Allinfun, you just described our Yorkies perfectly! I'm reading all these posts wishing I could take ours, or at least one of them, shopping with me but they would bark and jump and have way more fun than they should.
One day I took our biggest Yorkie, FiFi, on a short shopping trip. She had never been to PetCo and she had a blast! Then we went to Subway and I brought a sandwich to the car that we shared. We had "girl day"!!!
