Never thought about going to a pet shop. Great idea! I've also thought about putting a baby bottle and rattles on the puppy purse to make it look more like a diaper bag, which is closely resembles, with their blanket hanging over the top (baby girl blankie). We recently traveled a long distance and I didn't have a problem sneaking the girls in the puppy purse. It's pretty tight with both in one bag and both not wanting to hide. I kept laughing because they did not want me to zip the top. I walked right by security at a rest stop and they did not say a thing, but it was around midnight. Mommy has learned to hold it longer than them! lol
