This one really is for the record books – how small do you think a dog can get?
The world’s smallest dog, according to the Guinness Book of World Records, is Miracle Milly. She’s a Chihuahua who lives in Puerto Rico.
She is only 3.8 inches tall (see photo above for scale).
Since she is a Public Figure, Milly has her own Facebook page and, like many small dogs, her owner likes to dress her up for photos.
