Has anyone else ever seen this? We first discovered this on Scooter last April and I can't remember now what it was called, but supposedly was nothing to worry about. It was about the size of an English pea then. Seems that it has grown since then so I'm going to take her to the vet next week. Just wondering if anyone had ever seen this before. It is on her back left leg. It does not bother her for us to touch it. She does not lick or bite at it or really pay any attention to it at all.
