My trainer told me it was probably just ruffled up hair, because it smooths out when he sweats.
However, the other day it looked pretty nasty. (It was wet, with black goop)
No hair is falling out. The skin underneath isn't scabbing or red. But it does look a little bare.
He wears a blanket most of the time. It shows up when he wears it, and when he doesn't.
I really don't know what it is, or what to do.
I can't bathe him because it is below freezing here.
I've never dealt with this before,
Any help is appriciated
