 Best Electronic Dog Door For Multiple Pets: Buying Guide

Different dog breeds will have different sizes and needs, so it’s important to choose an electronic pet door that can accommodate multiple pets of varying sizes. If you have more than one pet, a smart pet door for multiple animals will make it easier for all of them to have access to the outdoors.

Large dogs may have difficulty fitting through a standard-sized sliding door. Whether you have cement walls or a sliding door, a smart pet door can be installed to accommodate their size and provide convenient access.

With many outstanding and remarkable smart dog doors available, it can be hard to determine which is best for you. Here are the things you have to consider when buying a smart dog door:

How Is It Set Off?

Electronic dog doors can be set off by either an external device attached to the dog’s collar or by an integrated microchip.

You may choose a microchip-activated dog door if your pet does not wear a collar, while a collar tag is a good choice for bigger canines, as a microchip-activated dog door is likely to be available in a small size.

A high-tech dog door can be set up in a window, wall, or door. Different variations are on hand. It depends on where you want to set it up.

Power Source

Electronic dog doors can be battery or mains-operated, so research which would be the most cost-effective and energy-efficient for you. Find a pet door that you can connect to your existing electrical system, or choose a model that runs on batteries for more flexibility in placement.


This is a vital factor to think of when making a purchase. There is a big difference in price between different styles and brands.

Smart key

As a pet owner, you want to keep your pooch safe and secure. A smart key or microchip would allow you to restrict wild animals from accessing certain areas of your home or property. Additionally, a smart fob can also help monitor your pet’s movement, and only the pets with the collar keys would have access to your property.

What to Look For In Electronic Dog Doors?

Dog owners should look for electronic dog doors that are durable and weatherproof, as they will be exposed to the elements. It is also important to consider the size of the door, ensuring it is suitable for your dog’s breed and size.

Additionally, features such as adjustable settings for different access modes and programmable timers can provide added convenience and security. Here are some features to look for:

Size dog door

There’s no standard size for a dog door. Each dog is exceptional and has its size or measurements. For this reason, measure your canine prior to choosing the dog door panel size.

You should ensure that your fur friend can move in and out with ease. If you’re getting one for a puppy, you should factor in extra allowances for development.

Access Control

This feature assists in determining how the electronic dog doors open and how your four-legged friend utilizes the automatic door. For instance, you can avoid entry from outside if the dog is inside your house. Find an automatic pet door that comes with two pde collar keys if you own more than one dog.

Ease of Installation

If the electronic dog door installation is an easy process, it’s more beneficial than spending an extra buck on a handyman to do the task. Check on the difficulty in setting up the smart dog door. You should be able to install some pet doors within a few minutes and others in less than an hour.

Directional Sensing System

The lack of a well-defined directional sensing system will unlock each time the dog is close by. It is extremely recommended to buy a smart dog door with a precise sensing system because this will prevent the swing door from accidentally opening when the dog walks past.


Search for a long-lasting or durable material like steel that has an extra aesthetic value as well. A steel security plate will provide the necessary strength and protection for the automatic door.

Energy Efficiency

Each time the dog door opens and closes, you lose a bit of thermal energy. Add them all up for more than months, and your bills will go up to a greater extent. The electronic dog door should be energy efficient and have the right sealings to make sure minimal heat loss.

How Do Electronic Dog Doors Work?

Automatic dog doors work by using sensors to detect when the dog is approaching. These sensors can be activated by a special collar worn by the dog or by motion sensors that detect movement. Once the sensors are triggered, the door automatically opens, allowing the dog to pass through.

Some electronic dog doors also have programmable settings that allow you to control when and how the door opens, providing added convenience and security. You can control how long the door remains open and adjust the sensitivity of the door to prevent any unwanted intrusions.

When getting these pet doors, you want to ensure that you get one that has an airtight seal. This will help to keep out drafts and maintain the temperature inside your home. Other pet owners like it when the flap automatically locks once your furry friend is out of a specific range.

Can Pet Doors Prevent Other Animals From Entering Your Home?

Yes, pet doors can help prevent other animals from entering your home. Many pet doors come with features such as magnetic or electronic locking systems that only allow access to pets wearing a specific collar or tag.

This ensures that only your own pets can enter and exit through the door, keeping out any unwanted intruders. The door remains fully locked until a pet wearing the specific tag approaches it. Lastly, these pet doors allow you to keep your child and dog child safe from stray animals without compromising security.
