My neighborhood is plagued with fence-aggressive dogs. The kind that run along next to me growling, snarling and foaming at the mouth. It's terrifying. There's no way those fences would actually keep the dogs in. I love dogs, have one of my own, and our evening walks can be hellish because of it. Some dogs actually jump up and hang over the fences, snapping and snarling. It's getting harder and harder to find a safe walk route. Does anyone have any suggestions on what to do? Other than move, which is not an option right now. Do those ultrasonic bark stoppers work? I called animal control, and they said as long as the dog doesn't leave the property they aren't doing anything wrong.
