This adventurous pooch isn't the first to venture out on the roof, or at least try to. This past October, a Great Dane attempted to clamber onto the roof through a skylight. He made so much noise doing it, his 18-year-old owner (who was inside the house at the time) called 911, thinking a burglar was trying to break in.
