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.
