Bring peace and quiet to your home with the Multi Room Indoor Bark Control units. Simply place the devices in the rooms your dog barks in the most. You can attach them to a wall, door frame using the adhesive-backed hooks or just place them on a table. The devices detect whenever your dog barks and they emit an unpleasant ultrasonic tone that's inaudible to most humans. Your dog will learn to associate barking with the high-pitched sound teaching him to stop barking. Most dogs bark less within a few days.
