The World's Smallest Dog: All Grown Up!A year after her birth, PEOPLE looks at how Tiny Beyonce is catching up to the objects that used to tower over her


In March 2012, rescue dog Tiny Beyonce entered the world weighing just 1 oz. and measuring less than 4 in. long, quickly earning the title of world's smallest dog. Even at 2 weeks old, when the photo at left was snapped, she weighed just one-quarter of a pound. A year later, she's up to nearly 3 lbs. and is doing just fine, despite her rocky beginnings.
