A family rushing to escape the deadly California wildfires left their dog behind — but the pup was found days later, alert and guarding the last home standing on the block, according to a report.

The Copsey family didn’t realize how swiftly the deadly Camp Fire — named for Camp Creek Road in Butte County, where it sparked — was moving when they evacuated their home in the Northern California town of Paradise.

“I thought it was raining,” mom of three Leahna Copsey told the Visalia Times Delta about the moment she first noticed the dark clouds over her home. “I went and put my hands out and charcoal fell from the trees.”

Seeing the soot got Copsey moving and she quickly packed a couple of supplies and got her two daughters, 10-year-old Emma and 8-year-old Clarisa, into the car.

Amid the chaos, it was unclear where their border collie, Ella, was. Copsey thought about the pup and hoped for the best — but they had to go, she said.

The family managed to escape to Lake County, nearly two hours away. Soon, as they started hearing about the devastation of their town and the area, they found out their house had burned to cinders and feared that Ella was gone.

Then, two days later, a friend who’d been able to go back to the evacuated area saw Ella through the haze, sitting in front of the Copseys’ next-door neighbor’s home.

“She was protecting it,” Copsey said. “She was protecting the only house left on the block.”

Ella had burned paws and was exhausted, but she was otherwise OK. Copsey’s eldest daughter, Kayla Westman, is taking care of the pup and treating her burns.
