Took her to the vet yesterday and he shaved the area. He said to apply diluted iodine 3X a day, Benadryl 2X a day, plus gave her an antibiotic. It's a pretty big area, about 3"x6". The Benadryl seems to be comforting the itching, so she doesn't seem to be in agony any longer. That said, should I still apply Gold Bond on top of all that?
