Boris, "Happy Mother's Day Ma!!" Oh Boris, you make our days. Even though at the young age of nine months and weighing in at 100 lbs, you still don't understand that you are too big to sit on our laps. I believe Danes "back up and sit on people's laps" because as young pups, we may have them sit on us for a short period of time. As they quickly grow, Danes don't realize they are suffocating their humans because they have always sat on their laps before. Gotta love those Great Danes!
