WATCH: Oklahoma dog ignites house fire after chewing on lithium-ion battery

A video released by the Tulsa Fire Department in Oklahoma shows a dog unintentionally starting a house fire after chewing on a lithium-ion battery.

In the video, two dogs and a cat are seen from an indoor monitoring camera in the home's living room. One dog begins chewing on a lithium-ion battery pack until it explodes and the house catches fire.

The subsequent fire was put out by a quick-acting fire department. All the pets escaped the burning home through a dog door.
