Have you looked around and considered how many electronic devices you are using on a daily basis? Nearly every appliance or modern household item has electronics helping us and sometimes frustrating us, too. They have even made their way into the world of pet doors.

There are many manufacturers producing some of the best electronic dog doors ever to make your life and the life of your furry friends easier and safer. While smart dog doors offer the basic functionality of a pet door—to let your dog or cat outside and then back in again—their options and purpose vary greatly.

Like manual pet doors, electronic dog and cat doors can be installed in human doors, walls, sliding glass doors, and sash windows. Additionally, they can prevent unwanted animals from entering your home (a couple of models keep out raccoons), restrict which pets are allowed to use the door, feature timer controls, and can even raise the “flap” for the pet! And most of all, these types of pet doors can keep your pet feeling safe from any outside elements. Many will also not interfere with an electronic dog fence or have collars that can work with both. Let’s review some of the most popular models of these doors and their features.

The Best Electronic Pet Doors for Small Dogs & Cats - Raccoon Proof

For small doggies and cats, a couple of the most popular electronic door models are the SureFlap Microchip Pet Door and Cat Mate “Elite” 305 Super Selective Electronic Cat Door. These are two models that are raccoon-proof! They also use RFID technology instead of ultrasonic collar keys.

For larger dogs, the electronic doors that raise the flap for them, like the High Tech Power Pet Automatic Pet Door, is a great option. Both of these doors have a safe-close mode to prevent the door from closing on your pets. 

Another thing to consider when selecting this style of pet door is that the interior frame can be as high as 54 inches so you’ll need plenty of vertical wall or door space.

These are some of the most popular electronic pet doors in today’s marketplace. There are a few other doors for pets using simpler, magnet technology, but they don’t offer the technical options and clever solutions like the ones highlighted. As technological options expand there will be even more electronic pet door solutions in the future. Until then, you can view our current selection on our website! If you are deciding between manual and automatic options for your cat, take a look at our post about finding the right cat door for you and your pet!

Why should you choose an Electronic Pet door over Manual?

Pet doors are just like animals; they come in a variety of shapes, sizes, and colors. They are made for cats and dogs and they are made in both manual and electronic versions. These electronic options often restrict the full access of manual doors with the help of dog's collar keys. They do not often offer double flap options, but usually have locking mechanisms for any animals without a dog collar key.

You need to make an informed decision on getting a manual pet door or an electronic pet door. Learn the stark difference between each of them and decide on the best suitable manual or electronic pet door for you.

Manual Pet Doors vs Electronic Pet Doors

Manual pet doors are the most common option and have a broad selection to choose from. Manual pet doors allow for the same freedom as an electric dog door, but you cannot proactively manage what critters can use it. This could result in stray animals or other undesirables entering your home. A manual pet door is a great option for potty training, if you live in an area where wild animals or burglars are not much of a concern, or if you have a small pet and are looking for an inexpensive option to give your pet the freedom they deserve.

Electronic pet doors have all the benefits of their manual counterparts, but also add a level of security, as only your pet or pets are granted access. This is done through collar keys or implantable chips, which makes the door open once they are within a short-range. Flap doors are usually rigid plastic, making them more energy efficient in cold weather and less prone to chewing.

Electronic Pet Doors Provide More Security

Electronic pet doors have an extra measure of security because only recognized pets with collar keys or microchips will be able to use the pet door. These pet doors allow your pet to enter and leave your home while keeping out the strays looking to mark new territory, the wild animals looking for food, and any other unwelcome intruders. All of these doors have locking features where a physical plastic or metal piece holds the door closed, equivalent to a small deadbolt lock.

For large dog breeds, electronic pet doors can provide peace of mind that someone will not be able to come into the house via their pet door. The size of the pet door may also deter burglars because they would be wary of the size and type of dog behind the dog door.

Which Type of Electronic Cat or Dog Door is Right for Me?

If you have considered getting an electronic pet door for your pooch, here are some of the best doors that that you must check out:

Best Electronic Pet Door for Cats

SureFlap microchip pet door dog and kitty door

Microchip pet doors are perfect for cats who can’t keep a collar on. The pet door would be able to use the identification microchip of a pet to access the pet door. The most popular brand of microchip pet doors is SureFlap. Microchip doors use RFID technology to activate the automatic door.

Best Electronic Pet Door for Small Dogs

Small dogs are also able to use microchip pet doors. The best option for them would be the SureFlap Microchip Pet Door. Unfortunately, there are no microchip door options for medium or large breed dogs in the market.

Best Electronic Pet Door for Both Dogs & Cats

Collar key pet doors are great options for dogs and cats. They can be worn in addition to their existing collars. Most of the collar keys are resistant to the day to day activities of dogs, some are even waterproof!

Other Considerations:

When selecting your pet door, don’t forget to take into account your pet’s size. Not all pet doors are accessible for large breed dogs, and you don’t need a large door if you only have a small pet or cat. That’s why we have doors made for pets of every size!

Also, we never recommend installing an electronic pet door in a metal door, or close to any sort of metal material appliance, as metal can interfere with the electrical function of your pet door. The last thing you’d want is to cut a hole in an area of your house for your pet door and have it not work!

Pets: My best pal, my sidekick: Louie. We adopted him at 11 months old, he's almost 5 years old now. He loves life; all people, other dogs and even cats. You need to go somewhere, he's ready to accompany me which makes him the best travel companion I've ever had.
Fun stuff: I love hiking and wine tasting. For me, they're polar opposites. One takes me into nature and a peaceful state. The other is interacting with people and socializing.

  • The Sureflap connect is probably the best invention. So many people want the ability to connect to their smart device and this allows it. Hopefully in the future they will have a way for large dogs to use a door like this as well.

  • Nice and informative article. Will surely use these tips to keep my dog busy.

  • Hi,
    Thanks for the suggestion.
    That’s a brand new product offering from Sure Petcare the maker of SureFlap pet doors.

  • There’s also the SureFlap Microchip Pet Door Connect for Walls that has an app to control the door remotely! Check it out here:

  • Last year I had an invisible fence brand dog electronic door and fence installed for my 2 dogs. Fence works great and door did at first. When I first started using door I had it on unlock feature. After a few months I put in on auto lock and now my small dog will not use it. Even though I have it on the furthest distance it does not unlock until dog gets right up to it and it makes a loud noise which scares small dog. I had Invisible fence come back out and they tested another new door. They are telling me that I have a radio frequency interference problem, They tried all their frequency settings and and still does not open until right on it. It should open 4 to 5 ft. before dog gets there. Any suggestions?

  • Hello! I really like your blog! Continue to write more! Very interesting!

  • Hi Eline! We will send you a copy of the manual. Thanks!

    Rachel Lon
  • I bought a SureFlap microchip pet door, and somehow have misplaced the brochure that came with it.
    I need a copy of it that denotes what the various symbols in the control panel are & how to use, set.
    Though I have had other SureFlap doors, this panel is different & I cannot set it for the pet’s return.
    Thank You for your help.
