Remember in the original Rocky when Adrian gives him Butkus the dog, so he can have company when doing his roadwork? As part of the training for his title bout against Apollo Creed, Rocky pounds the pavement in the streets of Philadelphia with his faithful bull mastiff.
But Butkus never showed any (or maybe he just wasn't given the chance) boxing skills. And that brings us to this dog, who is apparently a very determined shadow boxer. Or shadow stomper.
