‘He Is The Perfect Babysitter’: Hulk The World’s Biggest Pitbull 168lb.

He might weigh 168lbs and have a fearsome bite, but the world’s biggest pitbull is the perfect babysitter for a newborn baby, according to his owners. Marlon and Lisa Grennan, from New Hampshire, let world-famous Hulk lick and watch over their three-month-old boy, Jackson. It is not the first time the couple have done this, as their eldest son, Jordan, grew up with Hulk and other American pitbull terriers who live at the family home.

Lisa, 25, said: ‘I have no worries with Hulk being around the baby. It’s not a big deal. ‘When we brought Jackson home Hulk was all over him. He was watching me while I cared for him and he would go and check on him when he would cry. ‘He is the perfect protector and babysitter. He really does love him and you can see it in his eyes.’

Marlon’s company Dark Dynasty K9s specialise in training elite protection dogs for the police, celebrities and billionaire clients around the world.

‘When you’re the leader of that pack and there’s structure, rules, boundaries, limits and leadership, then there’s nothing to be worried about. I’m always in control.’ said Marlon
