Dog Doors for Glass

Treat an in-glass dog door as a glass-fabrication project, not a homeowner field cut. A glass professional must identify the panel and determine the correct fabrication path. The defining question for Dog Doors for Glass 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 give the glass professional the model-specific cutout and frame information. Pet measurements and glass fabrication dimensions answer different questions and both must be correct. Check the clear flap opening for the pet, the rough opening for the cut and the tip-to-tip frame for the available mounting area.

Tempered and insulated glass cannot simply be cut in place. The professional may need to fabricate a replacement panel with the prepared opening and install the in-glass frame as part of that work. The exact product instructions and selected SKU should be available before any permanent opening is made.

A permanent in-glass installation preserves a clean integrated opening when specified correctly. Flap count, frame finish, magnet alignment and future replacement parts remain configurable ownership decisions. Record the model and size, keep moving surfaces clean and replace only verified compatible service parts.

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.

Use the custom-size workflow after checking the standard size chart. Enter whether the measurement is based on flap opening, rough opening or outer frame so the order and installer are working from the same dimensions.

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.
