When conditions changed, firefighters were forced outside to battle the fire.

“There was a report that we may have had some structural failures, so they came back to do what they call a ‘defensive attack,’ so hitting it from the outside,” said Robin Widner with the Falcon Fire Protection District.

Firefighters saved a dog from the backyard during the fire.

The cause is still under investigation.
