I must admit, I have snuck Derby into places that don't allow dogs but no one even notices when I have him in a bag. I just can't leave him in the car if it isn't safe or if it is too hot out or if I'm going to be any longer than 5 minutes. He goes everywhere with me. I too, have also taken him into the movies with me once....I won't do it again but it was perfectly fine and no one else knew.
