Give Spot his own pet door

It seems some dogs always want to be on the other side of the door. When they’re out, they want in. When they are in, they want out. But it doesn’t have to be a problem. Just give Spot his own door, and he can come and go as he pleases, and you won’t have to serve as a doggie doorman. It’s a fairly easy project.

Installing a pet door was a recent topic on The Home Depot community forums, brought up by community member txdan07, who admits to be being a bit of a novice when it comes to DIY projects.

txdan07 wanted advice on installing a pet door in a garage door without cracking the garage door’s bottom metal guard.

Forum associate HDAnswerman offered up step-by-step instructions.

1. Gather materials – electric or cordless drill, drill bits, a jig saw and jig saw blades.

2. Mark the location on the garage door where you want the pet door to be located, using the template supplied with the doggie door as a guide.

3. Draw an outline of the opening on the door. The directions will specify the size of the opening required.

4. Drill four holes in the garage door – one at each corner of the doggie door opening. Use a 3/8 inch or 1/2 inch drill bit. You will need to insert a jig saw blade in the holes.

5. Select the proper jig saw blade. If the door is metal or plastic use a metal cutting blade. If the door panels are made of wood or a wood composite, use a wood cutting blade.

6. Cut. Follow the lines you drew on the door to complete the cut. Go slowly to assure a good clean cut.

7. Install the pet door using the directions included in the package.

  1. I have an existing dog door but want to install a more energy efficient door. taking the old one out looks like a matter or unscrewing a few screws. Measurements on the cut our area is H 17″ x W 10 1/2″. The old door of course has different measurements. Please advise on installation of new door and model if known. Thank you
