Review on ChunHee Dog Doorbell: Waterproof Dog Door Bells for Potty Training & Clear Communication by Monique Franco

I bought these for my Great Dane and like magic it only took me a few days to teach her how to use them. They are very easy to install and just as easy to train your pet. Touch is very sensitive, so it's MUCH easier for your dog to learn the process. You simply approach one of the three touch buttons and touch it with your nose. Our dog will bite the button and its tongue, nose, mouth or whatever is touching it. Rschunimagu. It's VERY durable, like I said, she bites into it to tell us and barely scratches it. The adhesive pads are very durable. I even tried just prying the button off the wall to see if I could, but to no avail. We have a button on each exit door, although you can put one on the outside for entry. All signals reach the receiver in our kitchen. It has multiple ringtone options and it is very easy to change and adjust the volume. The only problem is that your dog can constantly call to chase the squirrel like our dog does. Rschunimagu.
