Anyone put one of these in and how effective is it? My daughter has 2 dogs and she said one of them can get on top of the fence (6 ft high cedar) and hang there with her front legs over the top barking at the kids next door. Being that the fence on both sides belongs to the other neighbors she can't attach anything to the top. Is there a way to go around the yard and have a spot near the back door so they can go in and out without do a full loop back? Would be a lot easier getting rid of the dogs but I don't see that happening.
