Petrainer PET852 Dog Bark Collar Electric Shock Collar No Bark Collar Warning Beeper Bark Control E-CollarCategory: Big Dog CollarPET852 Bark Collar Product Description Upon your dog's first bark, this anti-bark collar will emit a short warning tone. If your dog barks again within 30 seconds, a louder warning tone will sound. Then if your dog barks again within another 30 seconds, a even louder warning tone will be issued along with a mild shock, the first and lowest level of correction. There are a total of 7 levels of correction that will be triggered by your dog's successive barks. Each successive bark will increase the correction level if the bark is within 30 seconds of the previous bark. If your dog does not bark for at least 30 seconds the collar will reset itself. As a built-in safety feature, if the correction reaches the seventh level, the collar will shut off automatically for approximately 1 minute. For level 1~2, only warning tones will be issued; for level 3~7, warning tones are issued first and static shocks will ensue. By pushing the button + button or - button, you can adjust the collar's sensitivity to your dog's bark and the environment in which your dog lives. Push + button to increase sensitivity and push - button to decrease sensitivity.
