PATPET Outdoor Remote Dog Training Collar, 600M No-doggy's perfect, but the PATPET Outdoor Remote Dog Training Collar is a great solution to your beloved pooch's problem behaviors. It lets you send her a safe, but unmistakable message when she's doing something that's not okay. A user-friendly remote control allows you to choose between irritating beeps, vibrations or mild electric shocks at various levels of intensity—and warns you when the stimulation may be getting a little too intense for your furry friend. Both the control unit and the collar are powered by two-hour rapid-charging lithium polymer batteries and have a 600-meter range.
