From the Buck's County Courrier Times (PA):
Three members of a Doylestown family had enough warning to escape injury Wednesday morning after a pet dog and a smoke detector alerted them to a fire in the basement.Deb and Vince Prendergast and their granddaughter, Haele, were able to get out of their Chubb Drive home safely after the fire started at about 7:30 a.m.
The Prendergasts credited their son's dog Moose for alerting them shortly after the fire started by barking and scratching at the couple's bedroom door, according to Larry Browne, an assistant public information officer for the Doylestown Fire Co.
"The smoke detectors had something to do with it," Browne said. "But they're putting some credence in the dog (helping to alert them to the fire)."
After the dog woke her up, Mrs. Prendergast woke her husband and granddaughter, dialed 911 and all three left the house.
