She quickly grabbed her infant and toddler and called on her 12-year-old son to get the other children out of bed and out of the house.
Within minutes, everyone was outside, including Capone, and soon the house was engulfed in flames.
"We always do a roll call every time we get in the van," Fullmer told the Des Moines Register. "They're used to it."
The family lost everything in the fire, but escaped unscathed thanks to Capone.
Fullmer’s husband is a truck driver and rescued Capone about 18 months ago from the side of a highway.
“He’s pretty special,” said Fullmer.
The family entered Capone into the American Humane Hero Dog Awards. If you would like to vote, click here.
