Best Overall: PetSafe Freedom Aluminum Pet Door for Dogs
For a simple, classic door door that works for most homes and most dogs, we’re fans of the PetSafe Freedom Aluminum Dog and Cat Door (all of these picks will also work for homes with indoor-outdoor cats). This door features a solid aluminum frame and a flexible, tinted flap that’s easy for your pet to push through. It can be secured with a slide-in panel when you want to close it off (like when you're not at home or you're in bed), and it’s strong enough to prevent any animals outside from trying to paw their way in. The door is easy to install, with an included template, detailed instructions, and all the necessary hardware.
The PetSafe Freedom Aluminum Dog and Cat Door comes in sizes running from small to x-large, and most customers give it their highest recommendation. Installation is fairly straightforward, it has an unobtrusive look, and—most importantly—it works well and makes managing your dog’s bathroom breaks much easier.

Best for Sliding Glass: PetSafe Freedom Aluminum Patio Panel Sliding Glass Pet Door for Dogs and Cats
While most dog doors are intended to be built into a standard wooden door, there are plenty of options for people who would rather avoid cutting into an existing part of their home. The PetSafe Freedom Aluminum Patio Panel Sliding Glass Pet Door is perfect for renters or anyone who’d prefer a dog door that’s detachable and non-permanent. This insert fits into most sliding glass door tracks and is made of weather-resistant aluminum and shatter-resistant glass. It has a magnetic closure and slide-in closing panel when you want to shut off access to your home through the dog door. The panel itself comes in two different heights, and the lower dog door component is available in four different sizes (don’t worry—they’re sold together as a single unit).
Customers say they wish they’d bought the PetSafe Freedom Aluminum Patio Panel Sliding Glass Pet Door years ago. It’s incredibly easy to install and typically fits well, and the fact that it doesn’t require any invasive cutting or other forms of installation makes it a real winner for renters. Just bear in mind that it’s not insulated, so if you experience cold winters you might see an increase in energy use.

Best Large: Super Large Thru-the-Wall Ruff Weather Dog and Pet Door
Think dog doors are only for small breeds? Think again. The Super Large Thru-the-Wall Ruff Weather Dog and Pet Door measures 15 x 23 inches, making it tall enough to accommodate most larger dog breeds. It has a dual-flap door for increased energy efficiency, and an ultra-durable design to hold up to the harshest elements (not to mention your dog’s size). This type of dog door is intended to be installed in a wall, not a door, and includes a kit and step-by-step instructions to get you going. Each flap stays closed with a magnetic strip at the bottom, which creates an “air pocket” in the door’s interior tunnel section to help control your energy bills.
Customers write that the Super Large Thru-the-Wall Ruff Weather Dog and Pet Door works beautifully for their large breed dogs, with some noting that their 160-pound pets use it with no trouble. While the install can be a little trickier than some other options, it’s worth it for the low-profile design and added freedom for your dog.

Best Electronic: PX-2 Power Pet Fully Automatic Pet Door
For a high-tech spin on the old dog door, we love the PX-2 Power Pet Fully Automatic Pet Door. This electronic dog door connects to a sensor in an included transmitter collar, opening automatically when your pet comes near—no pushing required. Just as importantly, you can feel secure the door will remain shut when any unwelcome visitors come poking around. It’s great for hesitant pets who don’t love the idea of nudging their way through a flap, and is airtight, windproof, and weather-proof. The door even includes custom settings, allowing you to select in-only, out-only, full-access, or closed-and-locked options.
The PX-2 Power Pet Fully Automatic Pet Door fits pets weighing up to 100 pounds (the opening measures 41 x 16). Buyers say that their dogs took to it right away and that installation was fairly simple (although some used a professional). It’s highly secure, and the transmitter can be reattached to your collar of choice if you don’t like the one included.Continue to 5 of 8 below.

Best Insulated: Perfect Pet All Weather Series Insulated Pet Door
If dog doors have one major drawback, it’s that they can take a noticeable toll on your energy bill. Fortunately, an insulated door like the Perfect Pet All Weather Series Insulated Pet Door can go a long way toward correcting that issue. This door uses a double vinyl flap to create a pocket of air in the middle part of the door (it goes inside your wall), cutting down on your energy waste as your dog goes in and out. The door comes in sizes ranging from small to x-large.
Buyers say the Perfect Pet All Weather Series Insulated Pet Door is a great product, easy to install and well-designed. The company gets high marks for its great customer service as well, which can come in handy if you get stuck during the installation process (bear in mind that the wall installation kit is sold separately). Others note that this door not only keeps the weather out, but does a great job of blocking out noises that other dog doors might allow to seep inside.

Best Microchip: SureFlap Microchip Pet Door
Looking for an electronic dog door, but don’t want to deal with putting a sensor on your dog’s collar (which might get knocked off during play)? The SureFlap Microchip Pet Door opens and closes in the presence of one item your dog will never lose—the microchip already implanted beneath their skin. The door works with 9 (Avid Secure), 10 (FDXA), and 15 (FDXB) digit microchip numbers (ask your veterinarian if you’re not sure which your dog has). The door can be programmed to open for up to 32 different chips and can be programmed with a single button-push. Don’t have a chip? A sensor collar can be purchased separately.
Note that, unlike other automatic doors, this door only restricts which pets can enter your home, but won't restrict pets from exiting. That means this door is not ideal for houses where some pets (like indoor cats) cannot be let outside without supervision.
The SureFlap Microchip Pet Door measures approximately 11 x 10 inches, so it’s best for small dogs. Programming is very straightforward—just set the door to “learn” mode, and it’ll capture your dog’s chip the first they walk through it.

Best Wall-Mounted: Endura Flap Double Flap Wall Mount Pet Door
Whether you don’t have a door that works well with a pet door or you simple need the option to put your doggy door wherever you want, a wall mounted door offers more freedom than one installed into a door. The Endura Flap Double Flap Wall Mount Pet Door is an energy-efficient, double flap dog door that mounts into an exterior wall so Fido can come and go as he pleases. It features a three-sided power magnet to ensure it stays shut even in high winds and includes a clip-locking cover to guarantee it stays secure when you’re away. It works for walls up to 8 inches thick and the heavy gauge metal material won’t flex or warp against the wall.
The Endura pet door comes in small through x-large, with the medium size measuring 8 x 15 inches. Reviewers say it works well, even in harsh weather conditions and say it’s easy to train dogs how to use it.

Best Airtight: High Tech Pet Products Armor Flex Airtight Pet Door
