You might think that Hulk is just a nickname for a big dog – but Hulk is actually the biggest pit bull you can find on the planet. Weighing an impressive 175 pounds (which is about the weight of a slightly slimmer 20-year-old), he’s absolutely gigantic and able to rip a man’s arm off in a blink of an eye.

This might seem terrifying, but Hulk is actually a ‘gentle giant’. His owners Marlon and Lisa Grennan have been training him all his life and feel completely safe letting him around their three-year old son Jordan.

Well, Hulk’s a daddy now, with eight adorable pups to grace his legacy. Not only are they the cutest pupps ever, but they are also worth around half a million dollars, and are all already sold! All that is left now is to see whether one of them will outsize him – an impressive feat, which would require an impressive doghouse.
