A pet had to be rescued from a Newtown home on Friday when firefighters arrived to extinguish a fire.  Firefighters responded to Hanover Road and found flames in the walls of the house.  All residents evacuated as emergency responders arrived, despite initial reports that one person was refusing to leave.  Multiple dogs and cats were able to get out on their own. One puppy was rescued from the house by a Hook & Ladder firefighter.  No injuries were reported.  Fire officials say bitter cold temperatures and a light snow challenged Friday morning's work. Whiteout conditions happened a few times, with white-gray smoke covering the property and surrounding area.
