Step 1

remove the door from hinges

Prepare the Door

Remove your door from its hinges. This is usually a two-person job.

Consider the height of your pet and the height of the door and mark on the door where the doggie door will be placed.

Pro Tip

Big dogs need big doors. Measure the shoulder-height of your pooch and make sure to choose a doggie door that's big enough to accommodate your dog.

Step 2

Drill and Dry Fit Your Doggie Door

Drill holes in the 4 corners of the door (Image 1) and cut out the door using a hand-held circular saw.

Dry fit the doggie door to your cut hole (Image 2).

Raised panel doors may require fill pieces to support the door (Image 3).

Step 3

attach front and back of doggie door together

Attach the Doggie Door

Screw the front side and the backside of the doggie door together.

Step 4

Reattach the Garage Door

Reattach the big door on its hinges.

Once the door has been installed, it's time for the final test. Have your dog do a test run. He should comfortably fit through the door.
