The New York attorney general's office says a veterinary technician and man and a woman who owned the dog face multiple charges, including aggravated cruelty to animals.
The brown and black pup, named Miss Harper, was brought to the Nassau County SPCA's attention in September. She was missing a leg and both ears, and needs additional medical care.
The Nassau County SPCA sought donations and asked for public help in locating the suspects responsible for the dog's treatment.
Gary Rogers of the Nassau County SPCA says that, despite it all, she's "a loving, playful puppy."
He says the little pit bull is almost ready to be adopted. Applications have come from as far as Australia.
The Nassau County police union is among the donors helping with her care.
"Why should a little puppy go through this?" said Dr. Kim Barlowe, of My Pet's Vet.
You think she would have lost all love and trust in people, but she hasn't.
"She's a very brave little puppy who's gone through a lot, minimal complaints. I think her biggest complaint is 'take me out and play with me,'" Dr. Barlowe said.
The Nassau County SPCA brought her to this vet in Huntington where she has been recovering beautifully.
"We have just about all the pieces of the puzzle together. We know what transpired. We know a good amount of participants here," said Bob Sowers, of the Nassau County SPCA.
Dr. Kim Barlowe says they're trying to get Harper a prosthetic leg, but if that doesn't work they may have to amputate it.
"She didn't ask for this. She didn't deserve this. Nothing. She was just brought into this world. This type of cruelty is something no one ever wants to see. What's sad is we know about her. We don't know about so many others," Dr. Barlowe said.
The Nassau County SPCA has received calls from all over the country from people who would like to adopt Miss Harper.
They say they would like to choose someone though from Long Island because she will need several more surgeries and continued medical care in Huntington, Long Island.
