my 4 week old campine has a lump between her legs. it has been there awhile and never bothered her. i posted awhile ago and we think it might be the umbilicus but i don't know. anyone got any ideas? here is a picture from about a week ago

Appears to be a small hernia. I'd leave it alone as the more it's messed with, the more damage could be done. Otherwise, I don't think there's much that can be done to help her. A vet "MIGHT" would put a stitch to close up the hernia, but I'm doubting it.
