THE owner of the world’s biggest pitbull has paid tribute to his supersized canine companion - with an equally supersized tattoo. Dark Dynasty K9s founder Marlon Grennan, 31, had a giant image of Hulk, the 175lb pit bull who has taken the internet by storm, inked on to his chest. Hulk has become the figurehead of the New Hampshire-based protection dogs company and Grennan said he wanted to immortalise the canine colossus as a mark of respect for changing his life. Hulk’s size and power has catapulted him to internet stardom, with his own book deal, dog food brand and merchandising line - and regular guest appearances at dog shows. The enormous mutt recently attended a dog event in Manhattan to try out his new chunky gold collar, the ‘Midas’, made by the team at Big Dog Chains. Dog Dynasty season 2 is available on Barcroft TV’s YouTube and Facebook Watch pages, with a new episode released every Friday.
