In this post, I provide a helpful guide on microchip pet doors and have reviewed the very best you can pick from. This is part of our series of guides on technology-enabled devices including the microchip pet feeders.
If you are a pet lover like me, you know just how tiring it can be to open and close the door for your dog or cat when he or she wants to get in and out of the house. Thanks to technology, we now have microchip pet doors that save us from operating a revolving door for our cats and pooches. Over the past years, pet products have seen tremendous revolution, and pet doors are not an exemption.
As we were growing up, our parents used traditional doggie doors which were small openings in our home walls or doors that were covered. Both dogs and cats would pass through this gateway to get into the house at will. However, they had their pitfalls which included letting in uninvited pets and not seal heat and cold. These microchip pet doors work by detecting the microchip installed in your dog or cat’s body. The door only opens and closes to the registered pet.
Today, I shall be looking into what microchip pet doors are, how to pick the best, as well as a review of doors for different dog sizes in the market. You will definitely find my article very engaging and helpful.

What is a microchip pet door?
This refers to the type of doors that detect the microchip inside your dog’s body to open only when your pet approaches to give them access in and out of the house. Unlike traditional doors, electronic doors help keep intruders out of the house which is an excellent safety measure. Microchip pet doors come in different types with some only opening after being activated by your pet’s microchip while others identify the sensors in his or her collar.
A microchip pet door comes in handy in giving your cat or dog the freedom of going in and out even when you are away from home. However, you will have to ensure that his backyard is safe and free of dangers by securing it with a fence. A physical fence is recommended if you want to keep your pet completely safe and prevent other animals from invading their personal space. This is especially important if you are using an electric fence.
While they save you from being your pet’s doorman, microchip pet doors are good for homes with multiple pets. In addition, your pets will have the freedom of potty breaks without having to wait for you to get home and allows them to be more active by exercising in your backyard. If you have a sick or senior pet in your home, they will not have trouble as the door automatically opens after detecting them. Did I mention that microchip pet doors are better than collar sensors? Yes, because if your pet loses his or her collar, they will not get into the house.
How to pick the best microchip door
Now that you have learned about these handy devices and their benefits, the next step is to buy it for your pet. So, here are 8 things you should look for in a microchip pet door.
- Size of Opening
You should buy a microchip pet door that is compatible with your dog or cat’s size. If you have a home with multiple pets, you should consider a door that matches the largest pooch at home. So, make sure that you measure your dog’s size at the shoulders for the height then add 2” to 3”. Read and use the manufacturer’s instructions.
- Build Material
Go for a door that is constructed using high-quality materials if you want something that lasts. From stainless steel to plastic, the build material is an important factor. In addition, look at the door’s aesthetics to make sure that it has an excellent appearance. To regulate heat and cold, choose a microchip pet door with an airtight seal.
- Set Up
After measuring the door’s size, do the same to the position where you plan to install it to make sure that it is a good fit. As mentioned earlier, read the company’s manual for fixing guidelines before making the first cut. Most microchip pet door manufacturers include a template for testing if the size is a perfect fit which is easier to install. Some doors, however, will require you to hire a pro.
- Detection System
Choose a microchip pet door that only opens when your dog or cat walks towards it, not when he or she comes near it. This keeps your home secure from intruding people and pets who may take advantage of the opening. If you have multiple pets at home, make sure that the door is designed to identify more than one chip.
- Access Control
Although microchip pet doors open by recognizing your pet’s installed microchip, others come with higher-tech that allows you to access them via a smartphone app. This allows you to control your pet’s door remotely so you can keep your pets in case of terrible weather conditions. They can even be programmed to a schedule that specifically opens and closes the door at your own will.
- Quietness
Pick a door with a liner that prevents it from making irritating sounds when opening and closing. This discreteness not only gives you good sleep but also keeps your pet’s in and out moments private.
- Monitoring Feature
Some microchip pet doors come with a special feature that allows you to monitor your cat or dog’s activities. Your vet can use this information to check the activities and come up with a schedule that locks the pet in when you need him inside.
- Power Source
From rechargeable batteries to replaceable ones, microchip pet doors come with different sources of power to choose from. Whichever you find best, make sure that the batteries are always in good shape

Microchip Pet Door for Medium and Large Dogs
Dog size descriptions vary greatly in definition among pros and dog owners. Medium dogs, however, are considered to have a weight of between 20 and 60 pounds with a height range of between 8 and 27 inches at the shoulders. Examples of medium-sized dogs include beagles, American Staffordshire, Australian cattle dogs, border collie, and more.
A large dog, on the other hand, has a weight of at least 50 pounds but under 100 pounds with a height of approx. 24 inches at the shoulders. Some examples include the English Mastiff, Newfoundland, Leonberger, Bernese Mountain Dog, Chinook, and more.
Here are my 3 best microchip pet doors for your medium and large dogs:

Microchip Pet Door for Sliding Glass
Your dog or cat will love to look through the glass and enjoy the view of the backyard or neighborhood from the house. And while that is enjoyable, the feeling of being locked inside without the ability to access what they see outside can be frustrating. That is where a pet door for sliding glass comes in handy. Check out my 3 top options.
Best for Dogs: Ideal Pets Vinyl Sliding Door Dog Door
Size: 12¼” x 16” Large panel, 8¼” x 12” Medium panel
Recommended Weight: 91 to 120 pounds
Material: Aluminum

At the top of my list in the sliding glass doors for dogs is this great product from Ideal Pets. It is made with aluminum material for sturdiness and a great finish that complements your vinyl patio door. The Vinyl Sliding Door for Dog Door is lightweight with great perfection when it comes to designing it into your most preferred shape. But as the name suggests, it is specifically made for use in vinyl doors only.
This pet door features an extra-large flap that measures about 10” x 15” made from tempered glass to help match perfectly with your glass sliding door. The vertical height of this dog door frame measures 76” x 78”. As you can see, the tempered glass makes it ideal especially for your large dog as it can endure its energetic build and weight.
One tip as you buy this product is to confirm whether you are purchasing the double-pane VIP or the single-pane VPP. I know it sounds insignificant, but it determines the build quality and cost.
Pros:
- Specifically made for vinyl patio doors
- Adjustable height by 2” for perfection
- Lightweight & durable
- Double-pane glass frame
Cons:

Best for Cats: Patio Pacific Vinyl Dog Door for Sliding
Size: 22¾” to 25¾” Windows
Material: Aluminum
Layout: Vertical

This product from Patio Pacific is an excellent choice if your French windows slide sideways rather than down. The Vinyl Dog Door for Sliding may have the name ‘dog’ pinned to it, but I found it to be best suited as a cat door that works great with vertical sliding windows. However, it can be a good option for small dogs as well.
The pet door features an aluminum frame that slides into the designed area using a spring-loaded mechanism. When installing this pet door, you must ensure that it measures more than 1” in thickness for it to fit perfectly. I love the versatile aluminum and spring load housing which allows the metal sash to be adjusted up to 37” in width. The door’s flap is lightweight which makes it easy for your cat, pup, or small dog to push through without a hassle.
As you would expect from a product of its quality, this pet door can withstand severe weather and is corrosion-free for durability and reliability. Patio Pacific offers pro installation services, and you can reach them via a toll-free number for help that is provided in their products.
Pros:
- Durable & reliable construction
- Suitable for cats & small dogs
- Customized to fit in vertical sliding windows
- Spring-loaded fastener
Cons:
- Not for homes with medium or large dogs
- Some people say big cats have problems getting in or out

Examples of extra-large dog breeds include Doberman, German Shepherd, Golden Retriever, Labrador, and more.

In addition, it is fitted with a Lockout slide that works with a spring to help keep your pet out of trouble when away from home.
