At 1 pound, 5 ounces and 4 inches tall, Boo Boo, a Chihuahua from Raceland, Kentucky, holds the Guinness World Record for being the world's tiniest dog. Lana, Boo Boo's owner, says she was the size of her thumb at birth and weighed less than an ounce. "I fed her with an eye dropper because she couldn't even take a bottle," Lana says.
Now, Boo Boo eats 2 tablespoons a day. "Her biggest meal is breakfast. She has a tablespoon of food," Lana says. "I fix her ground turkey with peas and carrots in it."
