The SportDOG No Bark 10R 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 the 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. For use in the US only. This unit is compatible with all US 110v outlets and are not to be used with 220v international voltage.
