At 175 pounds, he definitely lives up to his name, and may be one of the largest pitbulls in the world.
The Hulk and his owners, the Grennan family, are the subjects of a new short film.
Marlon and Lisa Grennan have no problem letting their 3-year-old son Jordan play with the giant animal, including riding on his back. That's because Lisa says The Hulk and their dozen dogs are properly trained.
"The regular things that a kid might do to startle a dog isn't going to faze our dogs at all. They're amazing family dogs."
The Grennans run Dark Dynasty K9s, a company that breeds and trains security dogs. Marlon says he is very selective with the clients he sells too.
