A bully pitbull that's almost the size of a miniature pony has become an internet sensation after his owners released photos and videos of him online. Aptly named 'The Hulk', the impressive canine weighs a massive 173 pounds and he is still growing at only 17 months, The Hulk is already three times bigger than other dogs of his breed, and he's already being hailed as the 'biggest bully pit bull on earth'. However, his owners, Marlon and Lisa Grennan, from New Hampshire, say The Hulk is a gentle soul, and even let their toddler son ride him like a horse.
