dog and door
According to American Kennel Club and tupgrades:
If you’ve ever found yourself playing doorman for your dog—opening the door every time they want out, then in again a few minutes later—you’re not alone. Many dog owners eventually reach a point where they start thinking seriously about installing a dog door. Whether it’s for convenience, better potty routines, or giving your dog a little independence, a dog door can transform daily life. But choosing the right one? Installing it correctly? Making sure your dog actually uses it? Those are the real challenges.
In this guide, we’ll break everything down step by step. We’ll explore how to pick the right dog door, what to expect during installation, how to train your dog to use it confidently, how to keep unwanted critters out, and even how to fix those annoying scratching behaviors many dogs develop around doors. Along the way, you’ll find expert references
Let’s dive in.
Choosing the Right Dog Door (Selection & Sizing)
How do I measure my dog for a dog door?
Picking the right dog door starts with accurate measurements. You want your dog to walk through comfortably—without ducking too low or squeezing too tight.
Here’s the simple way to measure:
1. Height
Measure from the ground to the top of your dog’s shoulders (the withers). Then add about 2–3 inches for comfort.
2. Width
Measure the widest part of your dog’s body—usually the chest or hips. Add 1–2 inches to avoid rubbing.
3. Rise
The “rise” is the height from the ground to the bottom of the dog door’s opening. This matters because the dog should be able to step through without jumping.
Experts often recommend keeping the rise low, especially for senior dogs or breeds prone to joint problems. large dogs with hip or knee issues benefit from lower step-over thresholds to reduce strain.
What size dog door do I need for my breed?
According to RANGER Pet Doors Canada and Pet Lover Guy:
Different breeds have different build styles. A Greyhound and a Golden Retriever might weigh the same, but their body shapes differ drastically.
Here are quick examples:
- Small breeds (Yorkies, Chihuahuas): Small or extra-small flaps
- Medium breeds (Cocker Spaniels, Beagles): Medium flaps
- Large breeds (Labs, Goldens, Boxers): Large flaps
- Giant breeds (Great Danes, Mastiffs): Extra-large or tall dog doors
dog doors should accommodate a dog’s largest body measurement—meaning winter weight changes, thick coats, or aging mobility shouldn’t turn the door into a squeeze box.
What are the different types of dog doors available?
According to PlexiDor Dog Doors and This Old House and petwithit and petsmart:
There isn’t just one type of dog door—there are several, each with its own benefits:
Flap Dog Doors
These are the classic, flexible flaps that dogs push open. They’re inexpensive, simple, and easy to install.
Electronic/Smart Dog Doors
These doors open only for your dog, using:
- Microchip sensors
- RFID collars
- Magnetic keys
According to PetMD, smart dog doors significantly reduce the risk of intruders—like raccoons or stray cats—coming in.
Sliding Glass Door Inserts
A great option for renters or people who don’t want to cut through a wall or door.
Wall-Mounted Doors
These give you freedom to choose the perfect placement—even if it’s through brick or siding.
Are electronic/smart dog doors worth the extra cost?
For many owners, yes. The biggest value comes from security and control.
Sensors: Microchip vs Magnetic
According to petolog and VCA Animal Hospitals:
- Microchip Sensors: More reliable; only open for your dog’s actual microchip.
- Magnetic/Collar Keys: Cheaper, but if your dog loses the collar, the door won’t open.
Smart doors are especially useful for:
- People with wildlife nearby
- Those living in apartments
- Owners who want timed access (like allowing nighttime access only)
What is the best dog door for extreme weather or cold climates?
According to petsafe and RANGER Pet Doors Canada and dogster and protechreview:
If you live somewhere cold or windy, don’t go for a thin flap. Insulated dog doors are a lifesaver.
Look for:
- Double or triple-flap systems
- Magnetic seals
- Automatic closing
- Insulated frames
Some high-end models even use airtight locking systems that help maintain indoor temperature.
Installation Logistics (Feasibility & Cost)
Can I install a dog door in a glass sliding door?
According to fixr and pet door products:
Yes. The easiest method is using a sliding glass door insert, which fits between your door frame and the glass panel. No cutting needed.
If you want a built-in glass dog door, a glazier must cut tempered glass—not a DIY project.
Is it better to install a dog door in a wall or a door?
According to fixr and pet door products:
Both options work, but each has pros and cons.
Door Installation
- Easier
- Cheaper
- Faster
Wall Installation
- More permanent
- Cleaner look
- Works when door placement is awkward
If you’re unsure, door installation is normally the safer starting point.
How much does it cost to have a dog door professionally installed?
According to fixr and homeguide:
Pricing varies based on the type of door:
- Basic door flap: $100–$200
- Wall dog door: $300–$700
- Glass dog door: $400–$1200
- Smart dog door: $500–$1500 installed
Professionals charge more for cutting through stucco, brick, or double-glazed glass.
Can I install a dog door in a rental property without damaging the door?
Yes—your best options include:
- Sliding glass inserts
- Window panel dog doors
- Temporary panel doors for patio sliders
These can be removed without leaving a mark.
How do I seal a dog door to prevent drafts and leaks?
According to Homes and Gardens and Sharp Glass Services:
To prevent wind, bugs, and rain from sneaking in:
- Use weatherstripping
- Choose doors with strong magnets
- Add insulation tape around the frame
- Consider double flaps for extreme weather
According to PetMD, heat loss through pet doors is common, but high-quality seals prevent this almost entirely.
Training & Usage (The “How-To”)
How do I train my dog to use a doggie door?
Training doesn’t have to be complicated. Here’s a simple method:
1. Prop the flap open
Let your dog see the outdoor space clearly.
2. Use treats
Call your dog through. Celebrate big when they make it.
3. Practice from both directions
Some dogs are brave going out but hesitant coming in.
4. Close the flap halfway
Gradually reduce visibility until your dog pushes through confidently.
Why is my dog afraid of the dog door flap, and how can I fix it?
Flaps make noise—and sensitive dogs may get startled.
Try this:
- Tape the flap open
- Slowly lower it over sessions
- Let your dog explore without pressure
- Feed treats near the flap so they associate it with something positive
How do I teach my dog to use the door without getting their tail caught?
According to dial a vet and petdoors:
A well-sized door shouldn’t trap tails. Still, to build confidence:
- Guide your dog through slowly
- Use a lightweight, flexible flap
- Practice with the flap lifted at first
Dogs naturally adjust their tail position after a few successful passes.
My dog used the door before but suddenly stopped—why?
According to dial a vet
Sudden refusal can mean:
- Something scared them (a noise, another animal)
- Pain or injury
- A stiff flap
- Weather changes (wind blowing the flap hard)
Check for any physical blockages or stiff hinges. If nothing’s wrong, retraining with treats usually restores confidence.
Safety, Security & Intruders (Peace of Mind)
Are dog doors a security risk for burglars?
According to Sharp Glass Services and racv and Reader’s Digest:
A small dog door can’t fit a person, but larger ones might. To reduce risks:
- Install electronic access control
- Use locking covers
- Choose high placement
- Add motion sensor lights nearby
PetMD explains that smart dog doors significantly reduce risk because they remain locked unless triggered by your dog’s microchip or collar key.
How do I stop other animals (raccoons, stray cats) from coming through the dog door?
Animals are attracted by smell—mainly food bowls near the door. Try:
- Using microchip-controlled doors
- Keeping pet food far away
- Adding motion-sensor repellents outside
Smart doors are the most reliable solution.
How can I lock or secure the dog door when we go on vacation?
Most dog doors come with:
- Slide-in locking panels
- Electronic “vacation mode”
- Security covers
You can also buy impact-resistant inserts that fully block the door while you’re away.
Is it safe to leave a puppy with access to a dog door while I’m at work?
According to petmd and iereand petmd:
Not usually. Puppies need supervision and can:
- Escape
- Wander off
- Encounter wildlife
- Eat dangerous objects outside
Limit access until they’re older and fully trained.
Behavioral Issues (Scratching & Damage)
Why does my dog scratch the door when he wants to go out?
Dogs scratch because:
- It works (the door opens!)
- They’re anxious
- They’re bored
- They want attention
Scratching becomes a habit when reinforced.
How do I stop my dog from scratching and damaging my doors?
You can reduce scratching by:
- Teaching a sit-and-wait cue
- Installing a dog door (so they go out independently)
- Using scratch-proof door guards
- Rewarding calm behavior
What are the best door protectors or shields for dogs?
According to ubuy and tupgrades and tupgrades:
Good options include:
- Clear acrylic shields
- Stick-on plastic sheets
- Metal kick plates
- Anti-scratch films
These keep the door looking new—even if your dog isn’t gentle.
Does installing a dog door actually stop door-scratching behavior?
In many cases, yes. Giving the dog independence reduces frustration and attention-seeking. According to PetMD, dogs scratch less when they can relieve themselves or explore outside without relying on humans.
