How the PetSafe Deluxe Big Dog Bark Collar Works:

Place the PetSafe Deluxe Big Dog Bark Collar on your dog. When your dog barks, a harmless Static Correction is emitted. There are ten levels of correction. The bark collar automatically adjusts the level of static correction to your dog's temperament. The Temperament Learning Systems uses sophisticated software to track the number of corrections needed to reduce and in most cases eliminated nuisance barking.
