I just noticed today that Kima has a lump about the size of a golfball on her rump to the right of her anus about an inch to two inches from it. This is something that was not there two days ago (I didn't notice it yesterday either but I can't be for sure it wasn't there as the day was very hectic). I was wondering if anyone had any suggestions they might want to give? My vet isn't open until Tuesday and I was wondering if it would be safe to wait till then or not. I would take a picture of it but you can't tell she has this lump in any of the pictures I have taken. It's not affecting her play any. Oh and she is also coming out of heat (don't think that would have anything to do with it but I'm trying to give all the info I have at the moment).
