Because we have not slept in past the rising sun since, well, since Deedee came home. As soon as the dimmest of the sun's first rays slap that little puppy in the face, she immediately becomes alert, and comes to play tic-tac-toe on our collective faces. Sasha, miss internal-alarm-clock, also will let us know if it's past her mealtime if it gets too late. Cleo is the only pug that's happy to sleep in and cuddle.
Rikki and Bunni are, unfortunately, solidly in the Deedee camp.
