Dog doors come in handy in many situations. Many dog owners are at work during the day while their dogs are left inside. What’s more, dog owners are often awakened to the sound of a whining dog needing to go potty, leaving them no choice but to get up and let the dog out. Considering these situations, electronic dog doors are extremely valuable. No more calling a friend or neighbor to let your dog out if you’re running late getting home, as your electronic dog door will let your dog out for you.

Electronic dog doors come in different sizes, but they all work similarly to one another. Most work by using Radio Frequency Identification Devices (RFID)1 that are lightweight and attach to your dog’s collar. Intrigued? If so, keep reading, as we’ve selected five of the best electronic dog doors available based on consumer reviews. Pull up a chair, and let’s check them out.

Buyer’s Guide: Choosing the Best Electronic Dog Door

Hold on to your hats because we’re not done yet. At first, trying to choose the right electronic dog door for your needs may seem overwhelming. Still, to ease the process, we’ve included a buyer’s guide to help you understand what to look for before committing, especially considering the installation process, price, and your specific needs.


Knowing what size you need is an important factor. Your dog should be able to come and go through the door without any trouble or, worse, without getting stuck. You’ll need to measure your dog from the ground to the top of his shoulders and then add 2 to 3 inches (your dog’s shoulders should not touch the sides of the dog door).

If you have more than one dog, measure your largest dog and go by that measurement. It’s OK if your dog has to crouch a tiny bit or lower his head a bit to get through, but you don’t want your dog crouching to where the stomach hits the frame.

Sensor System

Most electronic dog doors work by some sort of sensor system that is programmed to your dog’s microchip or ultrasonic collar (these collars are included with your dog door). It’s best to find one that sensors a directional path, meaning the door only opens when your dog walks toward the door rather than near it. Otherwise, the door can open and close when not needed.

It’s also wise to look for a dog door that automatically stops if there is an obstruction to keep your dog from getting injured.

A quality feature of electronic doors is that most have a security feature complete with a deadbolt lock while not in use. This feature keeps intruders and stray animals away, and the door will only open for your dog or other dogs the system is programmed to. Ensure the door is durable with quality material and not something that someone can break easily.


Some systems allow you to program the door to your dog’s microchip, and some work with Smartkey collars or Radio Frequency Identification Devices (RFID) that go onto your dog’s collar. These collars are needed if your dog has no microchip.


Installation can be tricky, but they all come with instructions. Something to remember here is you’ll need to cut into your wall or door for installation, which makes choosing the correct size very important. You can also opt for a wall tunnel that allows you to install the dog door on an exterior wall.  If you’re not sure you’re comfortable installing the dog door yourself, enlist a friend or someone with the knowledge of how to do it correctly.


You’ll want a dog door with an airtight seal to keep inclement weather outside where it belongs. You certainly don’t want a draft through the door, which can drive up your energy costs.

Vertical or Swing Door

You can choose a dog door that opens vertically or swings open with a flap. If you opt for a vertical door, ensure the mechanism that opens the door is quiet. Vertical doors are easier for your dog because they don’t need to push the flap open. Vertical doors are also an excellent option for senior dogs or dogs with mobility issues. However, flaps work just fine too.

Programming Options

Some electronic dog doors have the option to program and customize for in-only, out-only, full access, or closed and locked. This allows you to determine when your dog can have access to the door and when he can’t.

For example, the in-only feature only allows your dog to come inside but not go back outside. The out-only allows your dog to go out but not back in. This is a good option if you have visitors and don’t want your dog around at the time. However, you can choose full access or closed and locked, which is an excellent feature at nighttime when you don’t want your dog outside.



We hope our reviews of the best electronic dog doors help you in making the best decision possible for your needs. For the best overall electronic dog door, the High Tech Pet Products PX-1 Power Pet Fully Automatic Pet Door has an airtight seal, vertical door, and deadbolt for the best overall. For the best value, the PetSafe Electronic SmartDoor has an insulated flap that seals when closing, the capability to program up to five collars, and is reasonably priced.
