The wound looks very serious to me. Do not use BluKote since it is for minor scrapes, not deep infected wound. Vetericyn is good, but I would get some chlorhexidene or Hibiclens at your pharmacy. Dilute it with water to 2% and rinse with water. That is a hospital approved disinfectant where infection is concerned. Once it looks and smells better, you can use the Vetericyn again twice a day. Vetericyn Hydrogel is a very good product if you have that. Is she able to stand and walk around? How is she eating and drinking?
