Hercules: The World's Biggest Dog Ever According to Guinness World Records Hercules was recently awarded the honorable distinction of Worlds Biggest Dog by Guinness World Records. Hercules is an English Mastiff and who has a 38 inch neck and weighs 282 pounds. With "paws the size of softballs" (reports the Boston Herald), the three-year-old monster is far larger and heavier than his breed's standard 200lb. limit. Hercules owner Mr. Flynn says that Hercules weight is natural and not induced by a bizarre diet: "I fed him normal food and he just "grew"... and grew. and grew. and grew.
Kell: Slightly Smaller, But the World's Heaviest Dog . Hercules' sheer volume may have won him the Largest Dog world record, but the Heaviest Dog title still rests with Kell who weighed in at 286 pounds in August of 1999. This English Mastiff, however, only has a 32-inch neck - far less than
Hercules' 38-incher. Think about that for a second though - 32 inches is a standard waist size for a man!

WOW - Now that's a big dog!

no it is not real. Atleast Snopes says its fake.

How about this photo? Looks real, just hard to believe a fish can get that big!

Just look at the shadows! That is a neapolitan mastiff They do get huge. I wanted one forever. But it;s not real>

Here is part of an article I found with this pic>>>>>

Comments: I urge anyone who thinks this photograph is real -- or even might be real -- to visit a psychiatrist. Right away. Thanks to Photoshop, the dog pictured here (which appears to be a Neapolitan mastiff, not an English mastiff as claimed) is roughly twice its natural size.

Back in 2001, Joe Flynn, the owner of a 282-pound English mastiff named Hercules (see photo), was indeed told by a representative of Guinness World Records that he had the world's largest dog. This is not that animal.

THAT WOULD BE 600 LBS NOT 300.

I would say to the dog no and yes to the Halibut. If that is what it is. Males grow to 80 lbs and females up to 400 if my memory serves me correctly. That dog shadow does look short. Looks late in the afternoon and that shadow should be a lot longer.

WHAT EVER SIZE IT IS, JUST THINK OF THE MESS HE LEAVES IN THE BACKYARD!!!

What sort of beast is that standing to the right of the halibut?

here is a CNN transcript interview with the dog owner.
