Two of my neighbors have gone out of town and left their large dogs alone.
The people may be stuck in Denver for all I know.

But, the dogs are barking all night long.

I have called the PD, and they say it is an animal control problem, and to
call them. I have called and left them many messages, but they are off
until sometime after the Holidays, probably early February.

I have Googled under dog barking devices, and all I come up with is those
rated at 25 feet or less.

I want to buy or build something that will make a dog shrivel up in pain for
about two blocks around me. Can anyone direct me to such a device, or give
me the short tour of directions to make such a device?

I know if the dogs will just get some negative responses to their barking,
they will probably quit. But for now, it's about to drive me around the
corner.

Appreciate it.

Steve
