I agree with the cold hosing and the tetnus as well. The cold hosing should have started immediately. Swelling causes damage, so the less swelling involved, the better. If the cut was close to the ground, I'd bandage it to keep it clean. If the cut was gaping, and in a place where stitches couldn't be done, I'd bandage it, otherwise, I'd let it air, but I'd put furazone on it to keep it moist and not dried out and crusty looking. Flies are also another issue. I've also used bandaging to keep the swelling down to a dull roar. Hocks are hard to bandage. But if she is sore enough to lay down and rest, then those cuts are going to be on the ground, possibly grinding into the ground when she gets up if those cuts are anywhere near her pivot point on the hock. If you do bandage, do so loosely...very important. Wrapping in a figure 8 around the joint. It's another bandage applied normally on the cannon bone below the hock bandage that does the trick to keeping it on. Unless you are an expert on bandaging, I wouldn't attempt to wrap the hock, you could do more damage than good. I would however, put two bandages normally on her back legs for support. If you get a thick padding under the bandage below the injured hock, you can actually change the pviot point from the hock and put all the strain on the bandage itself when she gets up. As for proud flesh, I don't think that it makes any difference whether she is bandaged or not. It's got a life of its own and once you see it, you know that she is over the hump and healing well. It can come on fast, though, so you have to keep and eye out for it...happen literally overnight! You have to stay on top of it. I just rub the cut with my fingers and give it a good massage or even use a toothbrush or something to gently abraid the cut until I see bleeding start, then quit. You don't want the proud flesh to get the jump on you. It will disfigure things and the vet will have to come out and contour things with a knife. A couple of days and you are past the proud flesh stage, then you get the nice scab that you've been waiting for. Good luck! And please don't take the tetnus shot advise lightly, you don't EVER want to see a horse with lockjaw.....ever!
