This is Hercules, The World's Biggest Dog Ever according to Guinness World Records. Oh, in case you are wondering, he is the one on the far right in this picture. Hercules is an English Mastiff and he has a 38 inch neck and weighs 282 pounds. That is one Big Doggy! I can just imagine how much food he gets. Probably a whole lot more than I do. Lucky guy. But anyway, yeah he's big and all, but remember, you shouldn't judge a dog by how big he is, you should judge him by the length of his tongue.
