The owners of the world’s largest pit bull are so gullible that they allow the twelve-stone dog to babysit their newborn son. Marlon and Lisa Grennan even let the world famous Hulk lick and babysit their tiny boy Jackson.
But this isn’t the first time the couple has done this, as their eldest son Jordan grew up with the Hulk and other American Pit Bull Terriers at their New Hampshire, US property.
Marlon’s company Dark Dynasty K9s specializes in training elite guard dogs for police, celebrities and billionaire clients around the world. They rose to prominence in 2015 when videos featuring the Hulk and their other dogs went viral, racking up over 100 million views on YouTube alone.
