PetSafe Big Dog Deluxe Anti-Bark Collar

System Includes:
• Adjustable collar for neck sizes up to 86.4 cm (34”) with the QuickFit™ buckle
• Battery (PetSafe® RFA-188)
• Operating and Training guide
How It Works:
Place the PetSafe® Anti-Bark Collar on to your dog. When your dog barks, a harmless Static Correction is emitted. There are 10 levels of correction. The collar automatically adjusts the level of Static Correction to your dog’s temperament. The Temperament Learning System contains software that tracks the number of corrections needed to substantially reduce (and in most cases eliminate) the number of nuisance barks.
Petsafe®’s exclusive Perfect Bark™ technology ensures that only a combination of sound and vibration from your dog can activate the collar.
