Brown. That's what we usually answer.
His size is deceptive, he's only about 65#, a good mid-size dog. Built like a brick $#!^house though.
Our best guess is he is 1/2 chocolate lab and 1/2 Amstaff or one of the other bully breeds. As he has matured he is more pit looking when his ears are back, lab looking when his ears are forward. And his breed characteristics of tenacity, digging for rodents, close physical contact are very much terrier like.
