Pooches let their alter-egos shine, putting on some of the cutest and most creative costumes you've ever seen at the annual Tompkins Square Halloween Dog Parade. CNN calls it "the largest dog costume parade in the world” with hundreds of dogs in costumes and thousands of spectators. The London Guardian says “It’s Barkin’ Mad.” This year's parade will be sponsored by Purina Beggin' with contestants competing for thousands of dollars in prizes.
