Choosing a Dog Door Size

Dog Door Sizing We recommend the "Cardboard Test" to ensure the correct size for your pet. Using the OPENING SIZE measurement in the charts, cut a hole in a piece of cardboard, and see if your pet can pass through easily.

The test can also be done by wedging open a house door to the OPENING WIDTH, and block off the OPENING HEIGHT (starting just above your pet's shoulder) and call your pet through. Pets duck their heads as they push open their door and step through it, so ideally you should install the pet door with the top of the opening just above your pet's shoulder. Any position will do as long as your pet can open the door and get through comfortably.
