I wish my dogs were like those you see on TV where they obey every command. Unfortunately that is not the case for me. They occasionally get out at night and when they do, they usually bolt down the street. I've put two Pet Blinkies on each dog. Not only does it help protect them from approaching cars, but when the neighbors see them they know they are mine. It's amazing how bright these little things are. You really need to see them to appreciate it.
