8 Best Locking Dog Doors for Walls (November 2026)
The best locking dog doors for wall mounting include the ClawJaw Steel Large Dog Door for Exterior for most homes, the ALUMANI Dog Door for Wall for a half-open setting, and the Baboni Telescoping Wall Pet Door for medium dogs.
On this page (5 sections)
The best dog door for wall mount with lock is the ClawJaw Steel Large Dog Door for Exterior, which pairs a sliding lock panel with a steel frame and double flaps. Pick the ALUMANI for its three lock positions, the Baboni for a medium dog, or the PlexiDor when your wall is thicker than 8 in.
A wall-mounted door gives your dog its own way in and out without cutting into a sliding glass door or a nice entry door. The lock is the part that matters most after dark: a panel you slide shut turns the opening from a pet route into a closed wall.
The models below all share one thing: a closing panel or lock you control from inside. They differ in frame metal, flap count, wall range and dog size.
That spread is what this guide sorts out. If you want the wider field first, our roundup of the best wall dog doors covers siding, stucco and brick fits.
Our score weighs specs, features and buyer feedback against what you're shopping for.

The best locking dog doors for walls, ranked
ClawJaw leads because its steel build and lock panel cover the most homes and the largest dogs. The rest of the list fills gaps: a half-open setting, a medium frame, a thick-wall fit and cold-climate insulation.
ClawJaw Steel Large Dog Door for Exterior: Best for most homes
- Alloy steel frame and telescoping tunnel
- Double flaps and sliding lock panels
- Fits walls 3 9/10 to 7 7/8 in thick
- Flap opening 14 1/3 x 10 in
A steel frame and a lock panel you slide shut, sized for big dogs and a wide range of wall thicknesses.
Pros
- Steel frame and tunnel
- Sliding lock panel
- Double flaps
- Wide 3.9–7.88 in wall fit
Cons
- Heaviest build here
- Largest frame at 21 2/3 x 14 in
ClawJaw suits the average household with a big dog and a standard exterior wall. The frame and telescoping tunnel are alloy steel, so the door holds its shape against daily barging.
Its flap opening is 14 1/3 x 10 in, and the frame measures 21 2/3 x 14 in. That opening takes dogs up to 110 lb, which covers most Labs, shepherds and mixed large breeds.
The lock is a sliding panel, and the two flaps close on magnets behind it. ClawJaw says the double flap and panel together cut drafts and protect against extreme weather.
The tunnel adjusts from 3 9/10 to 7 7/8 in, so it fits common stud and masonry walls alike. The instructions include templates, which matters on a thick wall where a sloppy cut is hard to fix.
The trade-off is weight and size. A steel frame this big needs a sturdy mounting surface, and the cut-out is larger than the medium picks here.
It also costs more than the aluminum VOSOIR models.
Buy it if you want the strongest all-round lock and a big dog fit. Skip it for a small dog or a very thin wall.
ALUMANI Dog Door for Wall: Best for a half-open setting
- Alloy steel frame with polished edges
- Two sliding panels with three modes
- Two self-closing magnetic flaps
- Fits walls 3.94 to 7.88 in thick
Twin sliding panels give you open, closed and half-open settings, so the dog can come and go but not wander far.
Pros
- Three lock positions
- Rust-proofed steel frame
- Magnetic self-closing flaps
- Cutting template included
Cons
- 100 lb limit is lower than the top pick
- Coffee color only
ALUMANI is the pick when you want to limit how far the dog roams. Its two sliding panels give three modes: fully open, fully closed and half-open.
The half-open setting leaves a gap big enough for the dog but short of a full opening.
The frame is alloy steel with polished edges and rust-proofing, so it holds up in damp conditions. Two self-closing magnetic flaps seal behind the pet, and ALUMANI says the dense top strips and magnets keep out dust, insects and cold air.
It fits walls from 3 15/16 to 7 7/8 in thick, including stucco, wood and brick. A cutting template and guide come in the box.
The coffee finish is calmer than black if the door sits on a painted exterior wall, and the smooth edges matter if a dog brushes the frame on the way through.
Against the ClawJaw, you give up a little pet weight (100 lb versus 110 lb) and gain the half-open mode. The steel frame is close in strength.
Buy it if the dog should not wander the yard all day. Skip it if you want the widest dog fit or a black finish.
Baboni Telescoping Wall Pet Door, 3-Flap Medium: Best for medium dogs
- Three-flap design with magnetic seals
- Steel frame and aluminum lock
- Flap opening 8 1/4 x 12 1/4 in
- Fits walls 4 3/4 to 7 1/4 in thick
A triple flap keeps out more drafts than a double, in a smaller frame for dogs up to 40 lb.
Pros
- Three-flap draft block
- Metal closing panel
- Cut-out template and screws included
- Lighter frame
Cons
- 40 lb limit
- Narrower 4.75–7.25 in wall fit
Baboni is the medium-dog answer. Its flap opening is 8 1/4 x 12 1/4 in, and the frame is 12 1/4 x 17 1/8 in, sized for pets up to 40 lb.
A beagle, a corgi or a small terrier fits; a Lab does not. The cut-out in the wall is 9 7/8 x 13 3/4 in, smaller than the large doors here.
The three-flap design is the reason to pick it. Three layers of flap seal out drafts and weather better than two, and Baboni says the triple layer keeps the house shielded from extreme weather.
The bottom magnet holds the flap shut.
The frame is metal with a laser-welded build and an aluminum lock. A metal closing panel comes with it, so you can lock the opening when the dog is inside.
The telescoping tunnel takes walls 4 3/4 to 7 1/4 in thick, a narrower range than the large models here.
Against the big steel doors, this one gives up size and wall range. In return it is lighter to fit and easier to lift into place on a ladder.
Buy it for a medium dog and a wall in the 4.75–7.25 in range. Skip it if your dog is over 40 lb.
VOSOIR Dog Door for Wall: Best for large dogs on a budget
- All aluminum alloy frame
- Double magnetic flaps
- Closing panel with dual-side aluminum locks
- Fits walls 3.95 to 7.5 in thick
A full aluminum build with locks on both sides of the closing panel, for dogs up to 110 lb.
Pros
- All-aluminum frame
- Locks on both sides
- Quick-release flaps
- Spare flap support
Cons
- Two flaps instead of three
- No insulation layer
VOSOIR's large door is the budget route to a 110 lb fit. The frame is full aluminum alloy, which VOSOIR says resists rust and warping better than iron or plastic.
The flap opening is 18.7 x 9.92 in and the wall cut-out is 10.6 x 18.9 in.
The lock is the draw: a closing panel with aluminum locks on both sides. When locked from inside, the panel cannot be opened from outside.
That matters if the door faces a street or an alley.
Two magnetic flaps with dust-proof furring strips seal the opening. The flaps are quick-release, so you can pull one off to clean it or swap it.
VOSOIR says it replaces damaged flaps free, which cuts long-term upkeep. The lighter aluminum body also means one person can hold it in place while the other drives screws.
The tunnel fits walls 3.95 to 7.5 in thick. Against the ClawJaw, you lose the steel frame and one flap layer.
In return you get a lighter door that is easier to install alone.
Buy it if you want dual-side locks and a big flap opening without paying steel-frame prices. Skip it if your winters are harsh enough to want a third flap.
VOSOIR Dog Door for Wall: Best for UV blocking
- All aluminum alloy frame
- Translucent PA flap panel that blocks UV
- Closing panel with dual-side aluminum locks
- Fits walls 3.95 to 7.5 in thick
The flap panel cuts UV and insulates better than standard baffles, according to VOSOIR, with locks on both sides.
Pros
- UV-blocking flap panel
- Locks on both sides
- Quick-release flaps
- Spare flap support
Cons
- Two flaps only
- Same lock design as the other VOSOIR
This second VOSOIR is the same lock and frame package with one twist: the flap panel. It is a translucent PA material with a brown and black tint that VOSOIR says blocks UV rays.
It also insulates hot or cold air 50% better than traditional baffles, according to the brand.
That matters for a door on a sunny west wall or one that faces a cold wind. The translucent panel lets light through, so a dog facing the flap can see the yard on the other side instead of a dark sheet.
The flap opening and tunnel range match the other VOSOIR at 18.7 x 9.92 in and 3.95 to 7.5 in.
The closing panel and dual-side aluminum locks work the same way: lock from inside and the panel stays shut from outside. The kit also includes screws, instructions, a cutting template and a spare flap.
Against the standard VOSOIR, the only real difference is the flap material. Against the ClawJaw, it is lighter and easier to fit but has one less flap layer.
Buy it if UV and glare through the flap bother you. Skip it if you want the plainest, cheapest large lock door.
PlexiDor Performance Wall-Mount Pet Door: Best for thick walls
- Aluminum frame with saloon-style panels
- Solid steel security plate
- Fits walls up to 12 in thick
- Flap opening about 11 3/4 x 16 in
A steel security plate and a 12 in wall range make this the pick for deep walls and extra security.
Pros
- Fits walls up to 12 in
- Steel security plate
- Saloon-style panels
- PlexiDor backs it with a warranty
Cons
- Highest cost tier here
- No telescoping tunnel
PlexiDor is the pick for a thick wall. It fits walls up to 12 in deep, well past the 7.88 in ceiling of the steel and aluminum models here.
A stone, double-brick or insulated wall is where it earns its place.
The frame is aluminum with saloon-style panels that swing in both directions. The lock is a solid steel security plate, heavier than the slide-in panels on the other doors.
PlexiDor says the plate adds protection when the door is not in use. The whole unit weighs 17.4 lb, so plan for help when you lift it into the opening.
The flap opening is about 11 3/4 x 16 in, and the door suits pets up to 100 lb. PlexiDor backs it with a 10-year warranty and makes it in the USA.
The trade-offs are cost and fit. It sits in the highest price tier here and needs a wider wall opening than the telescoping models.
It also has no telescoping tunnel, so the depth has to be right before you cut.
Buy it for a thick wall or a door you want to lock with a steel plate. Skip it for a standard 4–8 in stud wall where a telescoping door costs less.
VOSOIR 3-Flap Insulated Aluminum Wall Dog Door, Large: Best for cold climates
- Three flaps with an added insulation layer
- All aluminum alloy frame
- Closing panel with locks on both sides
- Fits walls 3.95 to 7.5 in thick
The triple flap and extra insulation layer block more cold air than the two-flap VOSOIR models.
Pros
- Three-flap insulated build
- Locks on both sides
- Fur strips and strong magnet seal
- Spare flap support
Cons
- Thicker flap stack than the two-flap version
- Heavier than the standard VOSOIR
The three-flap VOSOIR is for cold climates. It adds a thermal insulation layer and new insulation material on top of the double flap, so the seal blocks more cold and hot air than the two-flap models.
Fur strips on the sides and a strong bottom magnet finish the seal.
The rest of the package matches the other VOSOIR doors: full aluminum frame, a closing panel with aluminum locks on both sides, and a flap opening of 18.7 x 9.92 in for dogs up to 110 lb. The tunnel fits walls 3.95 to 7.5 in.
VOSOIR also offers a replacement flap for when the original wears out.
The third flap makes the door thicker and slightly heavier, and it costs more than the two-flap version. That is the real trade-off: better weather sealing for a little more money and weight.
Buy it if your door faces winter wind or a hot summer sun and you want the tighter seal. Skip it if you live in a mild climate and want the cheaper two-flap door.
PETCOMING 3-Flap Insulated Aluminum Wall Dog Door: Best for weather extremes
- Three flaps with a thermal insulation layer
- All aluminum alloy frame
- Dual security locks and a removable closing panel
- Fits walls 3.95 to 7.5 in thick
Built for hot and cold swings, with three flaps, a thermal layer and two locks on the closing panel.
Pros
- Three-flap insulation
- Dual security locks
- Firefighter stickers included
- Spare flap support
Cons
- Lowest score in this group
- White frame only
PETCOMING closes the list with a three-flap insulated aluminum door built for weather swings. The triple-flap system blocks cold drafts, heat and wind, and the added thermal layer keeps the indoor temperature steadier.
The kit lists three interchangeable flaps for year-round use.
It also packs two security locks and a removable closing panel. The panel keeps unwanted animals out and the house secure at night or when you travel.
Two firefighter stickers come in the box to alert rescuers in an emergency.
The size and fit mirror the other large models: an 18.7 x 9.92 in flap for pets up to 110 lb and a tunnel for walls 3.95 to 7.5 in. Screws, instructions and a cutting template are included.
The brand also offers replacement flaps and parts through its store.
Its score is the lowest here, which comes down to a white-only finish and fewer distinct features than the VOSOIR three-flap door. The lock and insulation are still solid.
Buy it if you want the firefighter stickers and dual locks in one kit. Skip it if you want a color choice or the top-rated insulation build.
How these locking dog doors compare

The comparison table lines up frame metal, wall thickness range and pet weight for every door. Use it to rule out models before you read the full write-ups.
The wall range is the first thing to check. A telescoping tunnel covers a spread of thicknesses, so measure your wall at the door location and pick a model whose range contains that number.
Steel frames run heavier and stronger; aluminum frames run lighter and easier to fit alone.
The lock type splits into two families. Most doors here use a slide-in closing panel with locks on one or both sides.
The PlexiDor uses a solid steel security plate. Both stop the dog and slow a person; neither replaces a locked house door.
Flap count is the third axis. Two flaps handle most homes, three flaps seal better against wind and heat, and a thermal layer in the middle of the stack adds another step.
Price tracks all three: steel and three-flap insulated doors sit at the top of this group.
How we compared these locking wall dog doors
We started from the models that ship with a closing panel or lock, then sorted by how well each fits a typical exterior wall. Frame metal, wall thickness range, flap count and dog weight came from the product data.
From there we weighed the lock design. Dual-side locks score higher than a single panel, and a steel security plate scores higher still for security.
We also counted the flap layers, because three flaps seal better than two in wind and cold.
Finally we looked at fit. A door that covers more wall thicknesses helps more readers, and a size spread from 40 lb to 110 lb lets us match each dog to a door.
That mix set the scores you see, from 9.2 down to 7.2.
What should you check before you buy a locking dog door?
Start with the wall itself. Measure the thickness at the exact spot where the door will go, because a tunnel that is too short leaves a gap and one that is too long will not seat.
Then measure your dog's shoulder height and chest width against the flap opening, not just its weight.
Which lock type should you choose?
A slide-in closing panel is the easiest to live with. It stores flat against the door when open and slides into a track when you lock up.
Dual-side aluminum locks mean the panel cannot be opened from outside when locked from inside.
A steel security plate is heavier and harder to shift. Pick it when the wall faces a street or you want the strongest barrier.
For a step-by-step routine, our guide on how to lock a dog door covers panels, plates and night-time habits.
What frame material holds up best?
Steel is the strongest frame in this group. ClawJaw and ALUMANI both use alloy steel and fit walls up to 7.88 in.
It costs more and weighs more, so fitting one alone on a ladder is harder.
Aluminum is lighter and resists rust without paint. VOSOIR, Baboni and PETCOMING use aluminum or a mix.
It suits a door you plan to install yourself and a climate where damp is a concern. PlexiDor pairs an aluminum frame with a steel plate for security.
How many flaps do you need?
Two flaps are enough for most homes. They close on magnets and keep out most drafts.
Three flaps add a middle layer and, on the insulated models, a thermal layer that blocks more cold and heat.
Choose three flaps if the door faces winter wind, a hot afternoon sun or a noisy road. The extra layer also muffles sound a little.
The cost is a slightly thicker, heavier door.
Can you fit a locking dog door in a brick wall?
Yes. A telescoping tunnel made for 3.95 to 7.88 in walls covers most single-skin brick.
The cut needs a core drill or a mason, and the lock panel must still be reachable from inside the house. Our post on whether you can put a dog door in a brick wall walks through the cutting and sealing steps.
What size door fits a large dog?
Large models here use a flap opening of about 14 1/3 x 10 in or 18.7 x 9.92 in and suit dogs up to 110 lb. Measure the dog standing, from floor to the top of the shoulders, then add a little room for a collar or harness.
The flap width needs to clear the chest at its widest point. A door that is too tight makes the dog push through and wear the flap edges.
A door that is too wide leaves a gap for drafts and small animals.
Which locking wall dog door should you buy?
Buy the ClawJaw Steel Large Dog Door for Exterior if you want the best lock, frame and dog fit in one door. Choose the ALUMANI for its half-open setting, the Baboni for a dog under 40 lb, or the PlexiDor if your wall is thicker than 8 in.
For a cold wall, the three-flap VOSOIR or PETCOMING is the tighter seal.
If you are still weighing wall styles and sizes, start with the pet door overview and match the opening to your dog before you order. Measure the wall twice, pick a lock you will actually use every night, and the rest of the install follows.

Frequently asked questions
What is the best dog door for wall mount with lock?
The ClawJaw Steel Large Dog Door for Exterior is the best overall, with a sliding lock panel, double flaps and a steel frame that fits walls from 3.9 to 7.88 in thick. The ALUMANI is the closest runner-up if you want a half-open setting.
Do locking wall dog doors really keep intruders out?
A closing panel with locks on both sides makes the opening hard to push through from outside. It still only secures the flap, not the wall around it.
Lock the panel at night and when the house is empty, and treat it as one layer of home security.
How thick can a wall be for a locking dog door?
Most telescoping models here fit walls from about 3.95 to 7.88 in thick. The PlexiDor Performance Wall-Mount Pet Door goes further, with a fit for walls up to 12 in.
Measure the wall at the exact spot before you order.
What size dog door do I need for a large dog?
Large models here use a flap opening around 14 1/3 x 10 in or 18.7 x 9.92 in and suit dogs up to 110 lb. Measure your dog's shoulder height and chest width, then compare both with the flap opening, not just the weight limit.
How do I lock a dog door when I leave the house?
Slide the closing panel into its track and turn the locks on the inside. When locked from inside, the panel cannot be opened from outside on the dual-lock models.
Store the panel somewhere you can reach it quickly when you get home.
