I've doctored much nastier cuts then she has now. There is literally nothing a vet could do at this point that I can't. The swelling has already disappeared and the dressing is being changed daily, to keep a close eye on the wound. We'll be starting with an anti-fungal spray by tomorrow.
I actually have a cream I got from my vet when dealing with a wound very similar that helps prevent proud flesh. I will try to locate it tonight and see what it is called. It was part of the reason I originally suggested a vet since wounds like this are tricky to heal. But..... You knew better.
