World’s smallest dog lives in Puerto Rico. Guinness World Records announced Thursday that the brown Chihuahua named Miracle Milly — 3.8 inches tall when measured from backbone to paw— is the world’s tiniest dog at least when it comes to height.
She is nearly 2 years old, weighs roughly one pound and is known for often sticking out her tiny tongue when someone takes her picture.
"She knows how to pose," owner Vanesa Semler, who lives in Dorado, Puerto Rico, told The Associated Press.
Miracle Milly unseated Boo Boo, a long-haired Chihuahua from Kentucky that stands 4 inches 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 long.
Milly sleeps in a baby's crib and apparently is a very picky eater.
"She really likes salmon and chicken," Semler said, noting that she eats four times a day.
Miracle Milly is one of 10 Chihuahuas that Semler owns, and is easily the most popular.
"People are amazed when they see her because she is so small," Semler said. "And she has a big personality. People love her."
