I've had a few people accuse Mr. Jennings of being a pitbull so I googled pitbull puppy pics and found this.
And another Pit of similar color.
I can't hardly get him to stand still but he looks an awful lot like the above dag
Lab pup for reference.
His ears were the one thing that made me think he wasn't a full blown lab but after seeing these pics I think he might be a Pit. He is awfully aggressive it seems.
