My parents' chihuahua, Nacho, is a hero.
Apparently today at my parents' house, there was an incident. My mom was watching TV and getting ready to take a bath and go to work, when Nacho started scratching and barking at the basement door. My mom thinks the cat is behind the door or something, so she opens it. Black smoke starts billowing up the stairs. It turns out that my parents' dehumidifier had caught fire and it was flaming up good. Not sputtering but HUGE flames.
My mother grabbed Nacho and ran outside (apparently leaving the cat to fend for herself) and called the fire department, who promptly sent a cop with a fire extinguisher followed by the engine. She ran inside to move her car for the fire truck and couldn't see for all the smoke. This is how bad it was at this point. Imagine if she'd taken a bath and left.
So... Nacho, the 4lb chihuahua, saved the day.
