It took seven firefighters who arrived at the scene to figure it out - the dog had gotten onto the roof through an upstairs window.
But getting through that window would have been tricky. "It seemed to be a very agile and adventurous dog who pushed his way out of a window by removing the screen and pushing the window open," Cardinal said. "We suspect the locking mechanism may have been malfunctioning on the window that allowed him to push through."
The firefighters extended a ladder, and lifted a man to the roof. But when he tried to catch the dog, the dog got scared and backed up toward the window.
