I let them out of the puppy pen twice a day so they can run around more. I have to be there when I let them out, though. I'm afraid a hawk might grab one. They come in at around 6 and I set up their pen on puppy pee pads for the night. Boy oh boy to they pee and poop. As soon as I wake up I set their pen outside so I can shake out the puppy pads and put them in the wash.
