1. PlexiDor Performance PDE Electronic Pet Door

The first product on our list is the PlexiDor Performance PDE electronic pet door, designed for both dogs and cats.

Manufactured in the US, it comes with a waterproof collar “key” that weighs less than an ounce, and the best part is that it does not need any batteries to function. It snaps onto your dog’s collar to do the job, the sensor within the door detecting that it is indeed your specific pup, allowing them in and out of the home. Furthermore, this door is also child- and puppy-safe, so will not close if the doorway is obstructed.

This door’s programming system is simple for most users, letting you add or change thousands of codes with one-touch programming. You can set the timing for how long you want the door to stay open as well as any other time-related features for safety. It also does not interfere with underground fences or home security systems, either.

Buying Guide: Best Dog Doors with Sensors

While all the above dog doors have been carefully selected to meet a variety of needs, you may need to narrow down your search further. Read on to find some of the key features you need to consider before picking the perfect one.

1. Key Fobs

Most smart dog doors come with a key fob that you can attach to your dog’s collar to signal the door to open and close. The door will not open for any other animals that do not have the sensor attached to them in some way, so this guarantees that you get freedom from any unwanted guests entering the home.

For pet owners with more than one dog, each pet must wear a collar with a key fob for the system to work perfectly. The key fobs do a flawless job unless your pet loses their collar or the fob is lost due to some other reason.

2. Microchip Access

For pets who are microchipped, you may purchase a pet door that can be synced up with your pet’s implanted microchip. You will need to program the door to open and shut for the specific microchip in your cat or dog or even sync it up to multiple microchips if you have more than one pet in the house.

3. Insulated Flaps

Another amazing feature of these pet doors is the insulated flaps that keep drafts from getting into your home. These protective flaps do a good job of saving you from wasting any energy by preventing air from passing through them. We suggest that you choose the doors that come with gasket seals for the best protection from undesired airflow or even adverse weather conditions.

4. Lock Modes and Curfew Timers

Modern-day dog doors are much more advanced than you might imagine. These high-tech doors now come with curfew timers and lock modes so that they open up only at certain times of the day and stay locked for certain hours, all of which will be specifically decided by you. Some doors will let your pet come in but not allow him to go outside when set to certain lock modes.

This feature comes in handy if your dog has the habit of going out and barking at a certain time of the night. With curfews and special lock modes, you can decide when he is allowed to step out.

5. Apps

Some dog doors can be synced with apps allowing you to operate them by using the app even if you aren’t home. Some even have monitoring features to let you keep track of an ill pet while you’re away. You can keep track of when and how often your dog goes out even when you are not in the home to watch him or her.

Related Questions

Do dog doors make the house cold in winter?

No. They do just the opposite. When you do not have to open the main doors of your home several times a day to let your dog in and out, less heat escapes from the home. With these secure flaps, the heat stays inside and your home stays warmer, and this saves energy as well.

Can other animals like rats and snakes come through dog doors?

No. As the products reviewed above use sensors, they only allow a pet wearing a collar with the sensor keys on it to enter through the dog door. The flap will not open and allow other animals access to the home, so this gives you peace of mind.
