No barking zone. The Ultrasonic Indoor Bark Control device is designed to emit an ultrasonic tone that helps to disrupt nuisance barking without the use of a bark collar. The high-frequency sound affects all dogs within hearing range--up to 25'--even in multiple rooms. Place the device on a table or mount it to a wall and bring a little more quiet to your home.
