  • This device provides you with an effective and humane tool to TRAIN your pets to stop barking faster and with more success. This no barking dog collar will train your dog to stop problem barking.
  • It has two sizes of terminators which you can choose from; short or long points to match the dog's coat type. It is compact and lightweight, weighing only 2 ½ ounces and is stylish as well with a shiny black polyethylene, adjustable collar strap with stainless steel hardware including the ring for a leash.

  • Our bark collar starts the round of graded corrective stimulation with an audible beep warning and then, if the barking continues, a graded stimulus with ten levels of correction is applied. The correction starts with the beep, and then the lowest level and progresses to maximum until the dog understands and barking subsides. Once the problem behavior (barking) stops, then the cycle is reset.

This anti-barking collar is extremely durable. It has a single warning beep that is operated by a microphone dog bark sensor that can differentiate the dog's bark from other sounds. There is a 7 level shock correction cycle that is reset every time the dog quits barking. It is safe for your dog and very effective.
