Bitches, please!

A Stockholm resident wants to build a new dog park with one rule: no (dog) boys allowed.

In the Swedish capital, it’s socially verboten for female dogs in heat to frolic in dog parks, according to local news outlet StockholmDirekt.

The pooches aren’t partitioned without cause: It’s a widely held opinion that female dogs in heat shouldn’t be in close quarters with unneutered male dogs, who may get riled up from the interaction.

But artist Carola Kastman, owner of 5-month-old border collie-Doberman-Rottweiler mix, Coco, thinks it’s downright discriminatory that pups like hers are barred from Stockholm’s dog runs for the roughly three months per year they are menstruating.

“I could never have believed that patriarchy had entered the dog parks,” she tells StockholmDirekt.“This is a major political issue. I will not be happy until there’s at least one sex-separated dog run for female dogs in every neighborhood.”

Her “citizen’s proposal” to open a female-only dog park near her neighborhood of Sodermalm will be considered by the local government — although the chairman of Sodermalm’s district council declined to comment to StockholmDirekt “because he is not a dog owner himself.”

Reaction to Kastman’s campaign, first publicized Wednesday, has been positively rabid.

A rep from the Swedish Kennel Club told the paper that building female-only dog runs was unnecessary. He also denied accusations of discrimination: “It’s about animals, not humans.”

Emelie Draper — a local breeder, doggie-daycare worker and rock DJ — opined to the paper that Kastman’s idea is good in theory, but not practice. “I’m afraid there would be total chaos,” she writes, explaining that female dogs in heat may fight aggressively with each other.

‘It is very interesting and scary that the gender roles in society are reflected in the cultural animal world. It is time for a change.’

On Wednesday, Kastman wrote on her personal blog that she feels like she’s the target of a “witch hunt.”

The following day, she penned an opinion piece on another site, News24, defending her position.

“Right now, there are many frustrated dogs on the streets of the city who just want to play with their friends,” Kastman writes. “In greater Stockholm, there were a total of about 110,467 dogs in 2015. Half of these may be without play two months a year. It’s a big question why it’s the females who [are banned] and not the male dogs, when they are the [trouble-making] ones.”

She also offered to personally take care of the operation of a female-only dog run.

In an e-mail to The Post, Kastman observed that this canine conundrum runs contrary to Sweden’s typically progressive policies.

The country, she says, “is at the forefront of gender-neutral policy and animal rights. It’s incredible that there are not any such places, and Sweden should be a role model.”

Kastman points to a video she posted on Instagram of Coco getting harassed at the dog run earlier this month.

Kastman is ready to fight for a dog run where Coco — who has her own Instagram account — and other female dogs can find “peace and quiet,” she adds. “Even when they do not have their period, the males are on them all the time.”

“I will continue to question this ‘invisible rule,’ where the males have the power,” she wrote for News24. “It is very interesting and scary that the gender roles in society are reflected in the cultural animal world. It is time for a change.”
