The NoBark 18 bark control collar has 18 levels of stimulation to safely and consistently stop dogs of any temperament from barking. With no programming required, you can just turn the collar on, put the bark collar on your dog, and select the correction range you want. The lightweight, waterproof NoBark 18 also features Perfect Bark® technology, providing firm, fair, and consistent correction when it detects both vibration and sound from your dog
The NoBark 18 uses a patented sensor system to provide the most reliable bark detection available. The unit delivers a static correction via the Contact Points only if it detects BOTH vibration from the vocal cords AND the sound of the bark. External noise or another dog.
