Once you place the device in your desired location and turn it on, it will emit ultrasonic sounds if it detects any barking within 15, 30, or 50 feet, depending on the setting. These sounds won’t harm a dog or stress them out, but it will irritate them enough to make them stop barking once they learn to associate their own noises with causing the ultrasonic frequencies.

With the indoor/outdoor ultrasonic bark control device, you can keep your dog from barking excessively while you’re out of the house without having to leave a collar on them the whole time. You can leave it in your backyard to let your pup get some exercise and fresh air without you needing to keep a close eye on them, and it will stop other dogs near your house from being noisy too (you may want to talk to your neighbors about the problem first or let them know you plan to use this device, but it won’t hurt or confuse their dogs anyway). Placing the indoor bark control device near your home’s entryway is a good way to keep your pets from crowding visitors at the door or going off when they hear the doorbell.
