It uses a 9-volt battery as a replaceable battery, and you need to plug it into the device. With the aid of an internal microphone, our outdoor ultrasonic bark control device is automatically activated when it detects barks up to 50 feet away. It then emits an ultrasonic sound. On hearing this high-pitched sound, the dog immediately stops barking as it will associate its bark with this unpleasant noise. When the dog stops barking, the ultrasonic sound also stops.

Note: Battery is not included in the package.

The average human hearing frequency ranges are 20 Hz to 20 kHz, and dogs can hear from 15 Hz to 120 kHz. Our mini bark control emits ultrasonic waves at 25 kHz, so the sound doesn't affect anyone. Ultrasound does not impose substantial penalties on the dog, 100% safety for you and your dog.

Two LED indicators can test battery status.

3 adjustable ultrasonic volume levels

Mode 1: Low range (up to 15 feet);

Mode 2: Medium Range (up to 30 feet);

Mode 3: High Range (up to 50 feet).

The dog bark control housing is UV resistant, waterproof and durable, and can withstand every weather condition. It is a lightweight, cute design, suitable for outdoor decoration. It can use indoors (not recommended, if you need to use the recommended indoor startup mode, please use level 1).
