Determine the proper height and width of your dog door pet flap opening by simulating pet door width and height at home. Do this with adhesive tape, tape measure, and an interior or exterior door.
Have your largest pet pass through an interior door that is open just wide enough for it to pass through. Measure that distance and choose a door pet flap opening slightly wider than that distance.
Wedge the door open to that inside width then place adhesive tape across the opening from the exterior door to door jam slightly higher than your dogs back to simulate the height of the pet flap opening.
Measure down the corresponding height of the pet flap opening and place a second piece of adhesive tape across the door to the jam at the bottom to simulate the bottom of the pet flap opening (refer to pet flap dimension size table to find correct dog door for your pet).
If your largest and smallest pet easily passes through the box you simulated you will verify the pet door size necessary and the installation height.
Doing this will help you determine what pet door size your pet requires and approximately where to install your pet door on your door.
