Take a bow-wow Milly the chihuahua: Micro mutt that fits in the palm of a hand and weighs less than a banana is set to be crowned the World's smallest dog

She may be tiny, but Milly the Puerto Rican chihuahua is on the verge of something big - being officially recognised as the most petite pooch on the planet.


The current record holder is Boo Boo, another chihuahua from the U.S state of Kentucky, but Milly, who lives with her Argentine owners in the north east Puerto Rican town of Vega Alta, hopes to punch above her 170g weight to earn her place in the Guinness Book of Records.

After she was born three months ago the family believed that Milly would grow, but having maintained the same height of just 6.53cm for three weeks they began to think that the pedigree pup might be able to knock Boo Boo from the top dog spot that she has held since February 2008.       More
