Well looking at this picture, I know this dog was a handful. Measuring a whopping 8 feet long and 343 pounds, yes that was 343 pounds. He made the Guinness Book Of World Records and still would have held his title if alive today. Chris Ericlieds of London England was his owner. If there was any large dogs known in the world, it was Zorba which is an English Mastiff. The unusual things was that Zorba was actually a lean dog. I mean this dog was perfect and lived until 13 years of age.
