The puppies love sitting out on the hot tub in the evenings. It's out on a landing outside our bedroom and looks as though it's on the roof of our house. I often find Loki laying with his head hanging over the edge of the roof, looking at... something. Lyla likes to spy on the squirrels.
Just wait puppies. Only a few more months and it will be cool enough for me to actually sit IN the hot tub. Then you'll be out of luck.
