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.
