DANVILLE-- A woman escaped from an early-morning fire in her home Monday before firefighters arrived to rescue her little dog, a fire official said.

About 3:15 a.m., fire crews responded to calls from a homeowner saying her house off Montego Drive had erupted into flames, San Ramon Valley Fire Battalion Chief Mike Picard said. Three engines, two trucks, an ambulance and a battalion chief totaling 20 people responded to the one-alarm blaze, knocking down the fire at about 3:36 a.m.

The homeowner was in the single-family home at the time of the fire but managed to get out safely, Picard said. Firefighters responding to the scene rescued the woman's little dog, who is also uninjured.

The woman initially refused ambulance transport, but was eventually convinced by neighbors to go to the hospital, where she was treated for minor smoke inhalation, Picard said.

According to Picard, the fire inspector is still investigating the cause and origin of the fire, though the kitchen, dining room and garage seemed to have been involved.

Estimated cost of damage is currently unknown, though the house is currently uninhabitable, Picard said. The homeowner will stay with relatives while work is done on the home.
