She’s Got ‘The Biggest Pit Bull In America,’ Now Mom Lets Him Meet The Newborn Baby


Marlon and Lisa Grennan are the proud owners of Hulk, the world’s largest, most powerful and biggest pit bull.


This beautiful, giant, biggest pit bull in America weighs upwards of 180 pounds; and can “snap your arm like a toothpick.”

But recently, Hulk met the newest member of the pack, Marlon, and Lisa’s tiny newborn son, Jackson. He’s 22 times Jackson’s size!


In the video below, Marlon and Lisa bring their son home from the hospital and prepare to introduce him to Hulk. As you’re about to see, Marlon is not worried in the least about how Hulk will react to Jackson’s arrival. “I’m the Alpha of the house,” he says. “I know everything will go smoothly and they’ll love him just as I’ll love him.”

Their eldest son, Jordan, grew up with Hulk and other American pit bull terriers on their property in New Hampshire. For the past five years, Hulk has babysat Jordan and watched over him like a protective big bro.

Marlon’s company, Dark Dynasty K9s, specialize in training elite protection dogs for the police, celebrities, and billionaire clients around the world. They hit fame in 2015 when videos featuring Hulk and their other dogs went viral, racking up more than 100 million views on YouTube.

Yes, Hulk is trained to protect and defend, but he knows when it’s time to settle down and be gentle.

These dogs make for loving, protective family members, and it seems both of Hulk’s brothers are going to be more than taken care of.
