‘Hulk,’ a massive 173.4lb (78.6kg) pitbull in the U.S., is a trained professional guard dog, who will heed his owners every command and protect them with his life. But don’t let that scare you – this gentle giant, possibly the largest of his kind, is also a big softie who loves to sing and play with his entire family.

Hulk’s owner, Marlon Grannon, says that his dog is priceless to him – though he breeds fierce protection and police dogs for a living through Dark Dynasty K9, it looks like Hulk’s place will always be right by his owner’s family’s side.


He has so far been taught to attack and release on command as well as vault and assault would-be assailants in and on cars. But owed to his balanced nature, former boxer Marlon and wife Lisa Grennan, 25, still allow him to interact and even bite-train with their three year old son, Jordan. Outside of training the pair are also best of friends and love bathing and singing together, with Jordan playing the harmonica while Hulk howls.

Lisa said: ‘Hulk is an awesome, well-balanced dog and he doesn’t get phased by the sort of things that might upset or distract another dog.
