Oh, Gigi just reminded me - we do normally hold her hand too, or even carry her a bit, but if she is walking, and decides she wants to go look at the puppies, no matter how tight I try to hold on to her, her hand is out of mine, and she is running down the middle of the concourse towards the pet store, and there is no way that I would be able to keep up with her, and be able to dodge all of the other shoppers! So Puppy Pack comes in very hand there!
