Diane Urquhart says her dachshund JoJo alerted the family to an electrical fire in their mobile home.
The Washington state woman tells a local paper the little wiener dog started barking the other night.
JoJo also tried pushing 11-year-old Kalen out of bed.
The couple and three children were home at the time.
The Urquharts say they rescued JoJo from the water in a local park when he was a puppy.
Now, they add Jojo has returned the favor.
