This is Hulk, a 173-pound pitbull. His owner Marlon Grannon breeds and trains protection and police dogs at Dark Dynasty K9 in New Hampshire, but he has made Hulk his family pet. While he's not an official record holder, Hulk may be the largest of his kind — he's certainly a massive example of the breed.
In spite of his formidable appearance, Grannon says Hulk is a cuddly sweetheart with all of his family members. He also likes to sing! See the videos below for an example of Hulk's musical stylings, and a profile of him by Barcroft TV. Keep up with Hulk's happenings on Facebook and Instagram, and see a number of adorable photographs of him here.
