The fight over a tiny purebred pooch is brewing in the Bronx.

One family, which lost the dog, says another family wrongfully changed her micro-chip registration, and refuses to return her home.

Kylea Lester says it should be an open and shut case: a family dog lost in June, and then found by a total stranger in a Laundromat, all on video.

"That's my dog," Lester said.

But a street encounter with that stranger a few weeks ago led to a confrontation, which then led to harassment, petty larceny, and other charges being filed against Kylea.

The 18-year-old says she was just trying to get her dog back, but now she's also trying to clear her name.

"I was pushing just to get the dog back, and for the case to be dismissed," Lester said.

Criminal case aside, attorney Jenay Nurse says the Lesters have a mountain of paperwork to prove the dog, named Ivy, is now living with the wrong family.

"We want an outright dismissal," Nurse said. "We want them to admit they were wrong, that they arrested Kylea for stealing her own dog, that the ownership of the dog is not in question here."

The Lesters have Ivy's original AKC papers, vet bills, and a matching serial number to a microchip implanted in the dog's neck.

"We have tape to prove it, we have papers to prove it, we have tags to prove it," Nurse said. "I don't know what else they need."

But records show a woman identified as Deneen Williams now has her name on Ivy's chip registration.

On the phone she acknowledged that her daughter and son-in-law found the dog in the Laundromat, and in the following days paid for the chip re-registration after no one claimed the dog.

Asked if her daughter would now be willing to return Ivy, given the Lester's original paperwork, she did have one condition.

"They need to give my daughter her money back, and then they can have back the dog," Williams said.

After taking another call, Williams got back on the phone and retracted the statement.

"She's gonna keep that dog," Williams said. "We're gonna fight to the end."

The Bronx DA's office, which is moving forward with its criminal case against Kylea, says its investigation is ongoing.

Kylea Lester left court Friday with a host of criminal charges filed against her and a trial set for September 5th – but without her Yorkie Ivy.

The Lesters say they intend to file a criminal complaint against Ivy's new family, while they wait for the start of their trial, to get her back.
