I have the same problem with my neighbors dogs! Whenever my children, my dh or myself is near the fence they come right up to it and bark like crazy. When I was pregnant with my daughter over 3 years ago my patience was really short and I called my neighbors to complain about it. So they know it's an issue, but they still don't do anything about it. It's been about 5 years of barking! Recently I noticed that if I toss a stick over the fence it quiets them down. The stick must be exciting for them. Dumb dogs!
