The PetSafe Big Dog Bark Collar was specifically engineered for larger dogs. This collar features Perfect Bark technology which uses a combination of sound and vibration to trigger an electronic correction - unlike other bark collars where correction is triggered by vibration alone. This helps to prevent false corrections common in other models. High tech microprocessor technology gives a warning beep with the first bark. If the behavior continues, the pet will continue to receive the warning tone, along with a correction which will progressively become stronger up through 10 levels of correction. The Temperament Learning System contains software that tracks the number of corrections needed to substantially reduce, or eliminate the number of nuisance barks. The auto shut-off feature prevents excessive corrections by shutting down the collar temporarily if the dog barks more than 15 times within a one minute twenty second period. System includes: Receiver/collar, PetSafe RFA-188 battery, operation and training manuals.
