I have been teaching the pups to "wait" whenever it's outside time, so that I can walk out the door in front of them (the whole alpha dog thing). Allie has picked up on it pretty quick and when I ask her to wait, she will back ip and lay down until I say okay, come.
Here's a video of her "waiting". It's so funny because no matter where she is when I say wait, she goes to the same spot to lay.
