A play on bloco (street party) and cao (dog), Blocao even features a few courageous cats that also want to let their hair down. “The neighborhood of Copacabana has currently the most dog owners per square meter,” says Blocao organizer Marco Antonio Toto. “It deserves this prestigious party. Our animals deserve this celebration.” Christophe Simon, AFP / Getty ImagesWONDER DOGSuperhero costumes are always popular at Blocao—and this dog captures the essence of Wonder Woman, right down to the bracelets and golden lasso.

Must be the Carnival spirit.” Charlie Varley / SipaMYSTIC KREWE OF BARKUSRio isn’t the only city that lets its annual Mardi Gras celebration go to the dogs. In New Orleans this year, the Mystic Krewe of Barkus returned to Armstrong Park in the French Quarter for its annual parade, featuring lots of costumed pets and children. Founded in 1993, Barkus—whose name is a play on the Krewe of Bacchus—raises awareness and money for animal shelters in the Gulf region.

This year’s winners—King Wally, a poodle-and-retriever mix, and Queen Maggie, a golden Lab—were treated to a celebration at the legendary New Orleans restaurant Galatoire’s.

Though dressy flashy helps.
