Video shows moment dog starts house fire after chewing on lithium-ion battery

Video shows the moment a dog accidentally started a house fire in Tulsa, Oklahoma, by chewing on a lithium-ion battery that sparked the blaze. 

The footage, recently released by the Tulsa Fire Department, showed how the fire began after a dog bit through the housing of a portable lithium-ion battery power bank intended to charge cellphones. In the clip, the pet was seen biting on the battery while another dog and a cat rested nearby, until sparks begin to fly out of the battery. The fire continued to grow as the confused pets appeared to panic. Officials said the animals were able to leave the home unharmed.

"While the home was significantly damaged, their two dogs and cat escaped the home uninjured through a dog door," Tulsa fire authorities said.
