I had one of these gental giants about 15 years ago, he weighed 87 kgs and stood 76cm's at the shoulder Here is a shot of 'tiny' in his **read--MY bed BUT ............. Hercules was recently awarded the honourable distinction of Worlds Biggest Dog by Guinness World Records. Hercules is an English Mastiff And 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.
