It is really useful. My dog ​​barked at any animal that was on TV. Now he goes on alert, but he no longer barks or is as nervous as before. It's a fantastic invention, especially for my neighbors. You just have to adjust it to the frequency and place it near your dog. When he starts barking it quickly activates and emits an annoying frequency for him. It doesn't hurt him, and he quickly gets used to it.
