Look into DR Underwood horse medicine. I've never had a need to use it on a dog but it works wonders on horses. I assume if is safe for dogs. We used to keep a case on hand for horses. It is the only thing I have seen that would allow the hair to grow back on a bad wound.
My cousin told me about this and he gave me a bottle of it last night. He thinks she's done for the year. I really hope not because she was hitting on all 8 cylinders lately.
