Fancy began barking as flames quickly ate through the home's roof.
"She just kept barking and I got up and come in there and she was looking up at the attic where we have the ladder and kept barking," said Virginia Falls, Fancy's owner. "I walked up the ladder and when I pushed the thing up to look, the whole attic was engulfed in flames."
The father, mother and two children got out safely, but the parents suffered minor burns and smoke inhalation.
Emergency crews had a tough time getting to the scene because of icy roads. The house was a total loss.
It was not immediately known what caused the fire.
