Hulk, the 12 Stone pitbull belonging to owner Marlon Grennan has become a proud father of eight puppies valued at $500, 000. The pitbull, whose bite could ‘snap a man’s arm like a toothpick’ is pictured showing off his soft side by nuzzling and licking his new brood. There is a probability that the  puppies could grow up to be bigger than their dad. Hulk's puppies would usually sell for up to $30,000 (£19,000) at birth, simply because who their father is. But if they were to be trained as elite protection dogs then Marlon says they could sell for $55,000 (£35,000) or more.

Hulk has been in training to become a protection dog at Dark Dynasty K9s in New Hampshire, USA. He has so far been taught to attack and release on command as well as vault and assault would-be assailants in and on cars. He is said to be a good buddy of Marlon’s three year old son, Jordan. The pair are known to take baths together and sing with Jordan playing the harmonica while Hulk growls.
