London, Nov 9 : Despite their drastic difference in size, two dogs, Gibson the Great Dane and Boo Boo the toy Chihuahua have something in common - both are world record holders.

Measuring a massive 42 inches, Gibson was named the tallest dog on the planet back in 2004.

Joining him in the hall of fame for 2007 is tiny Boo Boo, the world's tiniest dog, who only measures 10.16cm tall and is smaller than Gibson’s head.

The two celebrity hounds, who were both bred in America, met on Guinness World Records Day in Gibson's home town of Sacramento, California.

Boo Boo’s owner, Lana Elswick from Kentucky, insisted that the pooch was nothing like his size when it came to guarding her.

"She tries to guard me,” the Mirror quoted Lana, as saying. (ANI)
