Meet Boo-Boo, a tiny chihuahua who just made the giant leap into history by being the new World's Smallest Dog:
At just four inches tall, "Boo-Boo," a diminutive dog in Raceland, Ky., just edged out another chihuahua to win the crown.
Lana Elswick says Boo-Boo was born the size of her thumb. Elswick says from the beginning she knew her dog was special, but it wasn't until a few weeks ago that she knew just how special.
"There was this contest going on between two little dogs, but I knew I had the smallest one. But, I just had to wait until I had my certificate to show everyone," Elswick says.
The Guinness Book now considers the full-grown though petite pet the smallest dog in the world, nearly an inch smaller than the previous record holder.
