Smart neighbors!!!! I for one know the hot wire works very well on dogs. I have horses and on occasion my dogs will get lifted on the bottom wire when their tails touch it. It takes weeks before they will go near the fence again. I even trained my hound to an electric fence dog yard cause she refused to stay in the yard and had to rig up something while I build a dog yard. She ran straight into the fence got lifted and I couldnt even get her out that door for two weeks. She never tested it again.
