Wall-mounted dog doors create a dedicated route without occupying an exterior door. Choose the model by finished wall depth, pet size and exposure.
Choose the installation model first, then verify pet size, rough opening, frame dimensions, finish and flap package.

A durable, weather-sealed pet door engineered for a secure through-wall installation and available in a wide range of sizes.
Choose your size →Three wall-depth families cover thin assemblies, common walls and deep masonry or specialty construction. Each configuration pairs the interior and exterior frame with the correct tunnel depth.
Measure the complete finished wall—not just one layer—and check for wiring, plumbing and structure before cutting. Flashing and rain protection accessories help manage exposed locations.
Choose the wall model by the complete finished wall depth, not just the visible drywall or masonry layer. Thin, standard and deep-wall families use different tunnel ranges.
The defining question for Dog Doors for Walls is what the frame will pass through and what must remain functional around it. A flap opening is only the pet passage; the installed frame occupies more room and may interact with structural members, door rails, glass edges, screen frames, locks, trim and weather seals. Compare the product’s rough opening and outer dimensions with a drawing or taped outline on both faces of the proposed location. If the outline crosses hardware, uneven panels or required edge clearances, change the location or model before ordering.
Size the pet first, then verify that the corresponding rough opening and full frame fit between framing, utilities and exterior constraints at the proposed height.
Separate animal fit from construction fit. First choose a clear opening that lets the pet pass with modest clearance at the shoulders and sides. Next translate that choice into the exact rough opening and tip-to-tip frame for the selected model. Finally confirm mounting height and step-over. This sequence matters because two frames with the same flap size can have different exterior requirements, and the easiest location for a contractor may not be the easiest height for the animal.
Dog Doors Depot carries 11 standard flap sizes from Small Medium through Giant, including tall intermediate sizes that separate height from width. Use the individual animal rather than the label as the decision-maker. After the clear opening is selected, compare the exact product variant because model families can use different frame, tunnel and cutout relationships. If every standard choice creates a meaningful compromise, use the custom-size workflow and keep the submitted dimensional basis attached to the order.
A wall opening can involve studs, wiring, plumbing, sheathing, insulation, flashing, cladding and interior finish. Investigate the assembly before ordering and use an experienced installer when conditions are uncertain.
Read the model-specific manual before layout, not after the opening is cut. Verify tools, fasteners, sealants, tunnel pieces, frame orientation and any professional trade requirements. Check for utilities and structural conditions in walls; internal reinforcement and ratings in doors; support and mesh condition in screens; and fabrication requirements in glass. Protect finished surfaces and control dust or metal filings. After fastening, test that the original door, screen or panel still operates and that both pet-door flaps move without rubbing.
A square tunnel, intact weather components and correct exterior water management help the flaps close and the wall remain serviceable after the cutout is complete.
Surface choice changes maintenance. Exterior walls and doors need periodic perimeter and water-management inspection. Screens need mesh tension and frame support checks. Glass installations should be watched for seal or panel issues by the appropriate trade. Every configuration benefits from clean magnets, flexible flaps, unobstructed cover tracks and a recorded model and size. When a flap no longer lies flat or a magnet misses its strike, correct the component or alignment before the gap becomes the normal operating condition.
Do not use the flap dimensions as the wall cut dimensions and do not select a tunnel depth until the entire finished assembly has been measured.
A strong preflight is deliberately repetitive: measure again, check the dimensional label, compare both faces of the opening and read the exact manual. Confirm that the host door, wall, screen, glass or kennel panel remains safe and functional after the cutout. Record uncertainty instead of converting it into a guess. If structure, utilities, ratings, glass type or water management are unclear, pause the product decision and have the appropriate installer or trade verify the condition. That short review is less expensive than correcting an incompatible made-to-order frame.
Move from shortlist to order only after four checks agree. The pet fits the clear opening; the building can accept the rough opening and full frame; the selected model matches the surface and thickness; and the flap, finish, cover and accessory choices match the intended use. Save the product page and model instructions with a labeled measurement sheet. For multiple openings, give each location its own ID and configuration. Review every line before submitting because made-to-order dimensions and options should not be inferred from another opening or corrected after fabrication begins.
Read the finished configuration back as a complete sentence before approving it: model family, named size or custom dimensions, measurement basis, frame finish, flap count, installation surface, finished thickness and mounting location. Then compare that sentence with the cart, worksheet and installer scope. This catches a correct measurement attached to the wrong model or a correct product attached to the wrong opening. When two pets share the door, confirm the widest body, tallest shoulder and lowest comfortable step-over still work together. Photograph the taped frame outline and keep that image with the order so the installer can verify placement before cutting.
Document the material and finished thickness the frame passes through, plus any tunnel pieces, flashing, compensation strips, stabilizers or fabricated glass information used in the installation. Photograph both faces and note the sealants and finish work completed. Surface details are easy to forget once the frame is in place, yet they matter when a leak, alignment issue or future renovation is investigated. A clear record helps the next repair preserve the original water, structural and operating assumptions.
Before submitting a made-to-order request, make sure the saved measurements tell one clear story: which pet was measured, what each dimension represents, where the door will be installed, and which options were selected. If the project requires a contractor or glass professional, keep that person’s verified construction dimensions beside the pet measurements so neither set is mistaken for the other. A complete record makes the order easier to confirm now and makes future flap, cover, lock or weather-strip service much easier.
Keep the measurement sheet, exact product page and installation manual together through ordering and installation.

Measure from the floor to the top of your pet’s shoulders and measure the widest point of the body. The flap should generally sit about 1–2 inches above the shoulders, with a comfortable step-over height. Use the actual pet measurements rather than breed averages.
Yes. Frame color, flap count, size and installation type are selected for your opening. Review the measurements and selected configuration carefully before submitting an order.
Yes. Replacement flaps, flap kits, magnets, weather stripping, locks and covers are available. Match the replacement part to the original pet-door size and model.
