If you’re stuck in the “dog and door” struggle right now, I get it. My dog used to bark, scratch, and throw full drama at the back door every time he wanted out. It felt like I was a full-time doorman.
That’s when I started looking into dog doors. At first it sounded scary: security, weather, training… but once I understood the options, it actually made life easier for both of us. In this guide, I’ll walk you through everything I wish I’d known before cutting a hole in my door or wall: types of dog doors, sizing, safety, training, and even how to make the dog and door setup look good in your home.

How A Dog Door Changes Everyday Life For You And Your Dog
Here’s the thing: a dog door is really about freedom. Your dog gets to go out to pee, sniff, or sunbathe without shouting at you every hour. You get fewer interruptions during meetings, less scratching on your main door, and fewer “oops” accidents inside. For many owners, it’s a big win for house training and keeping a routine.
But it’s not for everyone. If your yard isn’t fenced, your dog is an escape artist, or you live in an area with a lot of wildlife, you’ll have to think more carefully about whether a dog door makes sense. In very hot or very cold climates, you also need a better insulated dog door so you don’t waste energy.
On top of that, a dog door changes the way your dog thinks about the house. They learn, “This is my exit.” Once my dog figured that out, he stopped pacing and whining in front of the main door. It’s a small thing, but it made the whole home feel calmer.
Quick Comparison Guide: Dog Door Types
| Dog Door Type | Best For | Pros | Cons |
| Door with built-in dog door | Homes with backdoors | Easy access, natural for dogs | Door must be modified |
| Dog doors for walls | Side yards, hidden exits | Flexible placement, discreet | Requires drilling through wall |
| Sliding glass/panel doors | Rentals & temporary setups | No permanent damage, removable | Narrows doorway |
| Screen dog doors | Light use, indoor–outdoor airflow | Cheap, easy to install | Low security & weatherproofing |
| Automatic/sensor dog doors | Security-focused homes | Only opens for your pet | Higher cost, needs power |
Quick Step-By-Step Guide: How to Choose the Right Dog Door
- Measure your dog
Height, width, and step-over height matter more than anything else. - Choose the installation spot
Door, wall, sliding panel, balcony, or screen — pick the safest location. - Consider your climate
Hot/cold regions need insulated or double-flap doors. - Decide on security level
Standard lock, security panel, or smart/automatic dog door. - Plan training in advance
A few calm sessions with treats make a huge difference.
Is A Dog Door Right For Your Dog, Home, And Routine
Before you start shopping, ask a few honest questions about your dog:
- Are they old, arthritic, or very tiny?
- Are they nervous, fearful, or easily spooked by moving things?
- Do they chase cats, birds, or anything that moves?
If your dog has mobility issues, you’ll want a low step and maybe a ramp. If they’re anxious, you’ll need extra patience with training. High prey drive dogs can still use a dog door, but you’ll need a secure fence so they don’t run off chasing squirrels.
Then look at your home and lifestyle. Do you rent or own? Do you have a fenced yard? Are there kids who might leave doors unlocked? If you’re away from home for long hours, a dog door can be a lifesaver, but only if the outdoor area is safe, shaded, and secure. Think of it this way: a dog door is like giving your dog a key to one part of your world. You want to make sure that “world” is safe first.
Main Types Of Dog Doors And Where They Work Best
When I first Googled dog doors, I was shocked at how many types there are. Let’s keep it simple and walk through the main ones.
Door With Built In Dog Door
This is the classic setup: you cut an opening in your regular back door and install a flap. Some companies even sell a full door with built in dog door already installed from the factory.
This option works great if:
- You own your home
- Your main back door is in a convenient spot
- You don’t mind modifying the door
The best part is that it feels very natural for the dog. “This is the door we always used, now it has my little door in it.” Just make sure the height is right and you choose a model with decent insulation and a dog door with lock so you can close it at night or when you travel.
Dog Doors For Walls And Hidden Corners
Dog doors for walls are exactly what they sound like: instead of going through a door, you go through an exterior wall using a tunnel-style dog door. This looks scary at first, but pro installers do it all the time.
Wall doors are awesome when you want the exit to be in a more “hidden” spot. Some popular dog door ideas for wall placement are:
- Laundry room leading to the side yard
- Mudroom opening straight to the garden
- A quiet corner near the patio
I love this style because it can be more secure and less noticeable from the street. It also gives you more freedom with dog and door design, since your main doors stay untouched.
Full Panel, Sliding, And Screen Options
If you’re renting or don’t want to cut anything permanent, you’ve still got options. A dog door full door panel can replace part of a sliding glass door, or you can get a panel that fits into the track of your sliding door, giving your dog their own flap on the side. There are also dog doors that fit into screen doors or magnetic screen “curtain” styles that open and close as your dog passes through.
These are perfect if:
- You need something removable
- You want to test a dog door before committing
- You use your patio or balcony a lot
The tradeoff is that panels can narrow your walkway, and screen setups are less secure and less weatherproof. But for apartments and rentals, they’re a very practical solution.
Automatic Dog Doors And Dog Door With Sensor
Now let’s talk tech. Automatic dog doors open and close using a collar tag, RFID, or your pet’s microchip. A dog door with sensor only unlocks when your dog is at the flap, so random neighborhood cats or wildlife can’t stroll in.
These electronic dog doors are great for:
- Multi pet homes where only some animals are allowed outside
- Areas with raccoons or stray cats
- People who worry a lot about security
They cost more, and you’ll need power near the door, but if you’re paranoid about who (or what) might come through the dog and door setup, automatic dog doors can be worth it. Think of them as a smart lock for your pet.
How To Measure Your Dog And Door Opening The Right Way
I swear, measuring correctly is the most “boring but important” part of this whole process. If you get the size wrong, your dog might hesitate, bump their back, or just refuse to use the door.
Basic Measuring Steps
Grab a tape measure and have your dog stand naturally (no stretching). You’ll want to measure:
- Height: from the floor to the top of their shoulders
- Width: the widest part of their chest or hips
The top of the flap should be at least as high as the top of their back, preferably a little higher so they don’t have to crouch. For the step over (the bottom of the flap), try to keep it low enough that your dog can step through without jumping, especially if they’re older.
The same logic applies whether you’re using a door with built in dog door, a wall entry, or a panel. The model and style don’t matter as much as getting that height and step right.
Special Cases: Puppies, Seniors, And Multi Pet Homes
If you’ve got a puppy, measure their parents or ask your vet what size they’ll likely grow to. You don’t want to buy three different doors in two years. For senior dogs, big breeds, or short-legged cuties like corgis, go for a lower step or add a small ramp outside.
In multi pet homes, you might have a small dog and a big dog (or even a cat) using the same dog door. Aim for a flap height that’s high enough for the big dog, then use a low step or ramp so the smaller one can still reach it comfortably. It takes a bit of planning, but it’s totally doable.
Safety, Security, And Weather Protection For Dog Doors
One of the biggest fears people have is security. “If my dog can get out, can someone get in?”
Dog Door With Lock And Extra Dog Door Barriers
Most modern dog doors come with some form of dog door with lock: sliding covers, interior panels, or extra security plates you can put in at night. It’s not a full bank vault, but it adds a basic barrier.
You can also create your own dog door barrier inside the house using:
- Baby gates to block access to the dog door when needed
- A playpen around the outside area
- A fenced yard with a locked gate
The idea is to treat the dog door like another entry point in your security plan, not a random hole in the wall you never think about. When we travel, we slide in the cover, lock the gate, and I feel pretty relaxed about it.
Weather, Bugs, And Energy Efficiency
If you live somewhere cold or super hot, don’t cheap out on the flap. Look for insulated models, double flaps, or doors designed for “extreme weather” so you’re not losing heating or cooling through the opening.
Good seals and magnets help keep the flap closed in the wind and reduce bugs coming in. And if you go for dog doors for walls, the tunnel can actually help with insulation when installed properly. Little details like this matter for both comfort and your energy bill.
Training Your Dog To Use The Dog Door Confidently
My dog stared at the flap like it was a portal to another dimension when we first installed it. So if your dog is confused or scared at first, that’s totally normal.
Step By Step Training Plan
Start simple: hold the flap open and toss a treat just outside. Let your dog walk through without anything touching them. Once they’re comfortable going through, lower the flap so it brushes their back a little. Reward generously.
After a few sessions, let the flap close fully and call them through from the other side. Use a happy voice, lots of praise, and don’t rush. Short, fun sessions (5 to 10 minutes) work better than one long stressful one.
I swear, teaching my dog to use the dog door was easier than potty training. Once he realized that going through that little door meant freedom to sniff and explore, he started using it without any help.
Fixing Common Dog And Door Problems
If your dog is scared of the flap sound, you can temporarily tape it up or remove a couple of magnets so it swings more lightly, then gradually restore it once they’re used to it.
If they still scratch the main door instead of using the dog door, gently guide them to the flap each time. Sometimes I would ignore the scratching, walk calmly to the dog door, and call him there. After a week of being consistent, he finally “got it.”
And if they only use the dog door when you’re standing nearby, try doing a few “fake” exits: go outside, call them through, reward, then go back in. It helps build confidence that they can use the door independently.
Dog And Door Design Ideas That Look Good In Your Home
Let’s be honest: no one wants their house to look ruined just because they added a pet door. The good news is, you can make your dog and door design look pretty stylish.
Clean, Matching Dog And Door Design
Pick a frame color that matches your main door or trim. Many pet doors can be painted, especially wall models, so they blend in instead of shouting “DIY project!”
If you’re using a door with built in dog door on a farmhouse-style back door, go for simple, clean lines. For modern homes, slim frames and neutral colors look best. Small design choices like this can turn a practical dog door into something that looks intentional.
Smart Layout Ideas For Small Homes And Rentals
In smaller homes or apartments, placement matters a lot. Putting the dog door in a low-traffic area (like near the laundry or balcony) keeps mud and fur away from your main living space. A wall dog door leading to a small side yard can be a game changer.
Add:
- A mat inside and outside to catch dirt
- A small bench or storage by the door for leashes and towels
- A removable panel or screen style dog door if you’re renting
That way, your dog has freedom, but your home still feels tidy and put together.
Simple Buying Checklist Before You Order
Before you hit “buy,” run through this quick checklist:
- Where will it go? Main door, wall, sliding glass, or screen?
- Do I want a basic flap, or do I need automatic dog doors with sensors or microchip access?
- Have I measured my dog’s height and width carefully?
- Is the step over low enough for my smallest or oldest pet?
- Do I need extra security, like a strong dog door with lock and a fenced yard?
- What’s my climate like, and do I need an insulated or double flap model?
If you can answer these clearly, you’re ready to choose the right dog and door setup without second-guessing yourself later.
FAQs About Dog Doors And Everyday Use
Are dog doors safe for home security?
They can be, if you choose the right size, use a locking cover, and have good fencing. A small flap that only fits your dog is usually not a realistic way for a burglar to get in.
Can other animals get in through the dog door?
Yes, especially in areas with raccoons or stray cats. That’s where a dog door with sensor, microchip dog door, or automatic dog door really helps, because it only opens for your pet.
What if my dog is afraid of the dog door?
Go slow, use treats, and never force them. Hold the flap open at first, then gradually let it touch their back, and reward every success. Most dogs just need time and patience.
Can I use one dog door for both dog and cat?
Yes, as long as the size and step height work for both. Many people do this with selective entry electronic doors so the cat doesn’t wander off if you want them indoors.
Conclusion: Building A Safe, Easy Dog And Door Routine
At the end of the day, a dog and door setup is about making life smoother for both of you. When you choose the right type of dog door, measure carefully, think about safety, and put in a bit of training, it stops being a headache and turns into one of those upgrades you wish you’d done sooner.
My dog doesn’t bark at the door every hour anymore. He slips in and out through his little door, chills in the yard, and comes back when he’s ready. And I can finally drink my coffee hot.
If you’re on the fence, start with your checklist, pick the style that fits your home, and commit to a week of gentle training. You might be surprised how quickly your dog learns the new routine and how much more peaceful your days feel once the dog and door work together instead of against you.
FAQs:
1. Who invented the doggy door?
The idea is credited to Sir Isaac Newton, who reportedly cut small holes in his wooden door so his cat could come and go. Over time, the concept evolved into modern dog and pet doors.
2. What is the best dog door?
The best dog door depends on your home and lifestyle. For most people, insulated door-mount dog doors work best, while households needing security or wildlife protection often prefer automatic or sensor-based dog doors.
3. Do dogs share 99.9% DNA with wolves?
Dogs share about 99.8% DNA with wolves. That’s why their instincts — like exploring, guarding territory, or wanting outdoor access — still show up today.
4. Why don’t people have doggy doors anymore?
People still use dog doors, but many prefer smart dog doors, panel inserts, or wall-mounted designs for better security, insulation, and control. Traditional flap doors are still common but aren’t ideal for every home.
5. Are dog doors safe at night?
Yes, if you choose a dog door with lock, a secure panel, or an electronic door that only opens for your pet. Most owners simply close the locking cover before sleeping.
