The best dog door for a wooden door is the PetSafe Plastic Dog & Cat Door in the small size, because it fits wood doors from 1/16 in to 2 in thick, includes a cutting template and has a paintable frame that blends into your door. For a drafty exterior door, the Baboni 3-Flap is the better dog door for a wooden door that faces weather.
Large dogs in cold climates should look at the PetSafe Extreme Weather.
A wooden door is the easiest place to fit a flap, since you can cut a clean opening with a jigsaw and screw the frame in on both sides. The hard part is picking the right flap size, thickness range and insulation level.
This guide walks through nine options so you can match one to your dog and your door.
Our pet door buying guide covers the full range of door and wall styles if you're still deciding where the opening should go.

The best dog doors for wooden doors, ranked by score
Every pick here is built to mount in a solid wooden door, so the choice comes down to dog size, door thickness and how much weather protection you want. Start with the highest score if you have an average door and a small-to-medium dog.
PetSafe Plastic Dog & Cat Door: Best for most wooden doors
- Fits doors 1/16 to 2 in thick
- Flap opening 5 1/8 x 8 1/4 in
- Paintable plastic frame
- Snap-on closing panel
A simple, affordable flap for small dogs and cats that suits most wooden doors and comes with a cutting template.
Pros
- Fits a wide range of wood door thicknesses
- Paintable frame matches your door color
- Snap-on panel controls access
Cons
- Small flap only suits pets up to 15 lb
- Plastic frame is less insulated than aluminum
This is the pick for most readers, and the reason is fit. The frame works in interior or exterior wood, PVC, metal and paneled doors from 1/16 in to 2 in thick, so almost any solid wooden door in a typical home qualifies.
A cutting template and step-by-step instructions are in the box, which keeps the DIY job simple.
The flap opening measures 5 1/8 in wide by 8 1/4 in tall and suits pets up to 15 lb. That is right for a cat or a small dog like a terrier or a miniature poodle.
The snap-on closing panel lets you close the opening when you want to keep your pet in or strays out.
Its white plastic frame is paintable, so you can match it to the door's color instead of leaving a white rectangle on a stained door. The single flap offers only modest draft control, which is the main trade-off against the insulated picks further down.
PetSafe backs it with a limited lifetime warranty when bought from an authorized retailer.
PetSafe Plastic Dog & Cat Door: Best for medium dogs on a budget
- Fits doors 1/16 to 2 in thick
- Flap opening 8 1/8 x 12 1/4 in
- Paintable plastic frame
- Snap-on closing panel
The same easy fit as the small version, scaled for dogs up to 40 lb on interior or exterior wood doors.
Pros
- Handles dogs up to 40 lb
- Wide door thickness range
- Paintable frame
Cons
- Snap-on panel is not a locking panel
- Single flap offers modest draft control
The medium version is the same door scaled up for dogs up to 40 lb, with a flap opening of 8 1/8 in wide by 12 1/4 in tall. That covers a beagle, a cocker spaniel or a border collie mix without forcing the dog to duck through.
It shares the same fit range of 1/16 in to 2 in thick wooden doors, plus the cutting template and snap-on closing panel. The paintable frame works on the same doors as the small model, so your color match stays consistent across both.
Where it beats the small version is simple: your dog fits. Where it falls short of the insulated doors is weather sealing.
One flap with a snap closure lets more cold air in around the edges than a three-flap design. If your wooden door is sheltered and your dog is medium-sized, this is the value pick.
Baboni Dog Door for Door: Best for drafty wooden doors
- Three-flap design
- Fits doors 1 3/8 to 1 31/32 in thick
- Magnetic closure
- Outdoor-grade thickened plastic frame
Three flaps block drafts and weather better than a single flap, so it suits an exterior wooden door that faces wind and rain.
Pros
- Three-flap insulation
- Magnetic flap seal
- Thickened outdoor-grade plastic frame
Cons
- Narrower door thickness range than the PetSafe plastic doors
- Only one size
Baboni's three-flap design is the reason to choose it. Two vinyl flaps with a magnetic closure sit around one insulated middle flap, so the opening seals against drafts better than a single flap.
For an exterior wooden door that takes wind or rain, that extra layer matters.
The frame is thickened outdoor-grade plastic rather than ordinary plastic, and the telescoping tunnel fits doors from 1 3/8 to 1 31/32 in thick. That range is narrower than the PetSafe plastic doors, so measure your door first.
The flap opening is 8 1/4 in wide by 12 1/4 in tall, and the door suits pets up to 40 lb.
Baboni also says the design improves thermal insulation, which helps your heating and cooling bill over time. The trade-off is the tighter fit range and the single medium size.
If your wooden door is thinner than 1 3/8 in or you have a large dog, look elsewhere in this list.
PetSafe Extreme Weather Aluminum Dog Door: Best for large dogs in cold climates
- Three-flap insulated design
- Aluminum frame with reinforced corners
- Fits doors 1 1/2 to 2 in thick
- Slide-in closing panel
A metal-framed, heavily insulated door for big dogs where winter drafts and summer heat matter.
Pros
- PetSafe says the 3 flaps block 3 times more thermal energy than a standard door
- Aluminum frame with reinforced corners
- Slide-in closing panel
Cons
- Needs a door at least 1 1/2 in thick
- Premium price tier
This is the door for a big dog in a real climate. The aluminum frame has reinforced corners and is built to handle multi-pet households, and the three insulated flaps with a magnetic seal are the weather-tight setup you want on an exterior wooden door.
PetSafe says the 3 flaps block 3 times more thermal energy than a standard pet door. The slide-in closing panel gives you a firm way to shut the opening when your dog is indoors.
It fits most exterior doors including paneled, wood, PVC and metal, from 1 1/2 in to 2 in thick.
The catch is that thinner wooden doors won't take it. If your exterior door is under 1 1/2 in thick, the standard PetSafe plastic door or the Baboni are better bets.
For everyone else with a large dog and cold winters or hot summers, this is the strongest weather choice.
Amazon Basics Adjustable Plastic Dog and Cat: Best for wide openings
- Large 9.5 x 16 in entrance
- Plastic construction
- Fits interior and exterior doors or walls
- All mounting parts included
A broad entrance opening at a budget tier, sized for cats and small dogs but with plenty of room to pass through.
Pros
- Wide 9.5 x 16 in entrance
- Works in doors or walls
- Budget price tier
Cons
- Plastic build has less insulation than aluminum
- Entrance is bigger than many small dogs need
Amazon Basics offers a broad entrance opening at a budget tier. The 9.5 x 16 in entrance gives a small dog plenty of room to pass through, and the plastic construction works in interior or exterior doors or even a wall.
All mounting parts and instructions are included.
It suits someone who wants a wide, simple opening without paying for insulation or a metal frame. The trade-off is the same as the single-flap PetSafe doors: plastic and a wide opening mean more air movement around the flap.
It also runs larger than many small dogs need.
If your dog is closer to medium size and you want the extra clearance, this is a sensible budget pick. If you need a tight seal on a windy door, spend a little more on a three-flap model.
PetSafe Wall Entry Telescoping Pet Door: Best for solid walls instead of doors
- Telescoping tunnel for 4 3/4 to 7 1/4 in walls
- Double flap
- Rust-resistant plastic frame
- Large size up to 100 lb
Skip the wooden door entirely when you have a solid wall that suits a tunnel installation for a big dog.
Pros
- Fits walls 4 3/4 to 7 1/4 in thick
- Double flap for weatherproofing
- Large size handles dogs up to 100 lb
Cons
- Not a door-mounted door
- Extension kits for thicker walls sold separately
Sometimes the wooden door isn't the right place for the opening. This telescoping wall-entry door fits walls from 4 3/4 to 7 1/4 in thick and handles dogs up to 100 lb, with a flap opening of 10 1/4 in wide by 16 1/4 in tall.
A double flap adds weatherproofing, and the plastic frame resists UV exposure.
It's a large size only, so it suits big dogs. The closing panel slides in to add insulation when your pet isn't using the door.
Extension kits for thicker walls are sold separately.
Choose it when a wall opening is easier than cutting your wooden door, or when the door itself is hollow-core or glass-paneled. It's the only wall-entry pick here, so skip it if you're set on fitting the flap in the door.
Petoasis 3-Flap Heavy-Duty Aluminum Dog Door: Best for active large dogs
- Aluminum alloy frame
- Three-flap insulated design
- Fits doors up to 2.4 in thick
- Locks inside and outside
A sturdy metal frame for big, busy dogs, with three flaps and locks on both sides of the door.
Pros
- Rust-resistant aluminum alloy frame
- Three-flap insulation
- Locks on both sides
Cons
- Higher price tier
- Large size only
Petoasis builds its frame from aluminum alloy rather than plastic or thin iron, and the result is a sturdier door for active dogs. The three-flap setup includes an insulation layer that Petoasis says blocks high heat, severe cold and humidity.
It fits doors up to 2.4 in thick and handles dogs up to 100 lb.
The locks sit on both the inside and outside, which gives you more control than a simple snap panel. All three flaps can be removed separately if a weaker dog needs an easier pass.
Petoasis also offers a replacement flap if one gets damaged.
The trade-off against the PetSafe Extreme Weather is price tier: this is a premium option. It's also large size only.
For a big dog that uses the door constantly and a wooden door up to 2.4 in thick, it's a solid long-term pick.
CEESC Large Dog Door: Best for tall dogs
- Flap opening 11.75 x 16.5 in
- Snap-in closing panel
- Magnetic bottom seal
- Fits solid wood, PVC and metal doors 1.25 to 2.06 in thick
A tall opening for leggy dogs up to 100 lb, with a magnetic seal and a snap-in panel for access control.
Pros
- Tall 16.5 in flap opening
- Snap-in closing panel
- Magnetic seal at the flap bottom
Cons
- Not for glass doors
- Needs landlord approval on rentals
CEESC targets leggy dogs with its 11.75 in wide by 16.5 in tall flap opening, sized for dogs up to 100 lb. The dual-layer ABS frame and snap-in closing panel add security and insulation, and the magnetic strip at the bottom keeps the flap shut against drafts and rain.
It fits solid wood, PVC and metal doors from 1.25 to 2.06 in thick. The removable flap has windproof and rainproof seals.
A bristle strip around the flap cuts down on gaps that let water in.
The limits are worth knowing: it isn't for glass doors, and renters need landlord approval before cutting. The snap-in panel controls access for night or training.
If your dog is tall rather than heavy, the extra flap height here is the reason to choose it over the medium PetSafe.
PetSafe Plastic Dog and Cat Door: Best for very large dogs
- Fits doors 1/16 to 2 in thick
- Flap opening 10 1/8 x 16 1/4 in
- Paintable plastic frame
- Snap-on closing panel
The largest of the PetSafe plastic doors, sized for big dogs up to 100 lb at a lower price than aluminum models.
Pros
- Handles dogs up to 100 lb
- Paintable plastic frame
- Snap-on closing panel
Cons
- Plastic frame insulates less than aluminum
- Single flap lets more drafts through
This is the largest of the PetSafe plastic doors, with a flap opening of 10 1/8 in wide by 16 1/4 in tall for dogs up to 100 lb. It's the affordable way to fit a very large dog in a wooden door without paying aluminum prices.
It shares the 1/16 to 2 in thickness range and the paintable frame with the smaller PetSafe plastic doors. The snap-on closing panel controls access.
A cutting template and instructions are included.
The catch is insulation. A single plastic flap lets more drafts through than a three-flap aluminum door, so this suits a sheltered or mild-climate door more than a windy one.
For a giant breed on a budget, though, it's the pick that makes the most sense.

How we compared these dog doors
We judged each door on how well it fits a solid wooden door, starting with the door thickness range and the flap size. A door that can't fit your door's thickness is out before anything else.
From there we weighed the dog weight limit against the flap opening, so the size claims line up with the dimensions. Then we looked at weather sealing, frame material and access control, since those are the features that decide comfort and security day to day.
Our score weighs specs, features and buyer feedback against what you're shopping for. A door that fits a wide range of wooden doors and seals well scores higher than one with a narrow fit range or a single flap.
What should you measure before cutting a wooden door?
Measure your dog and your door before you buy, then measure again before the saw comes out. The dog's chest width and shoulder height decide the flap size, and the door's thickness and construction decide which frames will fit.
Measure your dog's chest and height
Stand your dog and measure the widest part of the chest and the height from the floor to the top of the shoulders. Compare those with the flap opening, and leave a little margin so your dog walks through without crouching.
Check the door thickness
Measure the door at the spot where the flap will sit, using a caliper or a straight edge across the edge of the door. The PetSafe plastic doors take 1/16 to 2 in, the PetSafe Extreme Weather takes 1 1/2 to 2 in and the Baboni takes 1 3/8 to 1 31/32 in.
A door outside those ranges needs a different model.
Confirm the door is solid
A wooden door must be solid, not hollow-core, at the cut location. A hollow door has a thin skin and a cardboard or paper core, so the frame won't grip and the opening will weaken.
Check the edge of the door or knock on it to hear whether it sounds solid.
Check what's below the flap
Look for obstacles under the opening. If your dog needs to step over a threshold or down a step, the flap bottom should clear the floor enough for a safe step.
Also keep the flap away from any glass panels or decorative insets you don't want to cut through.
Which dog door for a wooden door suits your dog's size?
Match the dog to the flap opening first, then choose the door style. A small dog in a medium flap will squeeze through a gap that lets in cold air, and a big dog in a small flap won't fit at all.
Small dogs and cats
The small PetSafe plastic door handles pets up to 15 lb with a 5 1/8 x 8 1/4 in flap. It's the smallest opening in this group, so it wastes less space around a little dog.
For more small-dog options, see our roundup of the best dog door for small dogs.
Medium dogs up to 40 lb
The medium PetSafe plastic door and the Baboni both fit pets up to 40 lb with an 8 1/8 x 12 1/4 in flap. Pick PetSafe for the wider thickness range and the Baboni for the three-flap seal.
Large dogs up to 100 lb
The PetSafe Extreme Weather, Petoasis, CEESC and the large PetSafe plastic door all handle dogs up to 100 lb. Choose by insulation needs and door thickness.
The CEESC's 16.5 in flap height suits a tall dog best.
How do you handle weather and drafts on an exterior wooden door?
A three-flap design with a magnetic seal is the best defense against drafts on an exterior wooden door. Single-flap plastic doors let more air move around the edges and suit sheltered or mild-climate doors.
The PetSafe Extreme Weather is the strongest weather pick, with PetSafe claiming its 3 flaps block 3 times more thermal energy than a standard door. The Baboni and Petoasis also use three flaps.
If your door faces a windy direction or you get real winters, spend the extra on one of these rather than a single-flap model.
Adding a closing panel also helps when your dog is indoors. The slide-in panels on the PetSafe doors and the dual locks on the Petoasis give you a way to shut the opening on cold nights.
Can you fit a dog door in an exterior wooden door safely?
Yes, if the door is solid wood and thick enough for the frame. A dog door for wooden door use needs a solid core so the frame screws hold firmly and the opening stays rigid.
Check the door's thickness and construction first. An exterior door often has a solid wood or composite core, which is a good base.
A hollow-core exterior door is a poor candidate because the thin skin can split around the cut.
Also think about security. A dog door is an opening in your home, so choose one with a closing panel or lock that you can use when your pet is inside.
The snap-on and slide-in panels on these models cover that.
What else to know before you buy a dog door for a wooden door
Cutting a wooden door is a one-way decision, so plan the placement and the install order before you start. A few small choices make the job cleaner and the flap last longer.
Pick the flap position carefully
Place the flap where your dog already walks to the door and away from hinges or decorative panels. Leave enough room for the frame's screws on all sides.
The template in each kit shows the cutout size and screw holes.
Install with the right tools
You'll need a jigsaw, a drill, a pencil and a tape measure. Most kits include a cutting template.
Cut slightly inside the marked line and test the frame fit before screwing it in, since a snug fit seals better than a loose one.
Plan for the dog's routine
A flap works best when your dog already knows how to use the door. If your dog is new to a flap, hold it open and guide your dog through a few times before letting it swing closed.
A closing panel at night keeps strays out and helps your pet settle.
Consider a screen door instead
If your wooden door is your main entry, you might put the dog door in a screen door instead. Our guide on how to install a dog door in a screen door covers that job step by step.
And if your door is metal rather than wood, read can you put a dog door in a metal door before you cut.
Verdict: which dog door for a wooden door should you buy?
Buy the PetSafe Plastic Dog & Cat Door in the small size if you have a cat or small dog and a standard wooden door. It's the highest-scoring pick here because it fits the widest range of wood doors and comes with everything you need for a clean DIY install.
Pick the medium version for a dog up to 40 lb, or the large version for a dog up to 100 lb.
If your wooden door faces weather, choose the Baboni 3-Flap or the PetSafe Extreme Weather for their insulated three-flap seals. For a very large dog in a harsh climate, the Extreme Weather is the strongest choice.
And if you'd rather not cut the wooden door at all, the PetSafe Wall Entry door gives you a solid alternative in a wall.

Frequently asked questions
Can you put a dog door in a wooden door?
Yes. Most flap-style dog doors are designed for solid wood doors, and the kit includes a paper template so you can mark and cut the opening with a jigsaw.
Hollow-core doors and doors with glass panels are not suitable, so check the door's construction before you cut.
What thickness of wooden door works with a dog door?
It depends on the model. The PetSafe plastic doors fit doors from 1/16 in to 2 in thick, while the PetSafe Extreme Weather needs at least 1 1/2 in.
Measure your door's thickness at the spot where the flap will sit before ordering.
Do I need a special dog door for an exterior wooden door?
Exterior doors benefit from a door with insulation and a tight flap seal. Three-flap models like the Baboni or the PetSafe Extreme Weather block more drafts than a single flap, which matters in a climate with real winters or hot summers.
How do I stop my dog using the flap at night?
Use the closing panel that comes with most models. PetSafe includes a snap-on closing panel and the PetSafe Extreme Weather has a slide-in panel.
Petoasis adds locks on both the inside and outside for firmer control.
What size dog door do I need for my wooden door?
Measure your dog's chest width and shoulder height, then compare those numbers with the flap opening. Add a little margin so your dog can pass through without squeezing.
Small doors suit pets up to 15 lb, medium up to about 40 lb and large up to 100 lb.
