The giant canine from Michigan in the United States eats an entire 14-kilogram (30-pound) bag of food every day and weighs in at 70.3 kilograms, the 57th edition of the global records book says.
Measuring 1.12 metres (44 inches) from paw to withers -- the point between the shoulder blades at which the official height of a four-legged mammal is judged -- he is officially the tallest dog ever recorded, the volume claims.
'Guinness World Records 2013' says the humongous hound breaks the record of Giant George, another Great Dane who is one inch shorter.
"The most common thing people ask is: 'Is that a dog or a horse?'" says the three-year-old's owner Denise.
"We had to get a van to be able to transport him, oh, and if he steps on your foot he leaves bruises!"
The book -- the latest edition of the world's best-selling copyrighted series -- also names Oklahoma Sam, a four-year-old American Mammoth Jackstock, as the tallest living donkey on the planet.
Measuring 1.55 metres (5 feet 1 inch) from hoof to withers, she dwarfs the average common donkey (80 centimetres, 2 feet 8 inches) and the average for her own larger breed (1.22 metres, 4 feet).
The four-year-old record-breaker lives in Watsonville, California, where she shares her one acre of land with a macaw, duck, goose and four cats.
The new book, which claims to reveal "the latest and greatest records in the universe", recognises the world's shortest woman as 18-year-old Joyti Amge from the central Indian city of Nagpur.
The book bestows the title of the world's oldest gymnast to 86-year-old Johanna Quaas, born on November 20, 1925 and a regular competitor in the amateur Landes-Seniorenspiele competition in Saxony, Germany.
