If you ever want to practice calling 9-1-1, you may want to unplug the phone first.

Sylvia D'Antonio, 46, of Lake Parsippany, New Jersey, was charged with disorderly conduct for making three late night 911 calls.

But she insists the calls were made by Slayer, her German shephard, reports the Asbury Park Press.

A police dispatcher was alarmed because when the calls were picked up "the only communication was someone breathing".

The calls were traced and three squad cars raced to D'Antonio's home where they found there was no emergency.
