Buying Guide

Pet Size

Size is essential when buying a door for your dog. The height of the door should be tall enough for your dog to pass through comfortably. It also shouldn’t be too wide or too narrow. If it’s too narrow, your dog may not fit, but if it’s too wide, it could be easier for cold air or possibly wild animals to get in. For best results, measure your dog’s height and width and choose a door that’s slightly bigger. Some companies have a size chart available.


Most dog doors include a safety lock. A locking feature is important since it allows you to lock the door when you don’t want your pets using it. Locking it can ensure your dog is safe inside. Many dog parents also keep it locked at night or when they’re not home to prevent wild animals and burglars from getting in.

Door Type

There are several kinds of dog doors available. Some are built into walls, some are installed in doors, and some work with sliding doors. You will have to decide where you want to install the door and then purchase the correct type. All types can be high quality, but they won’t be effective if they can’t install where you want them to.
