A dog is credited with helping save a couple when a fire broke out in their far east-side home early Sunday morning. 

The family dog, Reilly, alerted the couple to a fire that started in the garage of a home in the 10500 block of East Dusky Willow Drive, near South Houghton and East Valencia Road around 1:30 a.m., Capt. Barrett Baker, a Tucson fire spokesman said in a news release. 

The couple and the dog safely escaped from the home. 

When crews arrived, they found three vehicles in the garage on fire, the release said. 

The fire spread to the attack of the house, but crews were able to prevent it from spreading through the rest of the home. 

The fire was extinguished in less than 20 minutes. 

Nobody was injured. 

Comments disabled.
