No Barking Automatic Shock Control Collar for Medium Large Dog Anti Bark

Description

product description
bark control collar applies a warning tone followed by progressively increasing tone and shock as your dog's barking persist. If your dog is quiet for 30 seconds or more, the bark control collar resets to the mildest correction level. If a second bark occurs within thirty seconds, a more intense tone is sounded along with a short, mild shock. If your dog barks a third time, both the tone and shock are made more intense.
Your pet will quickly learn to be quiet at the mild correction without having to suffer the more intense stimulus.
