Dog Door DIY

Got a pooch that loves to go in and out all day long for absolutely no reason? A dog door may be just the ticket to keeping you sane and keeping your dog satisfied!

When safely used, dog doors open up a world of sniffs and adventures within your own backyard for your pooch – they help keep him occupied without relying on your constant attention. 

When it comes to picking out the right dog door, though, one size does not fit all.

The commercially made doors on the market are of varying quality, but even the very best dog doors available may not suit the needs of your furry friend or your home. 

DIY dog doors allow you to construct the canine entryway of your dreams, from sizing to safety, and everything in between. Unique plans offer ample opportunity to customize your dog door based on your materials, budget, and, most importantly, the size and shape of your dog. 

Below, we’ll cover the basics of dog doors, and then we’ll share some of our favorite DIY dog door plans so you can match the right hatch to your home!


Why Should You Make Your Own DIY Dog Door

Customization is the key benefit when it comes to building a DIY dog door. Store bought dog doors tend to come in a limited range of sizes and materials, and may not work for all door sizes. 

So, before you make a trip to your local hardware store, consider these benefits of the DIY dog door:

  • Multi-dog (or chunky dog) accommodations: If you live in a multi-dog home with dogs of all shapes and sizes, you’ll soon discover that the store bought dog door sizes are quite limited. With a custom dog door, you can adjust the height and width to easily accommodate your pup or pups.  
  • Cost effectiveness: Dog doors tend to run the gamut of prices, but many DIY options can be made using materials you’ve already got in your home. A lot of plans utilize scrap wood, metal, plastic, or other products. You’ll recycle and save money with your DIY dog door!
  • Make your own security features: Generally speaking, a lot of the dog doors available for purchase are bare bones – just frame and flap. You’ll have to find creative ways to add your own security features. Many DIY plans offer solutions for sealing off the gaping hole in your door for security and pest avoidance.

Dog Door Size: How Big Does Your Dog Door Need to Be?

When sizing up your dog door, you’ll want to avoid the discomfort (and potential humiliation) that comes from making a door that’s too small. On the other hand, a door that’s too big may allow in unwanted, or downright dangerous, critters into your home. 


As a rule of thumb, the height of the flap should be your dog’s height, from floor to shoulder, plus an inch. That additional inch of clearance is vital to an easy entrance and exit from your pet door, and will avoid unnecessary strain on the back. 

Generally, in terms of width, the same rule applies – an extra inch adds a little extra space in case your pup packs on an extra pound or two.

You’ll also want to make sure that your pet can easily step through the door, and that the hole you’ve cut isn’t too high up. A general measurement is that your pet shouldn’t have to step over more than 1/3 of his height to get through the door. 

If you live in a multi-dog home, you’ll want to make sure that all your dogs’ measurements receive equal consideration. You’ll need to accommodate the widest and tallest for the size of the hole, and the shortest for the height of the door

The Benefits of Dog Doors

It’s important to note that in most cases, your dog shouldn’t have unmitigated access to the outdoors when you’re not home.

Conventional dog fences can have holes, electric fences can break down, and outdoor predators like coyotes can come out of nowhere. 

However, for the times when you are home, a dog door can, quite literally, open up a host of new possibilities for both you and your furry best friend. 

While daily walks and regular attention are, of course, a must, the freedom to go outside on a whim will cut down on the time you spend on bathroom breaks, so you’ll have more time for quality bonding. 

Here are some of the top reasons why you’ll want to consider a dog door:

They Help Combat Boredom

If you have a physical or electric fence, a dog door is a perfect pairing to allow for outdoor recreation on good weather days. From lounging in the sun to exploring the different smells in the yard, outside time is far more interesting for doggos.

Being cooped up inside can contribute to poor behavioral choices and anxiety – a bit of freedom in the outdoors offers a chance to release excess energy and enjoy a change of pace. 

They Provide Convenience

If you work from home, you’re busy with kids, or swamped with household projects, you may not have ample time to stop and take your pooch for a walk around the block at his beckon call.

Dogs sometimes send mixed signals, and sometimes their requests for a bathroom break may be a request to go outside and sunbathe. With a dog door and a properly house-trained dog, you and your pet can get your business done simultaneously, allotting more time for quality bonding.

They Give Your Dog a Means of Quick Escape

Nobody wants to think about it, but house fires and other disasters unfortunately happen. In the unlikely event of a fire, a doggy door provides a quick way out for your pooch that he might not otherwise have. 

Of course, this contradicts the general rule that dogs shouldn’t be given unsupervised outdoor access. But, in some cases, it may be the best option for you and your pooch.

You’ll just have to weigh the risks of allowing your dog outdoor access when you’re not home against the risks fires represent.
