See ..Hulk the world's biggest pit bull is 12 and a half stone - and STILL growing

Proud owners of the world's biggest pit bull dog have told how their three-year-old child rides the 175lb pooch like a horse. Marlon and Lisa Grennan from New Hampshire say their monster pet 'the Hulk' is 100 per cent trusted with their son, Jordan, despite the breed's fierce reputation. Indeed, photographs show the toddler happily riding on the canine's back, grabbing the collar just behind its 28-inch wide head.
