Outdoor Ultrasonic Dog Anti Bark Stop Barking Control Deter Black

How does it work? When the Outdoor Bark Control is within range of constant barking, and internal microphone picks up the sound and the unit is activated. The Outdoor Bark Control emits an ultrasonic sound. The ultrasonic sound can only be heard by the dog. Startled by the high-pitched sound, the dog should stop barking, as it will associate its bark with this unpleasant noise. The Deluxe Outdoor Ultrasonic Bark Control System can hang in a tree, at home anywhere in your yard, whether it is hanging up or free-standing on a table or other area. The Deluxe Outdoor Ultrasonic Bark Control system has a power indicator and can be set to 'Off' to conserve the battery when you're away. Batter operated(9-volt battery not included)
