Even dogs can celebrate Halloween - and here's a show to prove it.Canines of all breeds sent tongues and tails wagging as they took part in the 2011 Tompkins Square Park Halloween Dog Parade in New York on Saturday.The field of around 500 very patient pooches was packed with inventive and hilarious costumes, including a stegosaurus, Don Draper from Mad Men and a bride.The parade of masquerading dogs is the largest Halloween Dog Parade in the U.S.A pup done up like Lady Gaga from the 2009 VMAs won a prize for being best dressed.But the top dog gong of Best in Show went to a canine disguised as an M23 New York bus, fully equipped with its very own passenger, the owner's child.The proceeds raised during the event go to the oldest dog run in New York City.
