Anti-barking device, improved dog bark control system with a range of 15 meters (50 feet) and 3 adjustable sensitivity/frequency levels

Dog Training and Behavior Aid: Thanks to advanced ultrasonic technology, this anti-barking device automatically emits a high-pitched sound inaudible to dogs. It automatically detects barking, and once the dog stops barking, the ultrasonic device stops the barking. The controller automatically stops emitting ultrasonic waves. Anti-barking system for all sizes and breeds: This device is available in 4 sensitivity levels. You can choose the level best suited to your environment, select the detection distance, and adjust the sensitivity. Level 1 is the least sensitive, and level 4 is the most sensitive. Safe for dogs and humans: This anti-barking device produces no electric shock, strong odor, or beep. Safe for animals and harmless to humans, it automatically emits ultrasound to stop barking. Ideal for allowing you to leave your dog unattended. Keep your dog calm and create a peaceful environment for your family and neighbors. If the dog is hard of hearing or aggressive, the device may not work as intended. USB Rechargeable Anti-Bark Device: This rechargeable anti-bark device features an indicator light for easy use. A 5-hour charge provides up to 30 days of use, saving you the hassle and expense of buying batteries. No batteries are needed; it's ready to use right out of the box.
