My Chihuahua has what appears to be some sort of rash on the middle/center of her stomach that goes down the sides of her stomach and part way down the insides of her back legs. It is brownish in color and is kindof crusty, almost like a scab (might be hard to see in the pic). It doesn't seem to bother her, every once in a while she might try to scratch it, but doesn't seem to be a big problem. It started very small on her stomach a few months ago (and just looked dirty) and gradually got bigger (baths don't seem to make a difference). What could it be? What should I do about it?
