SAN JUAN, Puerto Rico – Guinness World Records has announced that the world's smallest dog — at least when it comes to height — lives in Puerto Rico.
The brown Chihuahua named Miracle Milly is shorter than a soup can, standing at 3.8 inches (9.65 centimeters) tall when measured from backbone to paw.
She is nearly 2 years old and known for repeatedly sticking out her tiny tongue.
Milly dethroned Boo Boo, a long-haired Chihuahua from Kentucky that stands 4 inches (10.16 centimeters) tall.
Guinness also has a second category for world's smallest dog when measured by length. That title is held by Heaven Sent Brandy, a Chihuahua in Largo, Florida, that measures 6 inches (15.24 centimeters) long.
Guinness officials made the announcement Thursday.
