Worked on the first try. It makes my dog stop barking immediately. Highly Recommend to anyone who has a difficult time with loud noises.

Stops them from barking when people come to the door or when loud sounds go off when watching TV. My wife and I both carry one to go on walks if they run away or start to eat stuff off the ground. Stops them every time. Would 10/10 recommend!

I was suspicious at first since my pom just does whatever she wants. But she really reacts well to it. She looks at me and knows that it means she's doing something wrong. I hardly have to use it now. I just pick up the remote and she looks at me.
