Anti-barking device, improved dog bark control up to 15 meters, 3 adjustable sensitivity/frequency levels, rechargeable ultrasonic anti-barking device

[Improved Dog Training and Behavior Aid Tool]: Using the latest ultrasonic technology, the anti-barking device automatically emits a high-pitched tone that only dogs can hear. It automatically detects a dog's barking, and once the dog stops barking, the ultrasonic bark controller will automatically cease emitting ultrasonic waves.

[Anti-barking for All Sizes and Breeds]: The anti-barking device has 4 sensitivity levels to choose from. You can use the most suitable equipment to define the environment, select the detection distance, and adjust the sensitivity to achieve your goal. Level 1 is the least sensitive, and level 4 is the most sensitive.

[Safe for Dogs and People]: The dog bark control device has no electric shock, no irritating odor, and no beeping, making it safe for both animals and humans.

The anti-barking device will automatically emit ultrasonic waves to prevent dogs from barking, which is perfect when you leave your dog alone while you're away. Dogs remain calm, creating a peaceful environment for you, your family, and your neighbors. If the dog has difficulty hearing or is aggressive, the device may not work as intended. [USB Rechargeable Dog Bark Control]: Rechargeable anti-barking device with an indicator light for effortless use. A 5-hour charge lasts 30 days, saving you the hassle and endless expense of batteries. No need to install batteries; it works right out of the box. (It is recommended to fully charge before use for best results.)

[Stop Dog Barking Indoors and Outdoors]: Tested, the anti-barking device works best within 32 feet, completely freeing your hands compared to traditional dog trainers. You can easily train your dog's behavior by turning a knob. Ideal for preventing neighbors and stray dogs from barking outside.
