a bit.  In Fig 2 there is absolutely no sign of the injury and the horse shows absolutely no lameness.
