Noodle preferred to sleep in his ex pen. M and E, our chihuahuas, slept in a bathroom where toddlers could not bother them. But now the kids are old enough to be trusted. Blueberry has been sleeping in a crate which we move from room to room depending on which kid wants him for the night. It works fine for him but isn’t the most fun to move. I would love to teach him to sleep in a bed on the floor, probably when he is done teething. Any ideas about how make the transition?
