Don't just go out and buy an electronic dog door without knowing your dog's size first. Plus, if you have several dogs, you should always go off your largest dog's size to give you an idea.

To help give you a better idea of your dog's size, you should measure from one shoulder to the other to provide you with an idea of the width of the door. Then from the ground to the shoulders to help give you an idea of your dog's height.

If you want ones that can handle different types of weather, you may wish to opt for a stainless-steel door instead of a plastic one. Similarly, if you want ones that don't let much cold or heat into your home, you will want to purchase an electronic dog door with an air-tight container.

What to consider when buying a door?

When looking to buy an electronic door, you should consider the following:

  • Noise: Some electronic dog doors can be incredibly noisy and cause a lot of disturbance. You might want to choose a dog door with a liner that causes less sound to be produced. This will help save you sleep, especially in the morning or late at night when your dog needs to go outside.
