Right now it just looks like a small blemish [ like a pimple for a human ] that came off. You can watch to see if the area stays the same or another small growth appears.
I agree, keep an eye on the area to be sure another growth doesn't crop up again. As suggested,
continue to use raw honey or silver gel on the area to help it heal up.
Yea it has anti bacterial and then tonight it's honey I switch it every couple days it's been helping alot so far. Well as much as I can through a camera
