Review on Opibtu Dog Door Bell: Wireless Potty Training System with Waterproof Touch Button Bells (1 Receiver & 2 Transmitters) by Chelsea Hunter

Five month old puppy learns in one (1) ONE day! Love it. We really needed to harden it for outdoor time, not outdoor play. By day eight, she seems to understand the difference. In the near future we will no longer have pee pads. Hooray! I like that there are two buttons. We'll use another one to train her when she wants to come back. What I like best is the lighting function, as it works like a motion sensor, illuminating the hallway with ambient light when there is movement. It also works with a beep when activated. Excellent price. Excellent purchase. Update for 2 months: everything works. The dog makes good use of it. We haven't fully convinced her that she is strictly for potty training and not for outdoor play. 😆 well, more exercise for us. We noticed that she uses her nose for serious cues and her paw to fool us. She leans on him when it's urgent. These wind chimes are a must have, so you can't go wrong with what you need.
