Designed for large dogs with up to 34 inch neck size, the PBC00-11047 has two primary features created to shorten the training phase and promote good behavior. The bark control collar has a unique patented sensor that provides the most reliable bark detection available. Using both vibration and sound sensors to discriminate each bark from other external noises, a static correction is adminstered to deter barking. The patent pending Temperament Learning system from PetSafe, contains software that trac ks the number of corrections needed to substantially reduce (and in most cases eliminate) the number of nuisance barks. Once the dog has learned to reduce the barking, the corrections are reduced. This system also includeds the QuickFit buckle to provide a perfect fit and quick release every time.
