We're not entirely sure, some weird mutt mix. He's about 1.5ft at the shoulder, he has buggy eyes like a boston terrier, and a short snout with an under bite like a boxer. His legs are long and thin with long toes, but he has a round chest. His ears flop and are triangular shaped, his fur and tail are beagle like, and he's all black.
Heh, he's old and just lost an eye due to an infection, so he looks even weirder now.
