We have tried a couple other devices that were suppose to stop the barking, but, your device Bark Mute is the only one that actually works. We didn't want to stop all of her barking, like when she needs more water or to go out, we want her to tell us. We have used the device a couple of times and our pup is actually listening now when we ask her to stop barking. We really like that it does not shock her, but, she is surprised instead and reacts to the surprise by stopping to bark.
