My 23 year-old Arabian mare discovered a new way to injure herself. I discovered just a few days ago this horrifying heel bulb injury and searched every inch of the one acre dry lot pasture for anything to explain this. Then a couple days later, she has the same thing but not nearly as bad on the other hind foot. Then I saw the tufts of hair on the non-climb pasture fence where she has been leaning against the wire fencing to rub her butt. The wiring is now stretched. She backs into the fence and when she does, her hind feet get stuck under the bottom of the fencing. When she steps forward....rip! We are putting boards across the bottom of that section, and I will be putting up hot wire later. My vet saw the photos and has instructed me to keep it bandaged and use antibiotic ointments. The fun never ends. The initial injury complete with flies and hanging chunks. Today after just a few days in the bandage. The hanging chunk is reattaching.
