Good observation Jack. His previous owner was feeding him less than stellar food. He's been eating Orijen Regional Red and Orijen 6 Fish for a few weeks now. HE LOVES IT. So he is definitely on a better plan now than what he used to be. Some of the missing hair is from Day 1 of the show where he got loose and went at it with Machobear. I broke them in a flash, but when we put him back in his kennel he went nuts and chewed through the air holes and was able to get his muzzle and head out of tiny hole he made in the kennel. In the process though, he scraped his face up pretty bad.
