What the AI looks for in Dog Doors
- Flap height
- Top of the flap opening should sit at least an inch or two above the dog's shoulder (withers) height Dogs that have to duck repeatedly strain their backs and may refuse the door.
- Flap width
- Opening wider than the widest part of the dog, usually the chest or hips A tight fit makes the frame rub, and the dog stops using it.
- Step-over height
- Bottom of the opening low enough for the dog to step over comfortably; for seniors and short-legged breeds keep it low A high sill is a tripping and jumping hazard.
- Installation surface
- Match the kit to the surface: door, wall (needs a tunnel the depth of the wall), or sliding/sash insert Wall installs need a tunnel kit, and door kits don't fit glass.
- Seal and flap
- Prefer magnetic or weighted flaps that close fully, and double flaps in cold climates Most energy loss and complaints come from flaps that hang open or blow in.
- Security
- A lockable closing panel is the minimum Large flaps can admit wildlife or intruders.
Brands that matter
- Endura Flap: Weather-resistant flexible flaps; door, wall and window models.
- PetSafe: Widest range of door, patio and weather models.
- Hale Pet Door: Heavy-duty door and wall models aimed at long service life.
- Ideal Pet Products: Ruff-Weather and patio-insert doors.
What to avoid
- Sizing by dog weight alone instead of measuring height and width
- Single thin vinyl flaps in cold or windy climates
- Very large flaps without a locking cover in homes concerned about security
Questions
Should I size for my puppy or the adult dog?
Size for the adult dog. A puppy can use a larger flap, but you cannot enlarge a cut-out later without re-cutting.
