For me this dog is more like a rat!
Anyhow Milly the chihuahua is the world's smallest dog with weight just 170gms and height of only 6.53cm.
The tiny creature is fromVega Alta, Puerto Rica and has Argentinian owners who are going to present the dog to the Guinness Book of Records because they believe she is the smallest in the world.
Meanwhile Boo Boo carries the current title for the smallest dog in the world which measures 10.16cm tall and is owned by Lana Elswick of Raceland, Kentucky.It is a long-haired, female chihuahua which held the title since February 2008.
Milly is three months old and has maintained the same height since she was just three weeks old.It was expected that she would grow more but it did not come about as thought.
Mill's owner told about her:
'Milly was so small she could not breastfeed due to the tiny size of her mouth.
'To get an idea of just how petite she is, when she was first born she received milk from an eyedropper.'
The owner does not have their own children so they spend all their time and energy in providing the special care to this dog and are whole heartedly dedicated to rearing chihuahuas.
