Ultrasonic Anti-Bark Device is an electronic device that produces an ultrasonic high-pitched sound which canines find irritating but inaudible to humans. It is 100% harmless to dogs and safe to humans. Cats are also susceptible to the high-pitched sound. This device is used as an alternative to other bark control methods such as shock collars and vocal cord surgery. It can be powered by either battery or by Alternating current (AC). The use, possession, and ownership of this device are legal in all 50 states and can be purchased locally or online. Prices range between $18 to $85. There is no licensing requirement to possess this product. The device comes in several versions: collar worn, standalone and handheld. The collar-worn and stand-alone versions are activated when internal microphone picks up a constant barking sound from the dog, while the handheld is manually engaged. Some models come with multiple noise level settings to maximize its effectiveness. It can work at a range of 50-100 feet away from the barking but the high-pitched sound will not penetrate any solid objects such as concrete walls, wooden fences or windows. Here are a few examples its uses: To train, you’re puppy not bark or deter unwanted behavior, to teach the next door neighbors dog not to bark without the owner knowing it, and to stop the neighbor's dog from barking
