Step 1: 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.

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 the Doggie Door

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