Golden retrievers Gus and Jake have attracted quite a bit of attention with their Halloween costumes for the past few years.

One year, one was dressed up like Pennywise from the “It” novel and film while the other wore a yellow raincoat to symbolize the child character George from the story.

This year, the dogs were dressed as Joker and Harley Quinn from the movie “Suicide Squad” and they won for best overall costume at the Frankfort Park District’s “Howl-a-Wolf” event Saturday at its dog park.

Their owners, Ken and Julie Lehocky, of New Lenox, said the dogs were getting so much attention that they became too excited to search for treats in the park’s “boneyard.”

About 50 dogs and their owners showed up for the event, now in its eighth year, which included a costume contest and a hunt for treats in the field like an Easter egg hunt.

The treats included dog biscuits or redemption coupons for free gift baskets from local dog service businesses.

Owners also received an information packet about signing up for a membership at the dog park.

“I’d definitely consider joining,” said Katie Nikelc, of Frankfort.

Her chocolate lab, Wally, was sandwiched between pillows of a marshmallow and two graham crackers to make a s’more.

Nikelc said this was the first time she brought her dog to the park as she’s become comfortable with it after Wally attended obedience school.

Park officials require that unruly dogs must be removed from the dog park.

They encourage dogs to be unleashed because leashed dogs feel threatened by dogs that are not.

In the rare instance a fight among dogs occurs, park officials say owners should grab their dogs by the hind legs and pull.

An annual membership to the park costs $60 per family for Frankfort residents, which includes a $10 key card that doesn’t have to be purchased again in following years.

The park fee is $5 more for non-residents.

Dog costume winners from Howl-a-Wolf also were awarded a free one-year membership to the park.

Yvette Betancourt’s 16-year-old Chihuahua, Aldo, was dressed as a sumo wrestler and won for funniest costume.

The Chicago resident said she’s been bringing Aldo to the event for five years, but this is the first time they’ve won the costume contest.

Brittany Jurek, of Lansing, said this was her first time coming to the event. Her German shepherd mix, Rogue, who was dressed as a spider, won for scariest costume.

Although not a costume contest winner, Lisa and Gail Williams’ Cavachon dog, Joshua, was probably one of the better dressed with his 1920s era tuxedo and top hat.

“He’s dapper Dan the ladies’ man,” Gail Williams said. “It’s just fun. He so enjoys getting out and doing it. He gets excited when you put his clothes on.”

Last year, Joshua was dressed as a skunk.

The final Frankfort Park District Halloween-related event this year is its scarecrow building contest.

The scarecrows are on display outside the Founders Community Center and voting can take place there or on the district’s Facebook page.

The scarecrow “Lemontine” as of Wednesday was leading in “likes” on the Facebook page with 349 followed by “Coco,” inspired by the movie, with 290 votes.

Voting takes place until Oct. 31.
