PATCHOGUE, N.Y. – Stephen Neira says he wanted to give a dog a second chance at life.

Newsday says Neira bought Alex, a pit bull mix, on Thursday after seeing him on a website of pets “on death row.”

The site claimed Alex had been through behavioral tests and was deemed “sociable.”

His behavior was classified as “average.”

“Alex did not show any concern during the handling and resources of the behavior assessment but he showed a bit of concern inside the shelter. When he’s off leash, he is friendly with other dogs. But when he is on a walk or when he’s in the kennel he showed barrier frustration and barks at other dogs. The behavior department feels that he can go to an Average home,” Alex’s profile on Urgent Pets on Death Row said.

“They made me feel confident enough that I could bring this dog home to my family. They made me feel confident,” Neira told News 12.

Alex was scheduled to be euthanized 22 minutes after Neira arrived at the Animal Care Centers of New York City.

Neira says that he immediately took the dog on a walk before bringing him home to meet his family.

“He ran up to the back door, wagging his tail. The kids were there with their iPads taking pictures,” he said. “When I opened the back door, he shot all the way through the house straight to the living room and then all the way back. And on his way out, my oldest girl was standing in the corner and with no hesitation, no sniff, right from running, jumped right in to go for her, right at the face.”

Neira says Alex’s teeth pierced the girl’s face and arm.

“After I threw the dog, I thought it had passed out from me choking him. He bounced right back up and pinned me up against my own gate,” Neira said. “I fought with him there, kicking him, trying to keep him back, and finally my neighbor opened the gate, grabbed me and pulled me out of the gate.”

After being tranquilized by police officers, Alex was euthanized.

According to Newsday, city shelter documents have conflicting information about his past, saying he was a stray and that he was muzzled when surrendered by his old owner.

“Our thoughts go out to the family,” a city shelter spokeswoman said in a statement to the website. “In the meantime, we are investigating this case for further details.”

Neira says that he hopes shelters will do more thorough behavioral tests before allowing a dog to be adopted
