I've noticed my neighbors, not all, but enough to that its noticeable, will not walk down the sidewalk next to my house when my dog is out. I watched someone one day cross the street to the other side without a sidewalk when they were walking to a neighbor's house, and then they did the same on the way back, only crossing to the sidewalk when safely past my fence. My dog barks at anything that moves. I thought about putting up a sign saying "Beware of Dog," but I have mixed feelings about it. I'm a common sense person, but legally I know there needs to be a sign in just in case.
