🛠️ How to Install a Pet Door in a Hinged Door
1. Preparation
“Install a pet door yourself and save money with our easy-to-follow guide. We’ll walk you through every step, from choosing the right door to installing it.”
2. Measure Carefully
“The width of the pet door should be about 2″ wider than the widest part of your pet for comfortable use.”
“To choose the correct flap size, you will need to measure your pet to find what pet door width, height, and step-over you will need.”
“The top of the pet door flap should be at least 1″ above the tallest point on your pet’s back.”
“For maximum ease of use, the step-over height should never exceed ⅓ of your pet’s height.”
3. Choose Location & Door Type
“Your dog door should be installed in a door that is easily accessible by your pet—ideally, in a door near their main living area.”
“A regular hollow core door is the easiest to install a pet door in; complexity increases with metal or panel doors.”
4. Template & Drill
“Tape the provided template on the door.”
“Drill holes at the corners of the outline using a ½-inch drill bit to make cutting easier.”
5. Cut the Opening
“Begin in one corner and insert the blade into the ½-inch drill hole. Carefully continue along the pencil line to cut the outline of the pet door.”
“Cut the opening for the dog door with a hand saw. Start in one corner and cut along the outline you made with the template.”
6. Fit & Frame
“Insert the interior and exterior frames on either side of the door. Make sure the frames are flushed with the surface of the door. Use a level to make sure the frames are even on both sides.”
7. Secure the Door
“Hold the pet door in place and tighten the screws. Make sure you tighten them until they are just fixed and not overly tightened.”
“From outside the house, insert the side with no flap into the outer frame of the dog door. … Insert the interior frame of the dog door on the interior side of your door. The one with the flap is the interior side.”
8. Seal the Edges
“Use caulk to seal the inner part of the outer frame. This will help keep outside air from entering your home.”
9. Final Adjustments & Training
“After you have successfully installed and sealed the pet door, it is time to introduce your furry friend to their new entrance.”
“Stand on the other side of the door with a treat to coax them through… Once they’ve done it and realised it’s harmless, there’ll be no stopping them!”
🧰 Quick Tips for a Strong, Clean Install
-
Always measure your dog first – width, height, step-over – to pick the right size door.
-
Drilling pilot holes before cutting helps keep edges neat.
-
Use a level when fitting the frames so doors close properly.
-
Caulk fully around the outside frame to prevent drafts.
-
Train your dog with treats to ensure they know how to use it.

The Best Temporary Dog Door For Hinged Doors
If you have a hinged door, and your dog needs to be let out in a hurry, you can use one of these temporary dog door inserts. They’re designed to fit into the space where the knob and deadbolt would be on a regular door.
The idea is that you open the door, and then slip the insert into place. Your dog will go through it as if it were any other doorway.
The best part is that many of these temporary dog doors are designed so that you can remove them after your dog has used them. There are several designs available, but they all work in essentially the same way. Here are some of our favorites:
PetSafe Deluxe Patio Panel (Amazon) This is one of our favorite temporary pet doors for hinged doors because it’s easy to install and comes with everything you need to get started right away — including an instruction manual!

A temporary dog door for hinged doors is a convenient way to give your pet access to the outdoors. There are several different types of temporary pet doors available, each with its own advantages and disadvantages.

The Snap-EZ Pet Door is made from plastic and can be installed in minutes without any tools or drilling. However, it does not offer as much protection from wind or rain as other options and may not fit doors with thick frames.
The PetSafe Freedom Aluminum Patio Panel is similar to Snap-EZ in that it requires no tools or drilling to install and has no moving parts that could break down over time. It also allows you to install multiple panels on multiple doors so that more than one pet can use it at once.
