Ding-dong. Oh, that's my dog ringing to come in.

And now it's time for a visit to Dick’s Gadget Warehouse

It was about 12 years ago when I showed the Happy Paw Doggie Doorbell on Good Morning America. The company that made it figured (and quite correctly it turns out) that dogs and cats could be taught to press a button to let you know when they want to go out or come inside. Under the button was a wireless transmitter, which activated a wireless receiver. The receiver could be set to sound a chime, or an electronic bark. Although I can’t find the company Happy Paw anywhere, or the version of the Doggie Doorbell that I have, there are plenty of similar products for sale. One of them has the wireless sender designed to look like a big paw print. And while the one I have was designed to put on a door at the place where your pet would normally scratch to come in, or go out, the newer version can sit on the floor or mount on the wall. The receiver works up to 100' away from the transmitter and plugs into an AC outlet. The transmitter requires a single 9-volt battery. The newer one lets you buy additional transmitters so your pet can let you know if they want to go out, or come in.
