About 3 or so weeks ago we found a small bump on max's tummy area. ( If it has been longer or shorter I'm sorry it's been a little crazy here). No big deal it was very small and wasn't bothering him. Then he started licking the area. About the same time Molly started to show some interest in it just kind of sniffing it every once in a while. Bottom line it has now doubled if not tripled in size this happened in about 3-4 days. Can't get to the vet till Monday afternoon. Any Ideas?
