We have an obnoxious woman that lives next door who has a Great Pyrenees that barks all night sometimes. That low pitched bark really carries. I’ve had a few words with her about it with no effect, so I’m taking a different tact.
My son — who is an actual rocket scientist — is building me an ultrasonic sound cannon that will send a 200W 24K-30K Hz tone toward the offending dog’s direction. We haven’t tested it yet, but I’m hoping it works.
The alternative is a stray gunshot or dognapping...
See Elaine Benes and Kramer about the dognapping....they're experts.
