An Upper West Side husky is attacking other animals in Central Park — and has killed a Chihuahua and allegedly left a Dachshund in critical condition.

“You go to the park for a walk and you come home with a box,” said Deidre Bailey, the owner of Chihuahua Belle, who was allegedly shaken to death by the bigger dog in August 2018. “It’s been an emotional nightmare.”

Local dog owners claim that, despite their efforts to reason with the killer dog’s owner, Matthew Stock, the Siberian husky is still roaming the park off-leash and unmuzzled. (Stock disputes this, saying his dog is leashed.)

“We need to get this dog off the streets,” said Elizabeth Graham.

Her miniature dachshund, Lulu, was left needing medical treatment — including a spleen removal that cost nearly $25,000 — after the 2-year-old husky, Charlie, allegedly sank his teeth into the small dog on Aug. 12.

“If in one second he was able to do this to Lulu, can you imagine what he could do to a child?” asked Graham, 58.

She was on vacation in France when her friend, Victor Mejia, took 11-year-old Lulu for a walk near the west side of the 97th Street transverse around 8 p.m.

Suddenly, Meija claimed, Charlie darted over.

“Lulu made a little bark, and the husky went straight at her and attacked,” Mejia said. “I pushed the [husky] in the stomach to get rid of it, and grabbed her.”

Mejia, 34, wrapped his T-shirt around Lulu’s bleeding stomach, while Charlie’s dog walker, Ann Marie Fierro, “just stood there frozen” and “didn’t offer any help,” he recalled.

At Blue Pearl animal hospital, doctors had to remove Lulu’s heavily punctured spleen.

When Graham arrived in the US a few days later, “[Lulu] had a tube in her neck for oxygen, the flesh was twisted, she was very black and blue and she had staples in her stomach,” Graham said. “It’s a miracle she’s still alive.”

Stock agreed “to pay all bills” for Lulu, he stated in an e-mail to BluePearl Veterinary Partners, but has so far only remitted $2,925.

“I don’t have that kind of money,” he told The Post. “What I paid was a good effort.”

Graham hung more than a dozen posters near Stock’s West 93rd Street home, and at the West 93rd Street entrance to Central Park, warning about Charlie.

“We’ve got to protect the community,” she said.

Stock said it’s “a smear campaign” and that he is treated as the “villain of the Upper West Side.”

“It’s harassment,” he said. “I feel terrible about what happened … this is just too far. [Charlie’s] not a command killer dog.”

Stock and Fierro the walker told The Post Mejia and Graham have it wrong, claiming that it was Lulu who approached Charlie — and that the husky was on a leash because of the other times he has killed animals, including “several raccoons.”

“What happened last year was a tragedy, and ever since then we’ve been very careful to keep him on leash,” said Stock, referencing the 2018 death of Belle the Chihuahua.

Four-year-old Belle and her owner, Bailey, were playing fetch when Charlie, in the park with Stock’s stepson, came over.

“It cornered my dog and shook her like a rag doll three or four times,” said Bailey, 47.

She rushed Belle to the ER, but the dog died shortly after arriving.

“I cried and cried for days and weeks,” Bailey said. “I would pay any amount — millions — to get that dog back.”

Although Bailey didn’t take any action against Stock, local canine owner Susy Nastasi — who witnessed the attack on Aug. 26, 2018, — hung warning flyers and filed a complaint with the city.

“I started telling everyone to watch out for Charlie,” she said.

On Thursday, the Department of Health and Mental Hygiene sent Stock a stipulation, seen by The Post, outlining both incidents and stating that Charlie’s “history of aggressive behavior … poses a risk to public safety.”

Stock told The Post that he will “fully cooperate” with the order that Charlie complete a training program and wear a muzzle and leash in public at all times.

If he does not cooperate, Stock will have to surrender Charlie.

Meanwhile, Bailey — who buried Belle in Colusa, Calif., where the dog was adopted — couldn’t bear to stay in New York any long­er. In June she moved from Chelsea to Los Angeles.

“I was like, ‘I ‘gotta get out of here,’ ” she said. “It just wasn’t the same without [Belle].”
