The results were magical.

Two neighbors, six big dogs, the owners oblivious or always at work - the barking was nonstop and the noise was horrific. At my wits end, I installed the Dog Silencer Max. The results were magical. Within a day the barking was noticeably reduced. Within a few days barking became sporadic. Now, after just a week, barking from the six big dogs is only an occasional occurrence. The Dog Silencer Max is just as advertised - we can use our yard again. Great purchase! Great product!
