A made-to-order pet door with replaceable service parts, multiple frame colors and configurations for a more precise, lasting fit.
Choose your size →Greyhounds often need more vertical clearance than width, making the tall intermediate openings especially useful to compare.
Choose the installation model first, then verify pet size, rough opening, frame dimensions, finish and flap package.

Choose your size →Measure the high shoulders and narrow body independently so the dog receives height without an unnecessarily broad frame.
Keep step-over and flap resistance manageable, especially for retired racers, senior dogs or animals still building confidence in a new home.
Compare tall intermediate openings for a Greyhound’s high shoulders and relatively narrow body.
Shopping Dog Doors for Greyhounds begins with proportions, not a weight bracket. Dogs of similar weight can have very different shoulder height, chest width and leg length. The 11-size system includes tall versions that add vertical clearance without automatically adding width, plus wider XL and Giant choices for broad animals. Compare actual clear openings and watch the animal’s natural gait. The goal is a passage that does not demand a deep crouch, shoulder compression or a jump over an unnecessarily high lower edge.
Measure height and width independently so the dog receives vertical clearance without an unnecessarily broad frame.
Take each measurement at least twice. Use the widest body point for horizontal clearance and the top of the shoulders for vertical planning; the head may dip naturally, but the back should not scrape the frame. Establish step-over by considering leg length, age and mobility. For two or more pets, the largest animal controls minimum width and height while the smallest or least mobile animal often controls mounting height. Breed charts are a starting reference only, especially for mixed breeds and dogs outside typical ranges.
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.
Set a manageable lower edge and check that the taller outer frame fits the planned surface.
Once a flap size looks comfortable, stop and check the building dimensions. Larger openings need larger rough cuts and frames, and tall sizes may run into glass, door rails, wall framing or screen crossbars. Tape the full frame outline in the planned position and look at both sides. Confirm the selected model is offered in that size and finish. If no standard option balances animal comfort with available structure, move the location or evaluate a verified custom configuration rather than forcing a near fit.
Use lower resistance and gradual training for retired racers, seniors or dogs still building confidence.
Sizing affects daily performance for the life of the opening. An undersized door can encourage crouching, hesitation or contact with the frame. A greatly oversized opening may increase unnecessary air movement and demand more mounting space. Watch the first training sessions for rubbing, awkward stepping or difficulty pushing the flap package. Keep the lower route clear and inspect flap edges because a pet that repeatedly contacts one side may reveal an alignment or sizing problem worth correcting early.
Do not choose a wide XL size when the measured need is primarily height or force a low-confidence dog through two flaps immediately.
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.
Save the pet measurements that drove the decision along with the selected flap size, mounting height, step-over, rough opening and full frame. For a growing dog, note the age and expected adult range; for a multi-pet home, record which animal controlled width, height and lower-edge placement. Recheck fit if mobility changes. These notes make it easier to decide later whether a behavior problem is training, flap wear, mounting height or a genuine need for a different opening.
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.
