Eight beautiful pit bull puppies were recently fathered by the world’s biggest pit bull, Hulk. Owned by Marlon and Lisa Grennan, founders of Dark Dynasty K9s in New Hampshire, USA, the dog is being trained for protection services. Hulk pit bull puppies, if also trained to be elite protection dogs, could fetch up to $55,000 per pup.

“Their papa isn’t a legend for no reason but the potential to have another record-breaking world famous dog amongst his puppies is there,” Mr. Grennan told Daily Mail. “Most of them are already sold. That’s just how well Hulk’s pit bull bloodline is thought of.

“Dark Dynasty K9’s is a breeder specializing in protection dogs. Marlon trains each dog personally from birth, and the dogs live together in a pack “without fences, barriers or physical restrictions.” The dogs are so well trained that they are even permitted to interact with the Grennan’s three-year-old son, Jordan. And while a ‘cute pit bull’ is not the most usual description to this breed, just look how sweet Hulk is with is puppies.
