What do we do? She had a real big abscess on her chest when we got her which was 2 weeks ago. The breeder said it was from her vaccine injection and she and many other people told us not to worry about it. Right now as I type she is leaking pus from the abscess. Most people said it would slowly get smaller and smaller not bust open. Do we leave it alone and let it drip or should we do something about it?
