I don't take her in Coastal when they are selling animals and I never put her on the floor. Same with when we go to Home Depot and any place that allows dogs. She is carried backwards like a football under my arm and peeks out from under my sleeve. She is an awesome accessory with her fluffy butt and green legs dangling next to my purse. I am careful about what she gets into on the counters when we check out since she loves to throw things on the floor and go through the "impulse buy" display near by. She gets treats at drive through windows but not enough to hamper her appetite and she does not like most things that are fried. Her diet is most likely the culprit and I will make sure she is regimented properly.
Sounds like such fun to take her around town with you!
