CANINE INTERNET sensation the Hulk made light work of a masked and armed intruder who climbed into the family’s New Hampshire home. The colossal 180lb pit bull went on the attack and apprehended the invader after being ordered into action by owner Lisa Grennan, of protection dog breeders Dark Dynasty K9s. Luckily for Lisa, 28, and husband Marlon Grennan, 31, the burglary was part of a simulated home invasion scenario, with trainer Jeff Cummings the man behind the mask. The high-impact stunt features in the new season of Barcroft TV’s hit online show Dog Dynasty, which has racked up more than 150 million views on YouTube and Facebook. The show follows the fortunes of Hulk and the other DDK9 protection dogs, which sell for between $5000 and $25,000.
