Hopeseily Wireless Doorbell, Dog Bells for Potty Training IP55 Waterproof Touch Doorbell with 55 Melodies 5 Volume Levels LED Flash-2 Receiver, 1 Transmitter-

A wireless dog bell is an ideal unit for easily installing a doorbell without the hassle of wiring. Simply plug the receiver to an AC outlet and mount the transmitter where needed and you are ready to go! The "transmitters" can also be placed on the floor for easy use with a paw and no damage to the wall. In fact, we didn't even attach it to the floor, just attached it to a small board so it's just laying there by the door and we could put it away when we weren't training her and could place it where we liked and now the dog uses it that way. FEATURES Modern&stylish design Easy installation Approx 500ft operation range (open air) 5 Levels of VOLUME IP55 Waterproof 55 Ringtones Low power consumption Tips for Training Do your training during feeding time. Put the food outside the door, then show the dog how to ring the bell. When they do it, praise them and immediately open the door. Put your dog out any time they ring the bell, whether they want to or not! A puppy would ring it and when I'd come over to let him out, maybe he didn't want to go out, just wanted to play. So put them out anyway! If you're consistent about it, they will only ring when they want to go out.
