The World's Smallest Dog

Above is Boo Boo. She is the world's smallest dog. She is four inches (10.16 centimetres) tall. That's about the size of a mobile phone! When Boo Boo was a puppy, she was the size of a thumb.

Boo Boo is a chihuahua, which is the smallest breed of dog, so it's no surprise that Boo Boo is that tiny. Her owner is called Mrs. Elswick and she didn't find out about this until the tenth of September. Boo Boo was actually measured in May.
