Unlike most smart objects, which can connect to the internet, the automatic doors are simply secure versions of standard dog doors and they are more high-tech.

A lot of products also offer automatic locking system, and you can lock it if you want to keep your dog inside.

Features to consider when choosing an automatic dog door

Smart Access – Microchip, RFID

How an automatic can work well based on the smart access features of those doors, which are based on microchip, or radio frequency identification. A microchip is installed between his shoulder blades of dogs that refuse to wear a collar. The microchip’s sensor will detect the dog and then open the flap panel. Radio frequency will work on radio waves and is usually set automatically.



The smart doors come in different sizes for different types of dogs, from small to large, or even extra-large. Big pets can use large or extra-large doors, while little ones need small-sized panels.


The dog’s height is the most important, so that accurate pieces can be cut from the door. Then holds are drilled inside the frame, and panel flap will get installed in the cutout. Do note to purchase a pet door which is big enough for your furry friend to pass through.

Smart App to connect with

Some of wifi pet doors have a smartphone app connecting the dog door with the app on your phone. By that way, you can control the workings of your automatic door using these apps anywhere. Also, they have a variety of features, and dog owners are able to monitor their dog’s activities and habits.
