Using the adhesive-backed hooks, simply place one of the devices on a wall, door frame, or table in whichever room your dog barks the most. Whenever your dog barks, the device emits an unpleasant ultrasonic tone that's inaudible to most humans. Your dog will learn to associate his barking with the high-pitched sound and stop barking. Most dogs bark less within a few days. The deterrents are available in single or dual packs for homes to cover multiple rooms. Ultrasonic bark correction is often the best bark control solution for many dogs. However, it will not work for all dogs because of factors like age, hearing ability, and temperament. When setting up the device, make sure there are no obstacles between the dog and the device. Also, make sure that the speaker is less than 10 feet high and is facing the direction of the barking dog.
