I live in the city and we have a hawk that comes around and sits in a tree on the other side of my fence...I never let my pups go out without me even tho our yard is fenced in. The darness thing is tho that hawk will swake like crazy everytime he comes around so I know when he is close and I make the kids go in...They say shinny objects hanging in your trees will keep them away. I love wind chimes so I have a few hanging on my porch and off my fence that are real shinny...My neighbor say she see him on her fence all the time and they have a lil jack russell...I have never seen him on my fence so maybe the shinny wind chimes work
