A puppy that weighs 163 grams at five weeks old may be the world’s smallest.

Kim Passero didn’t think her Yorkie would make it. She calls her a little miracle, which is why she named her Angel.

“She’s incredible, she has a personality and she is loving, she’s like a typical dog, she’s just really tiny.”

Five-week-old Angel is about a quarter of the size of her litter mates.

When Angel was born, the odds were stacked against her. She was so small her brothers and sisters pushed her out of the way during feeding. Even when she was able to latch on to her mom, she couldn’t get enough milk. So Passero has been feeding her formula ever two hours from an eye dropper.

“She didn’t have the strength to suction the milk out of her mommy so I started giving her the dropper and this way she actually starting to put on weight.”

Right now the smallest dog in world is held by a Chihuahua named Milly. And rather than looking at weight, the Guinness World Record measures a dog’s height and length to make sure no one underfeeds their pets.

In order to qualify, a dog has to be one-year-old so Angel has time to focus on getting healthy before turning one next August.
