One morning when I had to let the puppies out early, had it snowed at night. They now know how to get out the door and down the chute. But they slowed down quite suddenly, when they stepped in the snow. It looked really fun. However, it was quickly just something that made it more fun to be out in. The snow did not last long, but we got snow a few laps. Then we have also tried to have puppies in snowy weather 🙂
