Thanks for your posts!!! Nicholas has an appointment on Thursday. Dr. Ascher was out of town, and I would like her to check him out. Jen, I have no idea what this could be! I did some reading in books and on internet, but could not find anything that was like what I saw. It must have been itchy, Nicholas scratched it, and now there is a scab, but can see the base of whatever it is. Thanks for your concern, will keep you posted after the vet visit.
