What a paw-ty!

Dozens of dogs in costumes celebrated Howl-o-ween a little early Sunday at the annual Luna Park dog parade in Coney Island.

Dressed up as everything from cops to prison inmates — with some ghostbusters, aliens, witches and even a UPS delivery driver and hot dog vendor — the costumed canines strutted in the park to “ap-paws.”

Siberian Husky Max came as Super Mario video game character Yoshi, a green dinosaur, earning him the day’s people choice award.

Owners Shabelle Valencia, 29, and Arguimedes Valencia, 24, took home a bag filled with dog food, toys, Luna Park vouchers and a doggy bed as the prize.

“I never thought we were going to win. It’s awesome,” said Arguimedes.

Other owners went a more DIY route. Karen Wang, 49, used soda bottles, goggles and fins to fashion a scuba diver outfit for her dog Muffin.

“She loves the water so it was fitting,” said Wang, who lives near Coney Island.

Laura Molina, 28, turned a cardboard box into a hot dog vendor costume for her pet Pomeranian, Roo.

“Every year I create a box costume for him out of an Amazon box … Last year he was a tissue box,” she said.

Some owners, like Maud Keisman, used the puppy party as a teaching opportunity.

The 57-year-old put her rescue pup Steetwa in a black and white prison jumpsuit with a “bad pet” sign over her neck that read: “Charges: Squirrelcide in the 1st degree.”

“She always looks guilty,” Keisman said.
