Actually, this punishment is still too mild. Unfortunately, it happens again and again that dogs go crazy because their irresponsible owners let them run around unleashed. It has happened to me more than once that the dog of some idiot suddenly ran after my bicycle. The good thing in America is of course that you can really let off steam with the irresponsible person and call them anything you want. As long as you don't get physical, everything is allowed. The first amendment of the constitution guarantees it.
