This heartless Long Island breeder allegedly kept 21 Rottweilers, including puppies, in freezing weather outside his home — and lied to The Post about the dogs’ whereabouts and his own identity.

Jose Borgos, 52, popped out of his house in Rocky Point briefly on Friday, a day after his arrest on animal cruelty charges.

He immediately claimed he wasn’t Jose Borgos.

“He’s not home,” he lied.

Borgos’ ramshackle ranch house is apparently toasty enough that he was comfortable in the same orange T-shirt he wore in his mugshot the day before.

But Borgos had kept his dogs outside on Thanksgiving morning in the bitter cold of his back yard — caged in a tarp-covered, chain-link-fenced kennel and in travel crates inside an unheated shed, according to Suffolk County police officials.

The Rottweilers were of “mixed” ages, a law-enforcement source said when asked if they were all adult dogs or included puppies.

“They’re in the basement,” Borgos lied Friday of his dogs, which officials said actually remain in the custody of local Animal Care and Control workers.

The breeder was busted at around 10 a.m. Thursday, after a passing patrol cop heard barking and pulled over, Suffolk County police said. It was just over 20 degrees out at the time.

Borgos remains free without bail, charged with misdemeanor violations of state and local regulations banning the keeping of dogs outside in sub-freezing weather.

But he had a couple other guests after The Post came knocking on Friday: two Suffolk County police officers who came by for a follow-up visit.

“He lied to you,” one of the cops deadpanned to The Post of Borgos’ “he’s not home” claim.

Long Island has been an inclement place for Rottweilers of late.

In July, three Rottweilers were found dead after spending more than 11 hours inside a sweltering Ford Explorer parked in the lot of the Majestic Corners Shopping Center along Montauk Highway in Shirley.

Temperatures had climbed to a high of 90 degrees that day.

The three surviving Rottweilers in the car, including a puppy and two juveniles, were taken to the Brookhaven Town Animal Shelter — the same shelter with custody of the Borgos dogs.

The car, and the poor pups, were owned by Carmine Dapruzzo, 41, of Shirley, who likewise remains free on bail and charged with misdemeanor animal cruelty.

“It was a mistake,” he conceded to News12 Long Island after his arrest.
