"Oh my God, he's so big." This is the first thought that arises in any sane person at first glance at this dog. The dog is really huge. And this is not subjective - the Hulk is officially recognized as the largest pit bull in the world. He weighs 76 kilograms and is able to almost effortlessly dump the person. Not to mention how threatening the Hulk looks - after all, he is still a representative of the fighting dog breed.Photo: facebook.com/DarkDynastyK9sAll the more puzzling – and even a little awe – is the video of Hulk tenderly caring for three-month-old Jackson, the youngest son of his owners. Marlon and Lisa Grennan are the owners of a dog kennel in the UK. Their job is to breed elite fighting dogs that then “serve” in the police and protect celebrities. The Grennan family’s clients include billionaires from all over the world. Lisa and Marlon trust Hulk as they trust themselves. In addition, the dog has already raised their eldest son Jordan. “When we brought Jackson home, Hulk didn’t leave him,” says 25-year-old Lisa. “He watched me take care of my son, and rushed to him when Jackson started to cry. Hulk is the perfect protector and nanny. He really loves Jackson – you can tell by his eyes. And Hulk’s jaws are so powerful that they can easily bite off an adult’s hand. Besides, he weighs 24 times more than his charge. “Yes, Hulk is a fighter. It’s his job to rush and bite. But that’s only one side of him. After all, Hulk is a protective dog. That is, he must be very balanced,” says 28-year-old Marlon. “I really trust Hulk. He knows that Jackson is a child. And he knows how to be gentle with him, just like with his own puppies.” The father of the family says that the most important thing is to immediately let the dog know who the real alpha male is here. “When you are the leader of the pack, and the dogs recognize it, then there is nothing to worry about. And I have everything under control,” says Marlon.
