The 16 Best Dog Doors


A dog door is essential if you have a pet at home. It makes it possible for your pets to freely wander your home.

Remember, the ancestors of all animals, including humans, are wild animals. The freedom to run and jump outdoors is an instinctive need.

You can find several basic types of dog doors including electronic doors, sliding doors, door-mounted doors, and wall-mounted doors.

You might imagine that buying the best dog door couldn’t be easier. There are nevertheless some important aspects to focus on when you’re on the buying trail. Think about these elements and you’ll find that sourcing the best dog door is easier than you might imagine…

  • Materials: Dog doors and frames are made of different materials, although most are made from aluminum or plastic. Aluminum products will typically last longer.
  • Size: Do not buy a large dog door if you only have a small pet. You don’t want uninvited guests making their way inside. Several types of dog doors allow you to adjust the size of the entrance from inside. This is a great extra worth looking out for.
  • Installation: Some dog doors can be installed in minutes without any professional skills, while others have quite technical requirements. Pet doors with sliding doors are relatively quick and easy to install, and few tools (if any) are needed for the process.
  • Thermal insulation: The structure of a given door is critical if you live in an unfavorable climate. The air conditioner in your home will be forced to work overtime if your dog door is not properly insulated.
  • Security: A pet door provides an additional entrance to your home, so you should pay attention to security above all else. Be wary of strangers or other animals that could illegally enter your home. One solution to this is using electronic dog doors. These connect to your dog via a microchip on the neck and help you prevent uninvited guests from entering the house while also controlling your dog’s access.
  • Price: Price always plays a factor in any buying decision but it should never be the prevailing factor. Think about overall value rather than obsessing purely over the bottom line. After all, a cheap dog door is useless if it doesn’t last the distance.

Next, check out our 9 suggestions for the best dog door as we outline where each stands and falls.
Once we’re done with these dog door reviews, we’ll be answering the most frequently asked questions and showing you how to install dog doors the easy way.

Is a dog door on a wall better, or is a dog door mounted on a door better?

How should I choose the right size door for my dog?

Choose a dog door that’s large enough that your adult dog doesn’t have to lower its shoulders when passing. This is bad for the dog’s spine. Consider buying a pet door at least 2 inches wider than the widest part of your pet. Similarly, the opening height should be at least 2 inches higher than the length measured from the top of the shoulders to the chest of your dog, just behind the forelegs. Get this right or you could end up with an expensive and wasted hunk of plastic or aluminum.

III. 10 Steps to Installing Dog Doors


If you imagine that installing dog doors will give you an enormous headache, think again.

You’ll need some simple equipment and some basic DIY chops. That aside, you should have your dog doors installed in well under an hour.

Almost all dog door kits come with a template to help you with placement. Cut this out following the instructions provided. If your dog door kit does not come with a template, use the slide bundled instead and make your own template.

So, here’s what you need and what to do…

What You Need

  • Drill
  • Measuring tape
  • Jigsaw
  • Utility knife
  • Glass paper
  • Pet door kit
  • Caulk
  • Painter’s tape

What To Do

  1. Remove the hinge pins from your door using a screwdriver and hammer. Once you have taken these out, it’s time to remove the door completely. Position the door across a pair of saw horses. Make sure the interior side is uppermost.
  2. Most pet door kits come with a template bundled. When you’re establishing where to position your dog door, you need to think about the height of your pet’s shoulders. This will dictate placement. Once you’ve got this established, line up the template on the door. You should make certain the template is level. You also need to make sure the cutting line is 3 inches or more above the lower edge of the door. Tape the template into position.
  3. Drill a hole into each of the template’s corners using a 3/8-inch bit.
  4. With these corner holes drilled out, insert your jigsaw into one of these holes. Cut carefully along the template markings from corner to corner.
  5. Remove the waste material. Sand any rough edges. You can use a file if you don’t have a sander.
  6. Insert the frame into the hole to check for fit. Fine-tune if required.
  7. Mark out holes for your mounting hardware. You now need to remove the interior frame. Drill holes using the bit sizes recommended by the manufacturer. You should find this in the instruction manual. Ensure you drill the holes precisely perpendicular so the hardware and frame line up neatly on both sides.
  8. Once you’ve drilled your holes, it’s time to pop the interior frame back in again. Ease this into position from underneath the door. At this stage, you might need to trim the core frames for a snug fit. Install the fasteners as you hold the pieces of the frame together. Trim off any excess lengths of fastener.
  9. Use caulking around the outside of the frame. This imparts a weatherproof sealant.
  10. You can now rehang your door. There should be a slide with the kit that you can use to keep your pet inside. You should always check your pet is indoors before putting the slide in place.

Note: You should check carefully with all local building codes and also with your insurance policy before you install dog doors. In some cases, you might need fire-rated exterior doors. It always pays to do your due diligence before committing to purchase.
