From what we can tell by looking at Tim Tebow's dog, he appears to be a grown boy who has taken to his name 'Bronco.' You ever owned a dog? By six months the dog's name is the dog's name. Not changing it. Want the dog to come in after dropping a deuce? Call his name? Angry at the dog for dropping a deuce in the hallway? You scream his name. Tim Tebow is changing all that in a purely Tim Tebow kinda way. JUMP!
