Itchy spot -- like mud or callus but not
My TB has a spot on his belly on the left side (actually two places very close about the size of half dollars, but not really round). It feels like stuck on mud or kind of a callus, but it doesn't come off or bleed or anything. It's kind of the color of mud. When I rub hard on it with a stiff brush, my horse LOVES it. This is not a horse who's ever liked being scratched on the stomach. Any ideas to what it is? Not bloody or anything like sweet itch or the ochin-yada-yada stuff.
Doesn't seem to bother him. It's been there for at least four or five days.
I've put Corona on it a few times because it seems as if it'd be soothing.
