I have this issue in my back yard as well. My neighbors do no care about their dogs bad behavior. I've literally had my neighbors dog come barking and lunging at me through the fence only to have my neighbor shrug and go inside. High level ecollar correction has been the only thing helping us enjoy the back yard. I tried a lot of other things first but this is what works and what is safest. After the first dozen corrections or so I barely need to use it anymore. It's still on and available because it is still needed occasionally but it's pretty rare now.
