Hi all. We have a 4 year old Golden Retriever/Shepherd cross (looks like a Golden). She's a little fat but otherwise has always been in good heath. About a week ago we found a round sore on her back slightly larger than a quarter. It was a little infected and scabby so we rinsed it with peroxide and put some neosporin on it. It looked like it was healing up so we didn't worry about it. She'd been crawling under the porch so I thought she might have cut herself or gotten a bite of some kind. Well, now she has two more. One about a half inch from the first and the other about 7 inches farther down her side. The old one is pussing up again and I the others have obviously bled. I have no idea what is going on with her! We don't have ticks here, seldom have fleas (and I would have known if there were fleas b/c the other animals would have it) and I haven't noticed any mites on the ducks and chickens. The only thing out of the ordinary is that she follows the chickens around when they are outside and eats their poop (gross, I know). We're taking her to the vet today, but I'm wondering if anyone has any ideas what it could be?
