Remington Silent Dog Whistle

Almost inaudible to the human ear, the Remington silent dog whistle features an adjustable pitch that can be heard by your dog over 300 yards away. To adjust the tone of the whistle, remove the hard plastic sheath and turn the adjustment to the desired setting. To achieve maximum results, always use the same frequency pitch while training. When used consistently and in conjuction with positive reinforcement, desired results can be seen within days.
