The Best Dog Doors

Let the dog out, let the dog in. Let the dog out, let the dog in. Perhaps you are familiar with this song and dance when it comes to your pooch. We know dog owners can spend a good chunk of their time just opening and closing a door for their furry loved one. And if it were up to your dog, he would go out and come in more often than your phone alerting you to social media notifications. Enter the dog door. A dog door can give your dog the freedom to come and go, freeing up your time from the constant in-and-out game.

We reviewed dozens of dog doors to identify the best ones out there. We considered size, durability, usability, safety, structure, and price when compiling our list. We looked at the standard door-access models, wall-mount dog doors, sliding glass panel doors, and weatherproof pet doors.

Who Should Buy a Dog Door

A dog door is not for everyone, nor is it right for every dog. So how do you know if you should have one? A dog door is a great option for those who have secured, fenced-in yards, and want their dog to have the freedom to come and go. Maybe you have an active dog and you spend far too much time letting her in and out all day. With a dog door, your furry friend can take herself outside and run around the yard to burn off energy. It can also be very helpful for people who work long hours and don’t want their pooch cooped up all day. But a dog door doesn’t have to be for outdoor-use only.

Dog doors are convenient for indoor-use as well. They can be installed in walls or doors to create new pathways inside your home. Put a dog door in the door that leads to the garage to give your dog an alternative option for outside. Or add one on to your sliding glass door, which is a great option for those who rent. Another reason to have a dog door is to allow your dog access to a room that needs to be closed-off, whether for privacy or temperature control.

Important Features to Consider

A dog door should have a few important features. Here’s what to consider when selecting a dog door.

  • Size. It is essential to measure your dog before purchasing a dog door. You want to be sure your dog can fit comfortably through the opening before cutting a hole in your wall or door. Typically, the top of the door should be 1-inch higher than the height of your dog’s shoulders, and the width of the door should be 2 inches more than the widest part of your dog. Always check with the manufacturer’s suggested measurement chart before choosing the size of your new dog door.
  • Safety. Keep in mind who will have access to the dog door – such as unwanted intruders, young children, stray cats, or other pets – in relation to where the door is located. You don’t want to put a dog door that leads to an area that may cause an accident, like an in-ground pool, stairway, or busy street. A dog door that goes to the outside should come with a security panel to close off access when necessary, and you might want to equip your dog with a GPS tracker to ensure you can find him quickly if he ventures past his safe zone. For dog doors that are placed inside, this may not be a priority feature.
  • Type. There are all sorts of dog doors to choose from: standard, wall-mount, sliding glass, window-sash, and weatherproof, to name a few. You will need to determine where you want to put your dog door, and what kind is best suited for you and your dog.
  • Installation. Most dog doors necessitate a hole in your door or wall in order to be installed. This could be easy or hard depending on your handyman skills. Many of the dog doors we reviewed provide easy-to-follow instructions for an equally easy installation. Though some basic tools are called for, the hardware required to finish the job is included with the dog door. Do not cut into a wall if you think there may be electrical wires or plumbing. Consult a professional.
  • Training. Dogs may not instinctually know to walk through a dog door and may need a little help navigating the vinyl flap. It shouldn’t take much training to get your dog to go through the door, but be patient while they learn. Leaving the flap off for a short time could help until your dog is more comfortable with walking through the hole. Positive rewards, such as praise or treats, are also good ways to teach your dog to use the new door.

Frequently Asked Questions

What is a dog door and how does it work?

A standard dog door is a structured frame made out of plastic, aluminum, or other solid material, with a flexible or hard flap hanging in the center. It is designed to be slightly larger than your dog and installed in various locations, such as a door, wall, or window, to allow your dog access to an area that might otherwise be closed off.

Most dog doors can be thought of as open windows fashioned with a heavy curtain. They allow movement to another area, be it outside or another room in the house. When your dog walks through it, the flap moves like a curtain so it flows over your dog. When your dog exits out the other side, the flap closes shut, often held in place with magnets. Typically, a solid panel is included, which is used to shut the dog door completely.

How do you install a dog door?

When you purchase a dog door, it will come with instructions on how to install it. Generally, you will need to cut a hole in your door or wall. Many of the doors come with a cutting template that you’ll follow. Basic tools are required, as is some basic knowledge of carpentry. If you are at all unsure, you may need to contact a carpenter.

Are dog doors safe?

Dog doors can be safe when chosen and installed correctly. A dog door that is not the right size for your dog or is installed improperly could harm him. Likewise, a door that is not placed in the right location could cause problems. Many dog doors come with a security panel for closing the door to unwanted intruders.

How much does it cost to install a dog door?

If you have the basic tools and knowledge required for installing a dog door, installation shouldn’t cost anything above the price of the door. However, if you find you need a professional to install it for you, it could cost you anywhere from a few dollars to hundreds of dollars, depending on who you hire.
