Dog Door for Extra Large Dogs, The Good & The Bad

dog is thinking how to get into the house through a dog door

You love your dog and he is your best fur-iend. But sometimes you get tired of getting up to let him in or out 10 times a day. Maybe you should get a dog door so he can go in and out as he pleases so you can both get some relief. 

Dog doors have come a long way since those simple little holes in the door. Now they have doors that lock, some that have insulation to keep the elements out, and even some that are electronic. And yes, they do make them big enough for your extra large fur buddy. Here are the advantages and disadvantages you need to know first. 


Convenient: The first positive thing about doggie doors is the convenience. They are good for both you and your pooch. This way, they have the freedom to go in and out as needed and you can continue what you are doing without interruption. Your pup can go out and enjoy the yard while you enjoy dinner and a movie or a good book. 

Great for busy families: Having a dog means living your life around his schedule because you do not want him going potty on your floor but you do not want him to have to hold it all day until you get home. Rather than rushing home from work to let your dog out, you can relax and hang out with your friends after work. 

Emergency door: All pooch parents worry about what will happen to their dog in an emergency such as a fire. How will he get out if you are not home? You could hire a neighbor to be his emergency escape. But what if your neighbor is not home either? Having a dog door means he can escape if he needs to so you do not have to worry every time you leave the house. 

Stress relief: Another benefit of having a dog door is that your dog will feel more at ease knowing he can come and go as he wants. This means they will be less likely to pick up bad habits when they are bored like chewing or barking. Instead, he can go out and play.


The dangers of the outdoors: Even if you have a securely fenced yard, the outdoors can be dangerous for an unsupervised dog. He may dig a hole to get under the fence or get into a fight with a local squirrel and get hurt. Take a walk around the yard every day and check for dangers like toxic plants, loose wires, or escape routes that your pooch has been working on.

The weather: You definitely will have some energy concerns with an extra large dog door. Even those that brag about being energy efficient may not be good enough to keep out the deep cold in some parts of the world. 

Unwanted visitors: Obviously, if your fur baby can get in and out of your house, so can the neighborhood cat, possums, raccoons, and other creepy critters. While you can lock the door at night to keep the wildlife at bay, an electronic dog door is the only thing that can assure you that unwanted visitors will be kept outside where they need to be.

Safety issues: Having an extra large dog means you need an extra large door. That gives thieves the opportunity to enter your home as well. Make sure your dog door opens to the backyard and that the backyard is secure from prying eyes. If they do not know it is there, they cannot be tempted to use it the next time you are at work.

Difficult installation: Some of the dog doors on the market require a Ph.D. in DIY and that may be what is stopping you from getting one. You may have to hire someone to install it for you. But some doors are pretty easy. Especially those that fit into a sliding glass door. These are easy peasy. 

Types of Dog Doors

There are several kinds of extra large dog doors on the market and it may lead to a bit of confusion trying to figure out which one to get for your fur buddy. There is no easy answer because every dog and every house is different so you have to get the one that is best for your dog and home. 

These choices include the regular dog door that has been around for ages, the dog door for sliding glass and patio doors, dog doors for screened in porches, and then there are the dog doors that you can install into your wall instead of a door. We go into more detail below to help you understand the pros and cons of each. 

Regular Dog Door

The regular or standard dog door is made to fit exterior doors, but there are slso some that are made for interior doors as well. You do not want to use an interior dog door on an exterior door. This type of dog door is typically made of a plastic or metal frame with a vinyl door flap. Some of them also have a panel to “lock” the door when needed, such as at nighttime. 

Dog Door for Deck or Sliding Doors 

For those who have a sliding glass or deck door, installing a dog door can be a breeze. These typically require no cutting at all because all you do is insert it into the space between the door and the wall with the door partially open. These dog doors usually have a flexible flap like the regular dog door and some also have the locking panel as well. 

Dog Door for Screen Doors and Porches

Screen doors and porches are sometimes challenging because you want to find one that will be able to fit into the screened-in style while still being rigid enough to hold up to your extra large fur baby. The easiest and most efficient are those that have a saloon style door that lets your pup go in and out easily. These usually have magnets to keep the door shut after he passes through.  

Dog Door for Walls

If your door does not lead to your backyard or whatever space you want your pooch to go, you may need to install a dog door in the wall. This sounds more ominous than it is. Most people hear “hole in your house” and get freaked out. While these can be more difficult to install they are often more efficient than the traditional dog door. 

6 Rules Of Thumb When Buying an Extra Large Dog Door

a large breed is looking out of through the front door

When you are ready to shop for your new extra large dog door, there are 6 important considerations you need to think about. For example, you need to measure your dog so you know what size door you need. Also check the security and locking mechanism, durability and materials, insulation and weatherproofing, setup difficulty, and warranty.

  • Measuring for a Large Dog Door Size: One easy way to measure the width your dog needs is to open your door just enough to let him through and measure that space. Add 2 to 3 inches and that is how wide it should be. For the height, measure your pup from the floor to the spot where your fur buddy’s head and neck meet right above his shoulders.
  • Locking Mechanism & Security: There are going to be times that you want to stop your pup from going through the door and most dog doors have a locking panel. Many of the budget doors do not have these or if they do, they are inadequate. However, this is not a good feature to be cutting costs on.

    The safety of your dog as well as yourself and your family are the most important things so you want to make sure the dog door you get has sufficient security features. For instance, having an extra large dog door can be an invitation to criminals and a wide array of stray animals and wildlife. Make sure the only one using that door is your fur baby.
  • Materials & Durability: You will notice right away that extra large dog doors are made of all sorts of materials. Some of these may include plastic, vinyl, metal, aluminum, and even glass. “Chews” the one that is easiest for your dog to use and will last for years.
  • Insulation & Weather Proof: If you live in an area where it gets extremely cold or hot, energy efficiency is going to play a factor too. After all, you can go through and insulate your house but if you have a dog door leaking all that unwanted air in, that insulation is not going to be as efficient. Find one that has insulation and several flaps for protection from the elements.
  • Easy Setup: It is best to get an adjustable frame dog door for easy setup that fits to your space. Look for those that say they have a “telescoping” frame because they work with all thicknesses and insulation. Read the installation instructions before buying for best results.
  • Warranty: The warranty is important with extra large dog doors because most of them are pretty expensive. Find the one with a long warranty period like months or years instead of days. If the manufacturer believes in its product, the warranty should be longer than the typical 30 days.

Common Questions From Dog Parent

How big is an extra large doggie door?

The biggest extra large dog door on our list is the Ideal Pet Products Designer Series Ruff-Weather Pet Door. At 16 inches wide and 20 inches tall, pretty much any pooch can fit through this one. However, the Hale Dog Door has a much higher opening at 27.5 inches if you have a really tall fur baby. 

Can a person fit through a large dog door?

While it is certainly possible for a human to fit through an extra large dog door, there are many things you can do to prevent this from happening in your home. For example, look for safety features like a steel locking panel or using a microchipped collar that only allows your pup in and out. But make sure the opening is secure from humans who may be able to figure it out.

How big does a dog door need to be?

Fur-st of all, you need to measure the height of your fur baby. Have him stand up straight and measure him between the shoulder blades right below the neck. Add 1 or 2 inches to that just to be on the safe side and that will be your height. Also, make sure the step-over is no more than ⅓ of your pup’s height. 

Measuring the width is easy too. Open a door just enough to let your dog pass through it. Then measure that space and that should be the right width. Although you can add an inch in case your fur baby gains a few pounds. To make sure he fits, try making a door with those measurements in a cardboard box and see how easily he can go in and out.
