He's a mutt. Belgian or GSD mixed with some guess Pit, some guess lab, and something tall, for sure. The top of his head is boxy and his chest is thick like a pit, but his snout is tapered like a shepherd and his body is taller and lankier than a pit.
I posted a while back asking for guesses.

This was taken about a month ago. He has since gained 11 lbs and is taller.
I am going to have to get back in shape and start running again I think.
