Hi, I'm really hoping for some training ideas from you guys! Here is my problem... I take Chewy to work, I work in a retail store in an outdoor mall. I have a door that stays open, and Chewy was doing great about not going outside (he follows me around like a shadow). Anyway, the only problem is when another dog goes by, he wants to run out to check out the dog. I started using a can with coins, and that was working well. It would distract him and then I would tell him no and stay. Well, lately he completely ignores the can and he just runs out and if the dog doesn't stop, he'll follow. I chase him like a madwoman. I'm just afraid one of these days it might be a mean dog, or he could take off and run into the nearby street. How can I keep him from doing this? My husband thinks maybe I should put him on a leash in the store, but I love that he can run around in the store and greet customers, I just don't want him to go out of the store. Any ideas?????
