answer:This is a question I’ve been asking for years. Surely it can’t just be for protection. I have the same problem, though not as bad as yours. The two big dogs next door hurl themselves at the fence whenever I go into my front or back yard and bark on and on at the slighest sound, even the raising of my window upstairs. One time they dug under the shared back fence, raced up to my back door (which is glass) and barked and snapped at me until his owner could retrieve them. I’ve never talked to that “neighbor” since.
