A jilted Long Island contractor wants his dog back from his ex — plus $11 million to cover the anguish of living without his four-legged friend since a bitter split in February.

But the former girlfriend of Illich Jorquera, 36, says he’s a violent, jealous “stalker” and she’s not about to turn over Guapo, a 2-year-old schnauzer.

“He’s a psycho,” said Carla Pimentel, a 29-year-old Manhattan Spanish teacher. “He’s stalking me. I took my dog and left when he wasn’t around because . . . he would have tried to stop me.”

Jorquera, of Carle Place, filed the whopping lawsuit yesterday in Queens Supreme Court.

“I was in love with him,” whined Jorquera, recalling the day he and Pimental bought Guapo as a puppy. “When he looked at me, it felt like he would be with me forever.”
