One of my horses got her neck cut up somehow the wound was about 4 inches high and 2-3 inches wide. The cut itself had huge pus deposits around it and I was really really worried that it woudn't heal and she'd develope some sort of blood infection. I used a liquid spray twice everyday for two days, then switch to a powder like Wonder Dust. This was a really big cut. It's almost completely gone and it's been about a month and a week since it happened. We used peroxide to irrigate it, but never leave peroxide on the skin. You have to clean it off with water. Whenever my horses get abscesses, we tie up the whole hoof up to the fetlock with duck tape and vet wrap and change it daily or every two days depending on the weather conditions. If you're going to wrap it up, check it everyday. Sometimes it's better the cuts to air out.
