Pity Stare

So both dogs are masters of stairs. Bo is still a bit more cautious going down, but they go up and down with the best of them. So now if I'm just making a quick trip to the basement (switching laundry. etc) I have to close the door behind me, otherwise I have to make sure their snoots aren't snooting where they shouldn't be. But when I do close the door on them I get this: I wanna come down too!
