My 6 year old Bernese Mountain Dog has been getting little lumps on her body, mostly on her back/neck area and one on her upper leg. She only has two or three. They're not completely circular, they're more like...hmm, like this: () like a flat circle. They're about the size of a nickel, and they're in the skin, NOT the muscle or bone. This puzzles me because they do not get bigger, they are in the skin and are not attached to any muscle or bone. What are they? Maybe some skin tags or something...?
