Great solution to neighbors barking dog!

My 2 neighbors on one side of me have 7 barking dogs between them. I couldn’t take the barking any more so a year ago I bought the dog silencer and pointed it toward their porches. The dogs barked for about 15 seconds at first but now I get a bark occasionally and they immediately stop. I have 2 dogs as well that are in our yard. As long as the bark control speaker is not pointed at them they show no effect from it. Great solution to neighbors barking dog!
