Beyonce, who weighed just 1 ounce and could fit into a teaspoon when born, could be the world's smallest dog, according to animal rescuers in northern California. The puppy was born at the home of Beth DeCaprio, executive director of the Grace Foundation. The rescuers have submitted an application to Guinness World Records for Beyonce to be considered the world's smallest dog. Picture taken March 10, 2012.[Photo/Agencies]
