The champions of the 22nd annual Tompkins Square Park Halloween Dog Parade were no strangers to the winner’s circle. The pup that ranked Best in Show has won a similar contest on the Upper East Side the last three years, dressed as a hurricane and as Beyonce. Gracie, winner of the second round, took Best in Show two years ago as Scarlett O’Hara. That year, Benny the boxer also got a prize as Internet sensation Antoine Dodson.

This year it was Benny’s behind that got all the attention: glasses and a wig were perched atop his tiny tail to make it look like a wiggling nose.

The Butthead costume was spontaneous. “I wasn’t sure I was going to dress him up,” said Benny’s owner, Michael Godere. But the dog’s godfather, Grover Guinta, came over that morning with a bag of wigs and glasses. “We just improvised,” Mr. Godere said, laughing when another dog sniffed Benny’s rear-end. “It’s great when the other dogs try to kiss his butt.”

The other two winning costumes took more preparation. “We’ve never done so much papier-mâché in our lives, but it was worth it,” said Best-in-Show winner Bennett Leak of the enormous moon costume Brett England wore. Their dog, Mattie, was wrapped up in Mr. Leak’s bike basket a la E.T., with Mr. England standing behind them inside a giant moon with twinkling battery-powered lights.

Dewey Moss gave his dog Gracie the royal treatment. He had built a balcony-like platform, complete with microphones for addressing a crowd, for Gracie, who wore a gold Eva Peron dress. Mr. Moss carried a small boom box playing the “Evita” soundtrack.

“She always looks kind of drunk and she sleeps a lot, so it’s easy to put her into a costume,” Mr. Moss said of Gracie, whose tongue was hanging out of her mouth, her eyes partly closed.

Though none of the first-place winners this year were political, a costume called Seamus’s Revenge took a close second in Gracie’s round. The dog, Laika, was inside a cardboard station wagon, with a Mitt Romney figure strapped to the top, as he is known to have once done to his family dog, Seamus.

Also sniffing around were a fire truck, a turkey, a sight-seeing bus, astronauts, Pac-Man, Rapunzel, the dog from Pixar’s “Up,” and two chihuahuas in matching Our Lady of Guadalupe dresses who later changed into sparkling tuxedos.
