@ellymayrans Once you stop the bleeding and clean up the wound with a disinfectant, if a lot of neck skin is missing, make what's called a wet - to-day bandage. Basically this is several layers of gauze over an antibiotic ointment (Neosporin, for example), of for the naturopaths, a thick layer of natural honey. Honey has great properties and I've used it in practice. First layer of gauze should be damp but not dripping with sterile saline. Ask your pharmacist, but you can possibly use a saline eye wash or nose moisten in product. 2nd layer of gauze is less wet, 3rd is dry. Wrap with some Cling wrap and tape, or Elastic on horse wrap and tape. Change daily to no more than 48 hours. You will see pink granulation coming within days. Once the gap is totally granulated, skin will start to regrow. At that point, you can just use ointment/honey and a dry wrap every 1-2 days until the skin is all back. Hope this helps!
Poor guy! I just hate it!!
