Best Dog Doors & Pet Doors: Buyer’s Guide & FAQ

What Is A Dog Door?

External household walls

The dog door product description provided by the manufacturer should tell you where you can install or mount the dog door.

How To Measure A Dog For A Dog Door

The dog door product description provided by the manufacturer should tell you how to measure the dog door for your dog. But in general you may measure by:

Measuring the width of the rib cage
Measuring from the floor to the top of your pet’s shoulders
Make sure the flap opening on the door is big enough for your pet based on these measurements

How To Install A Dog Door

The dog door manufacturer should tell you how to install the dog door and give you detailed instruction and a manual/guide on how do so.

Also, note that installing a regular door, wall, aluminum sliding door, electronic dog door and so on, all require slightly different requirements and considerations – which is why it’s so important to read the installation guide and instructions for specific factors to know. It may also pay to find YouTube or website videos showing you how to install the pet door.

But in general you may install by:

deciding whether you will do a DIY install or pay a professional to help you
planning where you will install the dog door and making sure you have everything in the existing area that you need to install the new dog door
For example, an electronic dog door may need a power outlet/source, a sliding dog door may need a big enough sliding door and certain bottom to top track height, a wall mount dog door may only fit in a certain thickness wall, and so on!
Get the dog door kit and make sure everything you need is in there like the door, frame, tunnel, hardware, cutout guide/template, weatherproofing strips and so on. Buy any additional hardware, sealant, timber packing and framing etc. that you need from a hardware store
Make sure you have the right tools for the install such as a cutting tool, a drill, a screwdriver (can be phillips head or sometimes a non standard screw is included in the kit so check this), and so on.
Measure and plan where and how you will install the dog door and at what height. You may need to mark it. Consider the height of your dog, the height of the lip of the dog door, and make sure you are installing the dog door at a height that is comfortable for your dog to walk through.
For regular dog doors you might cut out a section of the wall or door, insert and fix a frame or tunnel extender into the wall or door, and then fix the pet door onto the frame (and seal and weatherproof it).
For sliding door dog doors you may just need to snap and secure the dog door into the frame without cutting
Automatic dog doors may run on batteries, or need to be plugged into or hardwired into a power source
and so on for each type of dog door, and mounting location

Make sure you keep order documents and receipts, and read the warranty before and after installing the dog door in case there are any issues.

Training Your Dog To Use A Dog Door

Not all dogs are comfortable with using dog and pet doors straight away.

You may need to do some basic positive reinforcement and praise/treat training to encourage your dog to use the door.

A manufacturer should provide you with instructions on how to train your dog to use the door and get them familiar with it.
