This type of collar helps your dog learn the difference between good barking (for protection) and bad barking (due to boredom or over-excitement). The collar picks up the vibrations from your dog's vocal chords as they bark. The bark collar senses the vibrations in your dog's throat that happen only during barking. The vibrations cause the collar to send an electronic shock to your dog. Then if the dog continues to bark, they will get a slightly stronger correction. Your dog will quickly learn that barking causes the signal, and that not barking is the way to avoid the signals.
