HAT'S ALL

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.
