I'm slightly weirded out by his coloring. He looks like a Belgian mule (his muzzle appears to have been dipped in white) and has pink skin over his whole body. His eyes are also incredibly dark, but they appear navy from certain angles. The pics below are the best I have of him at the moment, will update the thread when I go out and get better angles.
This one is too big to post in the forum, so here's a link.
Does that look right? I'm a chestnut/black/bay breeder, never had a sorrel before.
