Features:
Ultrasonic anti-barking device can automatically detect dog barking from 50 feet away. The bark control device automatically emits high-pitched sounds that only dogs can hear. After the dog stops barking, the ultrasonic bark control will automatically stop emitting ultrasonic waves.
Ultrasound is harmless to pets and completely inaudible to human ears, so the device can be used safely
Can be hung on trees, indoor, outdoor walls or fences to prevent dogs from barking (in range). When excessive barking is detected, the microphone will respond to the barking and activate the component.
