Ah, the joys of living in the city. NOT. I guess at this point all you can do is file a complaint if the dog bites you or yours. Otherwise they're not going to do anything and the owners probably feel that since the dog can't get out then nothing to worry about. Of course, if it were my kids going by there everyday and being scared stiffless I'd complain to the school about the danger at the location there at the bus stop. A complaint from the school might hold more weight than a complaint about an individual.
