Promising review: “This works great! I have two mouthy German shepherds. One who constantly barks at the fence at our neighbor’s dog next door. The first day, I went outside and had the neighbor bring her dog to the fence, and as soon as my dog started to bark, I pressed the sonic button, and she kind of looked around like, ‘What was that?’ Because she stopped barking, I gave her a treat. For the next couple of days, I did the same thing every time she started to bark: I pressed the button and gave her a treat. I’ve only had to press it a couple of times each week now because she thinks about it before she starts to bark, and when she does that, I give her a treat. I have been putting up with the barking for three years and, even with a trainer’s help, could not figure out what would work to get her to stop. This product worked amazing, and I’m so happy that I tried it.” —esor0210

Btw, this device comes from a small, family-run business called NPS!
