At least five dogs have been zapped by stray voltage on a Brooklyn sidewalk — and protective pooch owners are barking mad over the shocking hazard, sources told The Post.

The pups were jolted at an “abandoned” electrical site in Bedford-Stuyvesant, where salt and melted snow acted as a conduit between metal manholes, according to neighbors and Con Edison.

“Be aware that this can happen! ” one dog owner warned on Reddit after his adopted pooch received the paw-stinging jolt.

At first, the man couldn’t figure out why his pup was acting nervous near Throop Avenue and Kosciuszko Street, he wrote under the handle Allen_MacGyverson.

“The last few times we’ve neared the end of the walk approaching my building, she’s dug her paws in and refused to move,” he said in the post. “I chalked this up to her not wanting to go inside… I’ve also assumed it’s salt in her paws.”

But, when his pooch “buckled” in pain on Tuesday, he started talking to neighbors — and learned that at least four other dogs have been zapped at the same spot, he wrote.

Workers hustled to the block, set up cones and “deactivated” the electricity Tuesday, said ConEd Spokeswoman Joy Faber.

“We identified and deactivated an abandoned electric service. Our apology for the disruption,” she said.

Cases of mutts shocked by stray voltage — including ones in which dogs have died and been seriously injured — spike in the winter, when large amounts of snow begin to melt, according to Faber.

“Around this time of year, after a major snowfall, we hear about this happening. The salt and water serves as a conduit for electricity on metal surfaces,” Faber said.

The zap generally doesn’t hurt people — as long as they’re wearing shoes —but it can do a number on Fido’s feet.

“It can be painful to pets, especially small ones,” Faber said, adding, “[ConEd] conducts stray voltage patrols regularly.”

Last February, three canines were zapped in the West Village. In February 2014, a 50-pound pit bull named Bella died from stray voltage on the Lower East Side, neighbors said.

In Bedford-Stuyvesant, neighbors near the stray voltage site feared things could still get hairy — since no warning signs had been posted Tuesday.

“ It’s really scary especially since my dog is so small,” said Tori Berle, 26-year-old copy writer, who was walking her Chihuahua, Fox, near the site.

“I feel like if this is an issue, I should have been notified,” she said. “This should be a city- wide thing that people are aware of.”

She added, “It’s important whether you live in Brooklyn or Manhattan, or whatever borough — because there are manholes everywhere.”

Dylan Long, a photographer with a husky-German shepherd mix named Willow, said electrical companies should immediately install warning signs when they hear about stray volts.

“Our dog has a heart murmur and if she got shocked by something, she could potentially have a heart attack,” said Long, 29. “Con Ed should post a sign and say, ‘Heads up!'”
