Well, I hate to say it, but this guy has me stumped. Look at all three pictures, including the head-shot, and give me your guesses.

Not only don't I know what breed this guy is, I can't even think of a good name for him.

Look at that face. Is he sad? Is he glad? I don't know, but as the man said, he's undoubtedly cuddly.

Another angle, giving you an idea of the snout length. Goofy pup.
I think he’s definitely got some boxer or bullmastiff in him. I can’t quite tell how big he is from the photo.
