This is not a shock collar! The Pettags No-Bark collar is a safe, humane and effective solution to help train dogs. The adjustable no-bark collar is like getting two collars in one. With two different modes to select from, the collar can be tailored specifically to your dog's needs. Sound mode releases a high frequency sound that deters dogs from barking. The vibration mode will vibrate every time the dog barks.
