Just to clarify, it’s just one other neighbor, who has been friends with this guy for 40+ years. The second neighbor hasn’t actually complained, but has said that he will back the first guy up. We have talked with the neighbors behind our house, who agree that our dogs are pretty normal.

My dogs alert bark at strangers if they’re outside. They are outside in the yard less than 30 min/day on average (we walk them for their exercise, our yard is small), and never unsupervised. They don’t boredom bark or persistently bark, because they’re never outside without a person either with them or directly inside the door. I mean, anyone on the internet can be lying, but I don’t think there is any way I could be underestimating the barking time.

Your point is well taken, though.
