Nicole, is it necessary for the puppies to learn about stairs? Do any of their adopting families have stairs in their homes? Maybe that is something they will begin to learn after they go to their adopting families? I have such mixed emotions now when I read your posts about them because I know they will be going to their adopting homes and families sooner rather than later. They are just so, so cute. I got the summer members' mailing for Brookfield Zoo - it has a picture of our newest polar bear cub and his mom on the back cover - and I thought of Sheena and the pups!
