Moment dog sparks house fire after chewing power bank

An indoor monitoring camera shows the moment a dog unintentionally caused a house fire after chewing on a portable lithium-ion battery power bank.

In the video released by Tulsa Fire Department in Oklahoma, two dogs and a cat can be seen in the living room before a spark started the fire that spread within minutes.

Tulsa Fire Department public information officer Andy Little said the pets escaped through a dog door, and according to local media the family was also evacuated safely.

"Had there not been a dog door, they very well could have passed away," he told CBS affiliate KOTV.
