A pack of pit bulls killed two chihuahuas and mauled a boxer pooch on Long Island while also attacking their owners, two lawsuits claim.

Tom Doherty, 39, said his family’s two 10-year-old chihuahuas, Remy and Bentley, died when Peter Connolly’s three pit bulls jumped their backyard fence and went for their little dogs in Rocky Point.

Doherty said his wife, Corey, 35 — who was four-months pregnant at the time — was bitten on her hand and arm trying to save her dogs.

“They killed Remy while she was in [Corey’s] arms,” said Doherty, who along with his wife is suing Connolly over the August 2016 incident.

A week earlier, a mom was viciously bitten by the unleashed pit bulls in the same town.

A lawyer for Connolly did not return messages seeking comment.
