Two women abandoned a poodle mix in bloody bandages, and it turned out to be a dog missing for almost two years, Nassau prosecutors said in seeking the pair who left him outside a veterinary office.

Niño had exposed bone and flesh, skin lesions and other injuries when an employee of a Hempstead animal clinic found him lying on a small bed outside the entry about 9 a.m. Tuesday, the Nassau district attorney's office said Wednesday.

Surveillance video showed the two women walking on Main Street about 8 a.m., and one of them, who was pushing a cart, disappeared from the camera view, then returned with what appears to be a wrapped package.

She left the package in front of the Main Street clinic, then quickly walked away.

A microchip in the dog led to his owner in Uniondale, and she said he had disappeared from her yard almost two years ago, according to authorities. She received Niño in 2000 as a birthday gift from her daughter, officials said.

Niño was treated at the Hempstead Town animal shelter and then taken to a another private veterinary facility where he will be reunited with his owner, prosecutors said.

Authorities now want to find the two women, whom they consider "persons of interest."

The district attorney's office declined to give more details, saying investigators are looking into whether the dog was stolen.

Prosecutors said anyone with information on Niño's case could call the district attorney's animal crimes unit at a 24-hour tip line, 516-571-7755, option 8.
