Perhaps not because he's all beat up. The picture is too small to tell if it's just scar tissue without fur. Looks like has black skin. Lab, no, head and chest would be wider and rounder. Either american working farm dog (no consideration given to coloring) or some sort of hound mix.
I got him from a pound, they said he was white GSD, but I disagrees cause he had yellow on his back and round snout. He was very skinny when I got him... And skittish
