Why not enrich your dog’s life by giving it controlled access to the outdoors? Spending long hours alone at home is just as boring for your pet as it is for you. But what’s the best smart dog door you can get?

From reviews to a complete guide, we’ll explain everything you need to know about electronic dog doors. Let’s dive right in!

Evaluation Criteria — Reviewing Smart Dog Doors 

Searching for the optimal smart dog door can get a bit overwhelming. To ease your choice, we followed a specific research approach. 

Quality and Durability — Materials

Spending money on what turns out to be a low-quality product is quite a bummer, so it’s crucial to do your research. Many dog doors come with waterproof collar keys and batteries that last from 3 to 12 months. Some offer excellent insulation, bulletproof flap, rust-proof hardware, and aluminum panels.


We aimed to find a good remote control dog door for every pet size. But many products are specifically made for small pets. Still, we found some that will fit even the largest dog breeds. 


Who doesn’t want to purchase a product and install it in the easiest way possible? Unfortunately, many companies don’t help with that. But most products come with instructions for better and quicker installation. Some offer a DVD guide, too.

Additional Features

The best smart dog gates offer special features like an automatic opening and closing. Some lock immediately when the sensor no longer detects the smart key. Others use an app that controls the dogs’ movements. Safety features, such as reopening the door in case of obstruction notice, could also be helpful. 

Warranty & Customer Support

Product guarantee? Yes, please! While many dog doors don’t come with a warranty offer, some companies guarantee replacements in case of malfunctions. Generally, the warranty varies from one to three years, with a 30-day return policy. Most brands also offer customer support available 24/7.


We dug deep into product reviews and read customers’ questions and opinions. Their impressions and honest feedback helped make our electronic dog door review as reliable as possible.

A Guide Towards the Finest Electronic Pet Door

Do you want your pet to have a fancy gateway in the house? We’ll tell you what to look for. Let’s dive right in. 

How to Pick the Right One?

There are many things to consider before buying an electronic door for your pooch — and here, we cover them all. Take notes and let’s check out the top five factors.

Dog Size 

The ideal dog door is about two inches higher and wider than your dog. Luckily, size options range from the smallest to the biggest. Just remember to measure your dog’s height and width before buying.

Number of Pets 

If you live with several pets, they should all pass through the door with an installed dog door. So consider the size of your biggest pet before picking one. Some have huge memory storage and offer more than one collar key.

Place of Installment 

You can adjust dog doors on walls, doors, or sliding glass doors. Entry doors and patio glass doors are the easier options. In contrast, wall doors require a bit of handy work, especially if it’s concrete. 

Features to Consider 

Unique features sound great, but do you and your dog need them? Think about that before buying a door for your furball. 


With smart dog doors, you’re in control. You can adjust the mode with one click. Consider a dog door with a timer or app-linked smart door that observes your puppy’s movements. 

Flap Style 

There are two flap styles on the market — automatic and manual. If your dog likes to open the door with its head, then a manual one would do the job. But there are excellent automatic sensor doors that open by detecting your pet’s collar key or microchip. 


Most sensors respond to ultrasonic MS-4 keys, RFID tags, or microchips. If your dog isn’t microchipped, go for the first two options. The sensors work by detecting the collars from a given distance range, mostly up to 10 ft. 

Power Source 

When picking the optimal smart dog door, you can choose between a battery or an electrical power source. If you have a plug-in nearby, an electrical door will save you money on batteries every few months. 

Energy Efficiency 

Apart from providing excellent security, the doors need to be energy efficient, as well. Search for those that insulate and keep cold and warm temperatures out. We recommend doors that resist wind, rain, and snow, with flaps that protect from UV rays and hot temperatures.


There are two types of door designs — metal and plastic. With smaller dogs, the plastic one fits just fine. But if you have a bigger pup with destructive tendencies, consider getting a door with an aluminum dog door built-in. 


Some companies promise the highest quality products for a price. But you may find cheaper products of excellent durability, efficiency, and quality. If you’re lucky, you may find a few on sale, too.

Understanding Smart Dog Doors — What Are They and How Do They Work? 

A smart dog door is a high-tech, safer model of a regular pet door. The technology gets your pet in and out, triggered by a collar microchip or a unique tag. 

Most of these products are battery-powered or tap directly into the wall. The ideal smart dog door has settings like automatic locking/opening, timers, and security features that allow only your pets to pass. Despite our technological advancements, WiFi dog doors remain uncommon.

Types of Electronic Dog Doors 

We divided dog doors by sensor, flap, and place of installment. Let’s check the differences. 

Sensor Type

Radio-Frequency Identification (RFID) — It’s an automatic dog door, synched with RFID collar tags, that responds and communicates via radio waves. The sensors can detect the tags up to 10 ft. 

Microchip Sensor — These sensors activate through your pet’s embedded microchip. They usually have massive memory storage and automatically lock when they detect non-microchipped animals. 

Magnetic — Dog doors that run on multi-magnets and don’t need batteries. Magnetic collar keys are a bit thicker and heavier than standard door collar keys. 

Ultrasonic Waves — This high-tech pet door usually runs on a battery or electricity. The door is opened with an ultrasonic collar key with a battery similar to those in a watch.

Flap Type

Single/Double flap — A single flap door has one flap, generally on the inside. In contrast, a double flap door has a flap on the interior and the exterior.

Plastic, Vinyl, or Aluminum — Plastic dog doors are typically built on a plastic frame of PVC (Poly Vinyl Chloride). Vinyl sliding doors are from a plastic-based material that’s sturdy and lightweight. This automatic dog door doesn’t conduct heat as well as the aluminum. The frames and tracks on vinyl sliding doors are heavier and longer than on aluminum sliding doors. 

Installment Place 

Door — These doors allow your pet to come and go through the same door you use. They insulate the room and protect the entry from dirt, water, or snow. 

Wall — A wall dog door is a perfect choice for versatility. But it’s difficult to install and might be a problem if you’re not a handyman.

Sliding Glass Door — Sliding glass doors might be the optimal exterior doors with pet doors because they’re the easiest to install. You only have to attack these pre-made dog doors to your patio door.

Benefits of Electronic Dog Doors 

Electronic pet doors are the future. But what are their benefits? Read more to find out. 

Your Dog Will Have More Independence

These doors give your pet unrestricted access to bathroom breaks. When your dog has the freedom to do its business wherever it wishes, that can prevent many health problems and spare your precious floors from an accidental mess. Just make sure your pet also has a GPS dog collar so you can always know where it is.

More Play Time, Less Door Scratching

Dogs, like humans, need the freedom to explore the outdoors. And we all know how destructive they can get if they’re bored. The top smart pet door will grant them much-needed adventure. The best part is that your furniture will be spared.

Secure House for Peace of Mind  

Smart doors allow your pets to enter and exit the house without help but on your terms. In contrast to ordinary pet doors, the smart ones receive signals from collars or microchips, so the only one that can get in is your furry pal. Most importantly, the automatic locking feature will keep intruders out.

If you want your dog to run free in the backyard but worry about your pet getting out, a wireless fence for dogs is the way to go. These fences alert the dog when it’s too close to the fence, causing it to turn back.
