I've lived in my house for about seven years now, and my neighbor's dog has always had a habit of barking in the middle of the night, every ten or fifteen minutes. Now I have a sixteen month old son and I seem to sleep lighter or something, so I wake up every time this stupid dog barks. My neighbors keep it in their carport, which is right next to our house and it really echos. We've talked to them about it a couple of times, and each time they say "Oh sure, we'll take care of it" and we don't hear the dog for awhile, but it always starts up again.

It's not incessant barking, but it's enough to wake you up ever fifteen minutes until you get to the point where you can't sleep at all. Does anyone have any suggestions short of poisoning the damn dog? I'd love to do something equally annoying, but not something illegal. What do you think would make them really get the hint? I can't do anything that involves noise as it would wake my little boy (since the dog does that).
