The owners of the Mooseau home in the Warm Springs area of Ketchum were away from home Friday when a fire broke out in an upstairs office. Unfortunately, their dog was in the house, and by the time firefighters were able to search the residence to find her, it was too late.

"Despite heroic resuscitation efforts by firefighters, the dog did not survive her smoke inhalation injuries," Ketchum Fire Chief Mike Elle said in a written release.

The home, at 211 Log Chain Lane, was reported on fire at 1:55 p.m., and when firefighters arrived, they found flames coming out of an upstairs window and heavy smoke coming from the roof. An interior fire attack that included units from the Sun Valley Fire Department and Wood River Fire and Rescue had the fire under control by 2:30 p.m. and out by 7:10 p.m.

A total of 11 units and 36 firefighters responded to the fire.

Preliminary investigation indicates the fire started with an electrical short in the office, but further investigation is continuing.
