Hey Steve,
I fully understand about non stop barking.
I have a couple of dogs next dog.From my bedroom window to where they liked to bark the best is 20 feet.
The aholes next door put them out at 5 am and leave them until close to midnight.
Those phucking dawgs would start barking and not stop for hours if they just thought they heard a butterfly fart in the next county.
I was getting real close to doing something to the dogs I knew I would end up regretting. If I got caught.
I did a search for
ANYTHING that might help.

I FOUND IT !!! 
It is called Super Bark Free.I noticed a difference within 15 minutes. Same dogs are next door and they are not any problem anymore.They now only bark when they really should bark.
