A giant canine in Michigan is the tallest dog on the planet. The Great Dane towers 7 feet 4 inches.

According the Guinness Book of World  Records released on Thursday, the canine weights almost 150 pounds and eats 30 pounds of food every day. The book says, it is the tallest dog ever been recorded.
The French news agency AFP reported that 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.
