W: 12.80/11.80KGS Bark Terminator 2, Advanced bark control collar Electronic Anti Barking Collar with Shock & Sound (NEW) DESCRIPTION: TERMINATOR Anti-Bark Electric Static Shock Dog Collar The TERMINATOR 2 first applies a warning tone followed by progressively increasing tone and shock as your dog's barking persists. If your dog is quiet for 30 seconds or more, the TERMINATOR 2 resets to the mildest correction level. In this way, your pet needs only to experience the higher shock levels a few times before learning that the mild sound and shock stimulus is a warning of stronger corrections to come. Your pet will quickly learn to SHUT UP at the mild correction without having to suffer the more intense stimulus. We have found this technique of progressively increasing sound and shock is not only more humane, it is more EFFECTIVE in breaking the barking habit than conventional shocking bark control collars. The technique is only found on the TERMINATOR 2 If bark persistent then tone & shock even more persistent Advantages THE MOST EFFECTIVE BARK CONTROL COLLAR Increasing sound and gradually shock Automatically increases tone and shock stimuli as barking persists.
