Watch This: Meet Miracle Millie, The World's Smallest Dog
Meet Milly, the world's smallest dog, in terms of height. Miracle Milly is from Puerto Rico and measures 3.8 inches (9.65 centimeters) tall at the withers. The diminutive brown Chihuahua is nearly 2 years old and weighs about a pound.
When she was born, Miracle Milly weighed less than an ounce and fit in a teaspoon, says her owner, Vanesa Semler, who gave her milk every two hours with an eyedropper as her mouth was too tiny to nurse from her mother. Millie slept in a doll's crib next to Semler's bed, as she grew stronger as the months passed. The Chihuahua now sleeps in a baby's crib and refuses to eat anything other than human food. Cooked chicken and Salmon are her favorites. She eats four times a day to keep the tiny dog's blood sugar levels even.
Previously, Boo Boo, a long-haired Chihuahua from Kentucky that stands 4 inches tall held the record.
