The Deluxe Bark Control collar will never mistake anything for your dog's bark except, well, your dog's bark. The patented design requires both the sound of your dog's bark and a tangible vibration from the bark to occur at the same time before it corrects your dog. Every other anti-bark system available triggers off one or the other, but not both. Simple to use. Just turn the battery to the "on" position, put it on your dog, and select the correction range you want.
