The PetSafe Deluxe Little Dog Bark Collar uses both vibration and sound to ensure only your dog's barking is detected and not guitar hero on the TV. As he barks, he receives a safe "static" training correction. The bark collar begins with low corrections, but if excessive barking continues the correction intensity will increase to properly train your dog not to bark needlessly. When used correctly the bark collar significantly reduces (and in most cases eliminates) nuisance barking.
