SANTA ROSA (CBS SF) -- A dog died after alerting its owner to a residential fire in southwest Santa Rosa early Monday morning, a Santa Rosa Fire Department battalion chief said.

Justin Kedton, 24, was awakened around 4 a.m. by his barking pit bull, Battalion Chief Jack Piccinini said.

Kedton and his dog escaped the burning home at 1709 Hearn Ave., but the dog went back into the house while Kedton tried to put out the fire with a garden hose, Piccinini said. The dog was overcome by smoke and was found in a bedroom in back of the house.

Neighbors and passersby reported the fire that spread from the back deck and rear garage to the house and attic, Piccinini said.

Firefighters found the house fully involved in fire when they arrived but brought it under control in about 20 minutes, Piccinini said.

There were no injuries and damage is estimated at $100,000. Smoking materials discarded on the back deck are suspected as the cause of the fire, Piccinini said.

A second fire erupted 20 minutes later at 2517 Dixie Place in the nearby Roseland neighborhood in southwest Santa Rosa, Piccinini said.

The fire started in the engine compartment of a Toyota truck owned by 27-year-old Ignacio Gallego, the occupant of the residence.

The truck fire spread to the side yard fence and fiberglass- covered lean-to and into attic space over the garage.

Firefighters from the Coffey Lane fire station in northwest Santa Rosa responded in place of the fire department fighting the Hearn Avenue blaze, Piccinini said.

They arrived in 10 minutes and prevented the blaze from spreading into the house, Piccinini said.

There were no injuries and damage is estimated at $25,000. The cause of the truck engine fire is under investigation.
