9 Best Wall Dog Doors for Siding, Stucco and Brick (October 2026)
The best wall dog doors include the Baboni Telescoping Wall Pet Door for large dogs and three flaps, the PetSafe Wall Entry Telescoping Pet Door for a plastic frame, and the Baboni Telescoping Wall Pet Door for medium dogs.
On this page (5 sections)
The best dog door for a wall depends on your pet's size and the finished wall thickness. The Baboni 3-Flap Large is the top pick for larger dogs, while PetSafe offers a plastic frame and small option for cats and smaller dogs.
A wall tunnel can give you more placement choices than cutting into a door, but the opening crosses the whole wall assembly. Measure the pet, check the tunnel range, and plan how the frame will meet the exterior finish.
If you're still weighing wall, door and patio options, start with how to choose a dog door. For a wall made of brick, see whether a dog door can go in a brick wall before deciding where to cut.

Which wall dog door fits each pet and wall?
The Baboni large and medium models cover common dog sizes, while PetSafe adds a small opening and a PVC frame. The other picks offer different flap designs, larger pet capacities or wider wall thickness ranges.
Baboni Telescoping Wall Pet Door, 3-Flap Large: Best for large dogs and three flaps
- 10 1/4 x 16 1/4 in flap opening
- For pets up to 100 lb
- Telescoping tunnel fits 4 3/4–7 1/4 in walls
- Metal closing panel
A large opening, three flaps and a telescoping tunnel make this a strong fit for many exterior wall installs. Check the wall cutout dimensions before buying.
Pros
- Three-flap design
- Telescoping tunnel for common wall thicknesses
- Metal closing panel
Cons
- Wall thickness range is limited to 4 3/4–7 1/4 in
- Requires a 12 x 17 3/4 in wall cutout
The Baboni large is the leading choice for a large dog when the wall is 4 3/4–7 1/4 in thick. Its 10 1/4 x 16 1/4 in flap opening is sized for pets up to 100 lb, and the required cutout is 12 x 17 3/4 in.
It uses three flaps and has a metal closing panel. Measure your pet's height and width against the opening, since weight alone doesn't show whether your dog can pass through comfortably.
The tunnel range is a key limit: thicker walls need a different solution or additional planning. Check the full finished wall thickness at the exact opening, including cladding and interior layers.
Choose it for a large pet and a wall within its tunnel range. Read our wall dog door installation guide for brick if masonry is part of the project.
PetSafe Wall Entry Telescoping Pet Door, Large: Best for a plastic frame
- 10 1/4 x 16 1/4 in flap opening
- For dogs up to 100 lb
- Telescoping tunnel fits 4 3/4–7 1/4 in walls
- Double flap and slide-in closing panel
The plastic PVC frame is designed not to rust, and the double flap and closing panel add weather protection. A compatible extension kit is sold separately for thicker walls.
Pros
- Plastic frame won't rust
- Tunnel fits 4 3/4–7 1/4 in walls
- Closing panel slides in
Cons
- Extension kit needed for walls thicker than 7 1/4 in
- Double-flap design
PetSafe's large model has the same 10 1/4 x 16 1/4 in flap opening and a 4 3/4–7 1/4 in tunnel range. The PVC frame won't rust, and its double flap pairs with a slide-in closing panel.
For a wall thicker than 7 1/4 in, PetSafe says a compatible extension kit is sold separately. Check that the kit fits your wall and the planned opening before cutting.
This pick suits buyers who prefer a plastic frame and need a large opening. The flap design is double-layered, so compare it with the three-flap option if you want another flap layer.
Baboni Telescoping Wall Pet Door, 3-Flap Medium: Best for medium dogs
- 8 1/4 x 12 1/4 in flap opening
- For pets up to 40 lb
- Telescoping tunnel fits 4 3/4–7 1/4 in walls
- Metal closing panel
This three-flap medium option has an 8 1/4 x 12 1/4 in opening for pets up to 40 lb. Measure the pet's widest and tallest points to check fit.
Pros
- Three-flap design
- Medium opening for pets up to 40 lb
- Metal closing panel
Cons
- Requires a 9 7/8 x 13 3/4 in wall cutout
- Tunnel fits walls up to 7 1/4 in
The Baboni medium reduces the opening to 8 1/4 x 12 1/4 in and is designed for pets up to 40 lb. Its three-flap design and metal closing panel match the large Baboni's approach in a smaller size.
The required wall cutout is 9 7/8 x 13 3/4 in, and its telescoping tunnel fits walls 4 3/4–7 1/4 in thick. Don't use weight capacity as the only sizing check; a broad-chested dog may need more opening width.
Choose this size when your pet fits the opening and your wall falls within range. For measuring steps, use our guide to measuring your dog and wall opening.
PetSafe Wall Entry Telescoping Pet Door, Small: Best for cats and small dogs
- 5 1/4 x 8 1/8 in flap opening
- For pets up to 15 lb
- Telescoping tunnel fits 4 3/4–7 1/4 in walls
- Double flap and slide-in closing panel
A small opening suits cats and small dogs up to 15 lb. The PVC frame and slide-in closing panel are useful details if rust resistance and control matter.
Pros
- Small opening for cats and small dogs
- PVC frame won't rust
- Closing panel adds extra insulation
Cons
- May be too small for many dogs
- Extension kit needed for walls thicker than 7 1/4 in
The PetSafe small opening measures 5 1/4 x 8 1/8 in and is intended for cats or dogs up to 15 lb. Its PVC frame, double flap and slide-in closing panel make it a compact option for a smaller pet.
Like the large PetSafe, its tunnel fits 4 3/4–7 1/4 in walls, with a compatible extension kit sold separately for thicker walls. Confirm the opening against your pet's measurements before settling on this size.
Baboni Double-Flap Wall Pet Door, up to 40 lb: Best for a double-flap medium door
- 8 1/4 x 12 1/4 in flap opening
- For pets up to 40 lb
- Telescoping tunnel fits 4 3/4–7 1/4 in walls
- Metal closing panel
The double-flap design is an alternative to the three-flap medium pick. Its metal frame and telescoping tunnel suit walls within its stated thickness range.
Pros
- Double-flap design
- Telescoping tunnel fits 4 3/4–7 1/4 in walls
- Metal closing panel
Cons
- Requires a 9 7/8 x 13 3/4 in wall cutout
- No three-flap layer
Baboni's double-flap medium door has an 8 1/4 x 12 1/4 in opening for pets up to 40 lb. Its tunnel accommodates walls 4 3/4–7 1/4 in thick, and its required cutout is 9 7/8 x 13 3/4 in.
Choose this model if you want a double flap rather than the three-flap medium design above. It also has a metal closing panel, which lets you block the opening when needed.
Petoasis 3-Flap Heavy-Duty Wall Dog Door: Best for a thicker tunnel range
- Three flaps with insulation layer
- Aluminum alloy frame
- Fits walls up to 7.9 in thick
- Flaps can be removed separately
Its stated wall thickness limit reaches 7.9 in, slightly beyond several picks here. The three flaps include an insulation layer, and each can be removed separately for a dog that needs an easier passage.
Pros
- Fits walls up to 7.9 in thick
- Three flaps with insulation layer
- Flaps can be removed separately
Cons
- No minimum wall thickness supplied
- Flap opening dimensions not supplied
Petoasis states that its aluminum alloy frame fits walls up to 7.9 in thick, giving it the widest stated upper limit among these picks. Its three flaps include an insulation layer, and the maker says the flaps can be removed separately for pets that need an easier passage.
The available details don't give a minimum wall thickness or the flap opening dimensions. Confirm both before choosing it, especially if your dog is near the stated opening size for another model.
MIAOTONG 3-Flap Never Rust Wall Dog Door, X-Large: Best for extra-large dogs
- 13 1/8 x 24 7/8 in flap opening
- For pets up to 220 lb
- Fits walls 3 9/16–6 11/16 in thick
- Aluminum frame
The extra-large opening and 220 lb capacity suit very large pets. Its wall thickness range differs from the other top picks, so check your wall before choosing it.
Pros
- Largest stated weight capacity here
- Extra-large opening
- Brush seals
Cons
- Maximum wall thickness is 6 11/16 in
- Large wall cutout needs careful planning
MIAOTONG is the extra-large choice for pets up to 220 lb, with a 13 1/8 x 24 7/8 in flap opening. It fits walls 3 9/16–6 11/16 in thick and includes brush seals.
That wall range starts thinner and ends sooner than several other options here. Check the full wall thickness and make sure the large cutout works with the home's structure before choosing this size.
Decormax Heavy Duty Wall Dog Door, Large: Best for walls 4–8 in thick
- Fits walls 4–8 in thick
- For dogs under 110 lb
- 11 x 16 1/2 in flap opening
- Two sliding lock panels
This aluminum door fits walls up to 8 in thick and has two sliding lock panels. Confirm its 11 x 16 1/2 in opening and cutout needs against your wall and pet.
Pros
- Fits walls 4–8 in thick
- Two sliding lock panels
- Magnetic flap bottom
Cons
- Double-flap design
- No cutout dimensions supplied
Decormax fits walls 4–8 in thick and is designed for dogs under 110 lb. Its aluminum frame has two sliding lock panels, and the flap opening measures 11 x 16 1/2 in.
The cutout dimensions aren't specified here, so confirm them before marking the wall. Its double-flap design may suit buyers who want an opening for a large dog with two lock panels.
PETCOMING 3-Flap Insulated Aluminum Wall Dog Door: Best for a 3.95–7.5 in wall
- Fits walls 3.95–7.5 in thick
- For pets up to 110 lb
- 18.7 x 9.92 in flap opening
- Dual security locks and closing panel
The three-flap design and aluminum frame pair with a wall range starting at 3.95 in. Check the opening orientation and your dog's measurements before cutting.
Pros
- Three flaps
- Fits walls 3.95–7.5 in thick
- Dual security locks and closing panel
Cons
- Opening dimensions should be checked for fit
- Cutout dimensions not supplied
PETCOMING gives a wall thickness range of 3.95–7.5 in and a capacity of up to 110 lb. The aluminum frame, three flaps, dual locks and removable closing panel make it a feature-rich option for a large pet.
Its stated flap opening is 18.7 x 9.92 in. Check which measurement is width and which is height, then compare both with your dog's standing measurements and the wall cutout plan.
What should you check before cutting siding, stucco or brick?
Check the wall thickness, framing and opening dimensions before cutting through any exterior finish. A tunnel that fits the wall still needs a properly planned cutout and a sealed connection to the surrounding materials.
Measure the finished wall at the intended location. Siding, sheathing, insulation and interior drywall all affect the tunnel length, and the listed tunnel range must include the full thickness.
Then locate studs, pipes and wiring. A cutout that overlaps framing or hidden services can turn a simple pet door project into a larger repair, so inspect both sides of the wall and use a suitable detection tool.
The exterior surface changes the work. Siding and stucco need a clean perimeter and weather seal, while brick can require masonry tools and extra care around the opening; our brick wall installation guide covers that case.
How do you choose the right tunnel and flap size?
Choose a tunnel whose stated range includes the full finished wall thickness, then select an opening your pet can use without squeezing. The cutout size is larger than the flap opening, so use the model's cutout measurement when marking the wall.
Measure your dog's widest point while standing and the height from the floor to the top of the back. Compare those measurements with the flap opening, then account for growth or mobility needs where relevant.
For example, Baboni's medium opening is 8 1/4 x 12 1/4 in and the large is 10 1/4 x 16 1/4 in. PetSafe's small opening is 5 1/4 x 8 1/8 in, so it is aimed at cats and smaller dogs.
If your pet is close to the opening dimensions, consider a larger size only after confirming the required wall cutout fits the planned spot. Our dog door sizing guide explains the measurements to take first.
Are three flaps better for an exterior wall?
Three flaps add another layer, and some models also describe an insulation layer, but flap count alone doesn't guarantee a draft-free opening. Fit, flap closure and the seal around the wall frame all affect how air can move.
The Baboni three-flap models include a metal closing panel, while PetSafe uses a double flap and slide-in panel. Petoasis describes an insulation layer within its three-flap design, and PETCOMING also uses three flaps.
Think about how often your dog uses the door and how you plan to close it when not in use. For more ways to manage drafts, read how to stop cold air coming through a dog door.
Which wall dog door should you choose?
Choose the Baboni 3-Flap Large for a large dog if your wall is 4 3/4–7 1/4 in thick and its 10 1/4 x 16 1/4 in opening fits your pet. Pick the PetSafe Large for a similar opening with a PVC frame, or the PetSafe Small for a cat or small dog.
For a medium dog, compare the two Baboni medium options by flap count. For a thicker wall, Petoasis, Decormax or PETCOMING may fit their stated ranges, while MIAOTONG is the extra-large pick for its 220 lb capacity.
Before you cut, verify the wall thickness, pet measurements, cutout size and the route through framing. See our guide to choosing a dog door to compare wall tunnels with other installation types.

Frequently asked questions
Can you install a dog door in siding, stucco or brick?
Yes, a wall dog door can work in siding, stucco or brick, but the installation steps depend on the wall construction. Plan the cut through the finished surface and interior wall, and check for wiring, pipes and framing before cutting.
Brick may need masonry tools and careful sealing.
Read our guide to putting a dog door in a brick wall before choosing a spot.
How do you size a wall dog door?
Measure your dog standing up at the widest part of the chest or abdomen and from the floor to the top of the back. Compare those measurements with the flap opening, then check the maker's weight guidance.
Also confirm the wall cutout dimensions and tunnel range.
Our dog door measuring guide walks through the measurements.
How thick can a wall dog door tunnel fit?
It depends on the model. Several picks here fit walls 4 3/4–7 1/4 in thick, while Petoasis states a limit of 7.9 in and PETCOMING gives a 3.95–7.5 in range.
Measure the finished wall at the planned opening, including siding or other layers, and choose a tunnel that covers that thickness.
Do three flaps help keep drafts out?
Three flaps add another layer between indoors and outdoors, and some models include an insulation layer. That design may help limit drafts, but it doesn't guarantee an airtight seal.
For any wall opening, careful installation and sealing around the frame matter too.
See our guide to keeping cold air out of a dog door.
