SAN JUAN, Puer­to Rico — Puer­to Rico can now boast it is home to the world’s small­est dog — at least when it comes to height.

The brown Chi­huahua named Mir­a­cle Mil­ly is short­er than a soup can, stand­ing at 3.8 inch­es (9.65 cen­time­tres) tall when mea­sured from back­bone to paw, Guin­ness World Records announced Thursday.

She is near­ly 2 years old, 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,” own­er Vane­sa Sem­ler told The Asso­ci­at­ed Press.

Mir­a­cle Mil­ly dethroned Boo Boo, a long-haired Chi­huahua from Ken­tucky that stands 4 inch­es (10.16 cen­time­tres) 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 cen­time­tres) long.

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.

“She real­ly likes salmon and chick­en,” Sem­ler said, not­ing that she eats four times a day.

Mir­a­cle Mil­ly is close to her two sis­ters, both which are of nor­mal size, but she prefers the com­pa­ny of people.

“She does not under­stand that she is a dog,” Sem­ler said. “She thinks she’s a kid.”

She does­n’t bark and likes play­ing with the plants in Sem­ler’s back­yard. If there are birds to chase, even better.

If she’s play­ing inside, she grav­i­tates toward Paco, a yel­low Chi­huahua plush toy twice her size. The stuffed ani­mal is among dozens lin­ing her crib.

“We give her a new toy almost every week,” Sem­ler said. “She likes to cud­dle with them.”

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.”
