Marching from Madison Square Park down to Union Square comes the cutest, sloppiest, most glorious doggy parade ever, all in celebration of the ASPCA's 150th anniversary. Witness the march of NYC's loveliest dogs and the people who devote their lives to their protection at this first annual parade led by internet-famous critter Marnie the Dog. What’s better than watching dogs tromp through Manhattan? Adopting one of those four-legged cuties! After the parade, head to a fee-waived adoption party in Union Square.
