|Smallest dog of the world|
The smallest dog living, in terms of height, is a female Chihuahua called Miracle Milly, who measured 9.65 cm (3.8 in) tall on 21 February 2013 and is owned by Vanesa Semler of Dorado, Puerto Rico.
Pocket-sized pets remain one of the most fascinating areas of the Guinness World Records database, with petite dogs arguably the most popular of all our animal records.
Guinness World Records currently has two main categories for petite pooches: Smallest dog living (height) and Smallest dog living (length).
Born in December 2011, she weighs roughly 1 pound (half a kilogram) and is known for often sticking out her tiny tongue when someone takes her picture. "She knows how to pose," says Vanesa.
"People are amazed when they see her because she is so small, and she has a big personality. People love her."
When she was born, Miracle Milly weighed less than an ounce and fit in a teaspoon, Semler said. Her mouth was too tiny to nurse from her mother, so Semler gave her milk every two hours through an eyedropper.
She slept in a doll's crib next to Semler's bed, growing stronger as the months passed.
The Chihuahua now sleeps in a baby's crib and will eat nothing but food cooked by humans.
