An upstate New York woman, Pauline Waldron, was arrested after allegedly trying to decapitate her dog with a sword last week, authorities said.

Deputies were tipped off to the animal cruelty last Wednesday by the workers at the Catskill Animal Hospital, where the wounded pooch underwent life-saving surgery, the sheriff’s office said.

The dog was left alone for eight hours before receiving medical care, authorities said.

It wasn’t immediately clear who discovered the injured dog.

The sheriff’s office said five other dogs were seized from Waldron’s home.

Waldron was released without bail at her arraignment.
