We have a dog next door that barks day and night. Owner won't do anything about it.

I have heard there are devices that you can set up near the fence, and when the dog barks, it emits an audio signal that hurts their ears but is too high for humans to hear. The idea is to train the dog to stop barking.

Anyone heard of such device?

Thanks in advance.

You made me think of a possible solution. I have had an occasion
to install a high frequency buzzer (3000hz) into a 6 foot x 4 inch PVC
tube. Believe it or not if you insulate the butt end of the tube the
sound will almost disappear completely unless you are in the path of
the end of the tube. I believe the buzzer I had was 90db at a foot and
required just .003 amps at 12volts. Sound at this high frequency
requires a minimal amount of power, so you can leave it running
continually without any real cost.


My suggestion for you is to find a 20000hz or more buzzer that you
can't hear and mount it in a PVC tube of the appropriate size. Aim it
and wait for the dog to commit suicide.
