The 10 DIY Dog Door Plans

1. 5-Minute Doggy Door by frankenfoamy

Materials Door mat, ½“ PVC pipe, paint stick, screws
Tools Drill
Difficulty Level Easy

If you’re dipping your toes into the DIY pond of projects for the first time, anything that takes only 5 minutes sounds like a dream. This doggy door by frankenfoamy is a simple build using a car floor mat and a PVC pipe. The owner built it into a sliding window that leads out into an enclosure for his dog to do its business.

Granted, it’s not the nicest-looking dog door, but the builder clarifies that the build is temporary until he can develop something better. This is a great idea for desperate dog owners needing a doggy door yesterday!


2. Pet Door in a Screen Door by Heather’s Handmade Life

Materials 24.5” vertical boards (2), 3” spring hinges (2), 10” horizontal boards (2), paint (optional), cabinet door knob (optional)
Tools Drill, scissors, paintbrush(optional)
Difficulty Level Easy

If you have a screen door, don’t be nervous about cutting into it to make a dog door. This plan by Heather’s Handmade Life offers peace of mind to dog owners with its simplicity.

This dog door deserves a prize for being the cutest build that’s equally affordable. It looks like a door you’d see in Alice in Wonderland, complete with a doorknob. The door is attached with spring hinges, so it can automatically swing shut after your dog pushes it open.


3. An Almost Indestructible Doggy Door by Grandma’s House DIY

Materials Mud flaps, magnet rolls, Gorilla Glue
Tools Box cutter, measuring tape
Difficulty Level Easy

Durability is a big reason why many dog owners choose to build a dog door. The doors found online often don’t last very long, but a homemade door can last a lifetime if built correctly.

This plan by Grandma’s House DIY uses a basic dog door design with mud flaps and magnet rolls. Usually, you see mud flaps flapping behind the back tire of a big truck. They’re designed to protect the vehicle from dings and dents.

As a dog door, they work wonders at keeping the cold air out and lasting much longer than your typical dog door. The best part? No drill required! All you need is a box cutter, measuring tape, and some gorilla glue.


4. Magnetic Dog Door Flap by Crystal Reimche

Materials Magnetic tape, vinyl floor runner, duct tape, contact cement
Tools Box cutter, scissors, jigsaw
Difficulty Level Easy

If you want to ensure the dog door stays shut at all times, try this plan by Crystal Reimche. The dog door has magnetically sealed flaps designed to keep the cold air out. However, your dog can still push the flaps open with ease.

The interesting part about this plan is that it uses an inner flap and outer flap to make entering the house easier for the dog.

You don’t need a drill to make this dog door. All you need is a box cutter, scissors, and the required materials. However, you might need a jigsaw if you haven’t cut into the door before. The builder uses contact cement, but you can also try Gorilla Glue.


5. Dog Door Out of a Window by ExquisiteDobermans

Materials Plexiglass, cinder blocks, concrete, swing hinges, 1’ x 3’ board
Tools Table saw, drill
Difficulty Level Moderate

Instead of cutting into a wall or door, why not build the dog door into the window? This plan from ExquisiteDobermans uses durable plexiglass for the door and concrete-filled cinder blocks as steps outside the window.

This plan doesn’t have a list of materials except for what’s mentioned in the video. We’ve listed it as a moderately difficult design since you’ll have to figure out what materials and tools you’ll need.

The builder does show a finished dog door next to a work-in-progress dog door, so you can see how it looks in different stages of the build.


6. The Two-Flap Solution by gwylan – Instructables

Materials Plywood (14” x 17” x 1/4”), multiwalled plastic sheet (10” x 13”), magnets (2), butt hinges (2) with 12½” or 5/8” screws, ¼” x 10” oak dowel, fine wire, eyebolts (2), scrap wood, 5” strip of galvanized sheet metal  & four 3/4” screws, weatherstripping, wood glue, finishing nails (optional), silicone sealant, duct tape, isopropyl alcohol
Tools Saw, drill, utility knife, ruler, hammer, screwdriver, clamps (optional), chisels, mallet (optional), pencil
Difficulty Level Moderate

This plan by gwylan on Instructables is another method of keeping the door overlapped around the hole instead of just filling the opening. The previous plan we mentioned that had a similar build used a vinyl floor runner, but this build uses a multi-walled plastic sheet, a thicker and sturdier material.

There are quite a few materials and tools that go into this build, so it won’t be a cheap plan for new DIYers. But if you have many of the listed items, the door is a great affordable option.

The plan itself is straightforward and should be an easy build for anyone that’s worked with wood before. If you haven’t worked with wood, this is a nice challenge but certainly not impossible.


7. Another Screen Door With Dog Door by Famous Artisan

Materials 1’ x 4’ board (3), 1’ x 3’ board, 1 roll of spline, 1 roll of screen, 3 screen frame kits, window screen clips, swing hinges, handle kit
Tools Miter saw, table saw, finish nailer, brad nailer, chisel, quick clamps, hack saw, spline roller
Difficulty Level Hard

This plan from Famous Artisan is a seven-step process to adding a dog door to your screen door. Cutting into a screen door isn’t difficult, but this specific build requires you to be savvy with a few different saws. For that reason, we’ve listed this plan as challenging.

This build uses swing hinges so your dog can come and go as it pleases without leaving the flap open. There’s no inner or outer layer, so the springs will work both ways.

The finished product looks great. If you already feel comfortable using the required saws, this build will be a breeze.


8. Doggy Door Through Brick Wall by Sidney Jones

Materials PetSafe wall entry pet door, flex tape, white paintable latex caulk
Tools Drill, masonry drill bit set (5 pc), 6” double edge wallboard saw, 4½” 4.3 amp angle grinder, 4½” metal/masonry grinding wheel, chisel, hammer, measuring tape
Difficulty Level Hard

You don’t see many dog door plans that cut through brick, but this plan from Sidney Jones does! Cutting through brick isn’t easy, so don’t plan on this build being a piece of cake. You will need specific tools to complete this plan.

Thankfully, it only takes three steps to complete. Once it’s done, it looks fantastic. We highly recommend this plan for anyone wanting to cut through brick on the exterior of a home.

Materials: Flap (rubber or plastic), glue, screws, aluminum strip
Tools: Ruler, drill, sawhorses, jigsaw, sander, scissors
Difficulty: Easy

Even if you aren’t a DIY expert, you should find this plan within your grasp. It’s a beginner-friendly plan that lays out exactly what you need to do using very simple tools. You will need a jigsaw and sawhorses, though, so you may need to purchase some tools if you don’t already have them.

With all that said, this is one of the easiest and least expensive plans on this list.

Types of Pet Doors

So, which pet door is right for you and your dog? That depends on your level of experience and your living situation. It helps to know what kind of dog doors are available so you can make the best decision.

  • Installed in a Door: These are the most common pet doors. They’re cut into a wood, plastic, or screen door.
  • Installed Into a Wall: The next most popular door is installed into a wall anywhere in the house.
  • Sliding Glass Door Inserts: Inserts are premade vertical glass panes with a dog door attached. These easily slide into the sliding glass door space and create a section for your dog to come and go.
  • Built-In Pet Door: Many building companies will build doors with built-in pet doors already installed.
  • Electronic Pet Door: These pet doors operate off of the pet’s microchip and only open when the pet is nearby.

What Can I Use Instead of a Doggy Door?

A reason why dog doors don’t work out for many homeowners is the flap itself. It tends to warp over time and doesn’t connect to the magnet when this happens.

If you don’t want to use a basic dog door, you don’t have to. This list is proof that you can use just about anything as long as it works for you and the dog. Some of the materials the builders used in this list include:

  • Car floor mat
  • Mud flaps
  • Wood and screen
  • Vinyl floor runner
  • Plexiglass
  • Plastic sheets

The possibilities are endless. You just have to get creative and think about what is most important to you at this point. Do you need something quick and easy? Do you need something durable and long-lasting? Whatever it is, really think about the potential of different materials.

Summing Up

The best part about this list is a dog owner’s creativity who needed a fast and affordable solution. It’s fun seeing how people come up with their own version of dog doors and bring them to life.

There are plenty of options for you to try, so don’t give up just because a plan looks hard. You’ll make some mistakes, but that’s the fun part of learning a new skill. We hope this list gave you some ideas and inspired you to try something new!
