Once fitted, the PetSafe NanoBark 2.0 will detect your dogs barking through the vibration of the dog's vocal cords, activating the collar to deliver a safe static stimulation. The collar has 10 levels of static stimulation that will automatically adjust as the dog barks.
Variable Pulseâ„¢ technology prevents your dog from growing accustomed to corrections by increasing the number of static pulses before increasing the static intensity, resulting in gentler and more effective bark control. No more worrying if it's too much or too little, now you can have confidence in every correction.
Please Note: As a safety feature, if your dog barks 15 times within 80 seconds, the bark collar will automatically shut off for 30 seconds
