Sizing and Fit
Are all configured pet doors returnable like stock items?+
Do not assume so. Review the current policy for made-to-order and custom products before submitting the configuration.
Are these pet doors made to order?+
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.
Can an old dog learn to use a dog door?+
Many can, but mobility, vision, confidence, step-over and flap resistance need extra attention. Use short, low-pressure sessions.
Can common wear parts be replaced?+
Compatible flaps, magnets, weather strip, covers, locks and other service parts are available when matched to the exact model and size.
Can I buy an automatic dog door from Dog Doors Depot now?+
Yes. Verified door-mount, wall-mount and low-e patio configurations are available with exact 2026 SKU pricing. Select the opening size and installation type on the product page before checkout.
Can I order a replacement flap from the old flap measurement alone?+
Use the original model and named size when possible because worn flexible material can change dimensions.
Can I order an automatic dog door today?+
Yes. Door-mount, wall-mount and low-e patio configurations are available with exact 2026 SKU pricing. Select the model, opening size and panel height shown on the product page before adding it to the cart.
Can I replace the flaps later?+
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.
Can I use the adult breed size for a puppy?+
Expected adult size can guide planning, but growth is uncertain. Confirm likely adult measurements and make sure the present mounting height remains manageable during training.
Can I use the sizing quiz before ordering aluminum dog doors?+
Yes. The sizing quiz is a useful starting point because it asks for the pet, opening type, size and weather conditions before pointing you toward a model family.
Can I use the sizing quiz before ordering automatic dog doors for large dogs?+
Yes. The sizing quiz is a useful starting point because it asks for the pet, opening type, size and weather conditions before pointing you toward a model family.
Can I use the sizing quiz before ordering automatic dog doors for sliding glass doors?+
Yes. The sizing quiz is a useful starting point because it asks for the pet, opening type, size and weather conditions before pointing you toward a model family.
Installation Surfaces
Can a dog door go in a hollow-core door?+
Only when the selected model and preparation support that construction. Inspect the core and plan any required blocking or self-framing details before cutting.
Can a screen pet door go in a security door?+
Do not treat an ordinary screen model as a security-door product. Verify the actual assembly and its requirements.
Can an automatic dog door go in a wall?+
Only use a wall-compatible model and tunnel system. Verify the complete wall depth, structure, utilities, exterior water management, housing clearance and power route.
Can an existing tempered panel be cut?+
Generally no. A qualified glass professional normally prepares a compatible replacement panel with the opening created during fabrication.
Can I cut a fire-rated door?+
Do not alter a rated assembly without written approval from the authority and people responsible for that door.
Can I install an in-glass dog door myself?+
In-glass work requires a qualified glass professional and may require a replacement fabricated panel. Do not field-cut tempered or insulated glass.
Can the in-glass cutout use wall-model dimensions?+
No. In-glass work uses its dedicated product and fabrication information and should be reviewed by a qualified glass professional.
Can the mesh support a dog door by itself?+
No. Use the frame, retainer and stabilizer arrangement intended for the selected screen model and placement.
Do automatic dog doors require a special collar?+
Some use a pet-worn transmitter or tag, while other activation methods may be offered. Check the selected model and plan replacement devices or batteries for every authorized pet.
Do these automatic dog doors open for the pet?+
Yes. Power Pet models use a motorized panel activated by a recognized ultrasonic collar; they do not merely unlock a flap. Directional sensing helps the panel respond to a pet approaching the opening.
Does exterior caulk replace flashing?+
No. Water management may require compatible flashing, slope and drainage as well as perimeter sealant.
How often should I inspect an exterior dog door?+
Inspect it during routine home maintenance and after severe exposure. High-use or weather-exposed openings may need more frequent checks.
Weather and Insulation
How often should exterior seals be checked?+
Include them in seasonal maintenance and inspect after severe weather or visible movement.
Why does a clean flap still stay open?+
Check magnet and strike alignment, weather strip, frame squareness and whether the flap has curled or stiffened.
Why does a flap stay open?+
Check debris, curled vinyl, magnets, strikes, weather strip and frame squareness before assuming the flap alone is the problem.
Security and Covers
Are all catalog items covered by the same manufacturing and warranty claims?+
Check the exact product specification and current written warranty. Do not extend a core-model statement to every accessory without verification.
Does the frame warranty automatically include labor and shipping?+
Do not assume so. Review the current written warranty for coverage, exclusions and required documentation.
Replacement Parts
Should I discard a failed part before contacting support?+
No. Photograph it in place and retain it until the request instructions say otherwise.
What is the difference between a flap and a complete kit?+
A flap-only order replaces the flexible panel; a complete kit may include additional service components. Check the exact product contents.
Why do the apparent holes on a new flap not match?+
Some marks may be top-bar rivets rather than screw holes. Follow the replacement instructions and use verified pilot-hole locations.
Ordering, Shipping and Returns
Should I cut the opening while a return question is pending?+
No. Keep the product and building unmodified until compatibility and return instructions are clear.
What should a return request include?+
Include order number, exact item, reason, condition, photographs and any required authorization information.
Where are current policy answers?+
Use the dedicated warranty, shipping and returns pages and keep the exact order record with any request.
