A Long Island family was reunited with its adorable 11-year-old Shih Tzu on Christmas night — a week after the pooch was stolen, officials said.

Detectives with the Suffolk County SCPA, who had been working the case since Bella disappeared last Wednesday, promised Fortuna Feliciano, 39, and her family they would find the dog by Christmas.

“When they drove up to the driveway with Bella … my heart just healed. It’s an emotion that’s very hard to explain,” Feliciano told The Post about the happy ending that occurred two minutes shy of midnight.

“What a Christmas gift, incredible.”

Feliciano’s nightmare began once she noticed Bella, the family’s only dog, managed to escape from the yard of their Ronkonkoma home.

“I realized Bella was gone, so I’m looking everywhere,” explained Feliciano. She took her son two sons off the school bus and into her car to scour the neighborhood.

“I threw them in the car we drove up and down the road looking for her — and I came back home in a panic,” said Feliciano.

During her search, Feliciano missed a call on her cell phone from an Amazon delivery worker who found Bella.

But, by the time she returned the call, the worker gave the dog to a woman jogging in the area who told him, “’I know who’s dog that is.'”

“The family was very upset,” Roy Gross, chief of department of the Suffolk County SPCA said once they learned Bella was taken by a stranger.

In the seven days Bella was gone, Feliciano said her family, neighbors and detectives from Suffolk County SCPA worked tirelessly to locate their dog.

“I felt that I had lost my child,” said Feliciano. “I never stopped looking for her.”

On Monday, the Suffolk County SCPA announced a $2,000 reward for information leading to the arrest and conviction of whoever took Bella.

Then on Christmas Day, the organization caught a break.

“We got a tip, and we got the dog back,” explained Gross.

Gross said an investigator from his department reached out to the family about 10 p.m. Christmas night to break the news.

The investigator “calls her up and says ‘I’m driving to your house with the dog,’” Gross said.

“He gets the dog to her at two minutes to midnight,” he said. “It was a real miracle that they got the dog back.”

It’s unclear who the Suffolk County SPCA retrieved the dog from. The investigation into the dog theft in ongoing.

“It’s not over yet because we need to find out who was responsible for stealing the dog,” said Gross.
