BRENTWOOD -- A farmhouse was heavily damaged by fire but its residents were able to escape safely thanks to an alert pet and smoke detectors, the East Contra Costa Fire District said.
The one-alarm fire was reported about 12:30 a.m. at a single-story home in the 7000 block of Lone Tree Way. Firefighters arrived to find smoke and flames shooting out of the home, said Battalion Chief Jake Gonzalez.

"It was coming through the windows and doorways," Gonzalez said.

A woman living at the home was awakened by a family dog, Gonzalez said. When she got out of her bedroom, she saw waist-high smoke and the smoke detectors started sounding.

She tried to get a garden hose to put out the fire but soon realized it was too serious and instead went to help her elderly mother out of the house.

Both got out safely and were treated for minor injuries, including smoke inhalation and minor cuts and scrapes, Gonzalez said.

The fire was extinguished within 20 minutes. The dog that alerted the residents survived, but a second family dog died in the fire.

The home sustained major damage and was uninhabitable, but a cost estimate was not available. The cause of the fire, which may have begun in a living room, is under investigation.
