So the dogs upstairs and next door will sometimes bark because they think they hear someone crossing the street nine blocks away. And then they think the other dog is barking at them, so they bark back and forth for… well, in this case, from about 8:00 until right now.
I’ve spent the last several minutes playing ultra high frequency tones through my monitors with my window wide open. The dogs seem to have shut up, but I have no idea if the tones had anything to do with it. I just hope it was really irritating for them.
