I am surrounded by neighbors who let their dogs bark day and night and who don't care about their neighbors, nor the CC&R rules of our HOA. Talking to the neighbors has been a waste of time. This has been going on for about 10 years with the HOA nor the City of Las Vegas willing to do anything about it. I tried different dog barking silencers and then about 6 years ago bought these. It took a while, but the dogs finally started to stop barking when the Dog Silencers would sound. Out in the desert sun for 6 years, 1 of them started to work intermittently so I bought 2 more, replaced 1, and installed 1 on my side of the block wall set on automatic. That really shut those dogs up fast. The range on the manual transmitter is also excellent. Try these. They work.
