We have taken Ricky (long-haired chihuahua) to Petsmart since he was a little puppy. People always come up and want to pet him or whatever. I would hate to loose that options since it is one of the reasons he is so good with people. Chihuahuas are not always friendly towards strangers but because of the exposure he gets at these kind of stores, Ricky is. He hasn't left any presents at the store but then I have to keep him in the shopping cart so the big dogs don't get him. He does love to "leave his mark" right outside the store though.
