Best Dog Door for Sliding Glass Door Buyer’s Guide
If you’re still confused about what to look for in the best sliding dog door, we’ve organized the important features and created a quick list for you to go through. We’ll break down the different types of doors to the materials and installation. If you didn’t find your dream sliding glass doors for dogs on our top list, you can definitely find the best one with this guide.
A sliding glass pet door can be broken down into different categories. The different types are defined by your dog’s access. They fit into four main categories: Microchip, RFID, ultrasonic and magnetic dog doors.
In our humble opinion, microchip dog door options are the best choice. This is because it does away with the collar which not all dogs wear at all times. But we can almost guarantee that all house dogs have a microchip. A microchip is different than a collar because it doesn’t only have your dog’s identification, but it has your information as well. In some cases, a microchip can even be used to locate your dog. But in this case, it’s used to open doors.
There is no need for batteries and configurations if you use a microchip detecting dog doors. Another best feature of a microchip sliding pet door is it will automatically keep out pests and animal intruders. The pet door won’t open in the absence of a microchip and become a security precaution.
RFID doors incorporate the use of electromagnetic frequencies that are emitted from key tags. RFID stands for “radio frequency identification”. Manufacturers will most likely include an RFID tag that has the correct information stored on it and corresponds to the patio panel dog doors. Of course, the doors won’t open without the correct RFID signal and these devices also do not require batteries.
Ultrasonic sliding glass dog doors will require a collar. Ultrasonic sound waves are not detectable by the human ear but can be heard by your dog. But don’t worry, you can adjust the sensitivity levels so even though they are audible for your dog, they won’t be irritating. However, keep in mind that the sensitivity settings may also affect the distance at which your dog will be registered by the door. Ultrasonic collars require batteries to operate and definitely come in the form of collars. However, they are durable, mostly lightweight and weatherproof.
Magnetic dog doors are exactly what they sound like, a pet door that operates with the principles of magnets. The door itself doesn’t require batteries or power to run but the magnetic collar key will. Magnetic dog door flaps have a very obvious drawback, and that is it does not recognize the difference between an intruder and your pet.
It’s tougher to purchase a sliding glass dog door because you need to take into account the size of your dog and your door. With two factors to think about, it greatly limits your options on the market. You might have your eye on the perfect sliding glass dog door but the flap is too small to accommodate your pooch. Much like getting a crate, you need to measure your dog accurately to ensure the compatibility of the pet door. The size of the opening should be your first consideration.
Since your dog will bend as necessary to go through the pet doors, the general rule of thumb is to look for a pet door that is a couple of inches higher than your dog’s shoulders. This will provide sufficient room for him when he ducks through. As for the width, the same rule applies. About 2 inches on either side would give your dog enough leeway without scraping himself. Also, keep in mind that puppies will grow, so it’s necessary to make the calculations based on his projected full-grown size.
The material of the dog door is imperative to its durability. Most dog doors, whether it’s for sliding glass doors, wooden doors or aluminum frames are made from either plastic or aluminum. You might think that aluminum is sturdier than plastic, but in reality, they are both pretty tough. The biggest difference between the two materials is longevity. Due to its properties, aluminum doors tend to outlast plastic ones and become a more permanent fixture in your home.
When you have the heater or air conditioner on with your window or door open, you can just imagine the energy loss and the hit your utility bill will take. Some pet owners have a bit of trepidation when it comes to a doggie door and the installation process fearing it will run up their electrical bill. Fortunately, you can make sure this doesn’t happen and preserve energy efficiency with the perfect seal and construction of the doggie door.
There are options that advertise themselves as insulated pet doors and they tend to fit your sliding glass screen door tightly. The tighter the seal, the less chance the outside air has to get in. There are also some alterations you can do to the seal to make it more secure. However, this might come at the expense of the overall appearance of the sliding glass door.
We are all about installation and setup when it comes to buying a product, and the same goes for dog doors. Don’t go for a pet door that requires tools to assemble and the installation of different components – that’s just way too much work. There are very easy sliding glass pet doors that are fitted onto your aluminum patio door frame for a seamless and tight fit and are very easy to install.
Safety and Lock
The flap size isn’t the only thing to remember when it comes to the safety of the sliding door. A microchip pet door may be easy to use, but is it safe? The best sliding door comes with some sort of locking mechanism to keep your dog inside when the situation calls for it. The lock will work with any patio panel door and should be easy to install. You may also find a magnetic closure for some sliding doors that will seal the flap tightly with the polarity of the magnets.
There are also ones that come with a slide-in closing panel. It serves as a block for your sliding glass dog doors and it also doesn’t affect the door installation.
Benefits of a Sliding Glass Dog Door
A pet door isn’t just an opening inserted into your sliding door frame for your dog to enter or exit out of. There are so many benefits to having this option. Whether you have a traditional vinyl flap or a high-end automatic microchip pet door such as ones from Petsafe Freedom Aluminum Pet Door or Endura Flap, they will only improve your dog’s lifestyle.
It’s not just humans who like freedom, dogs appreciate it too! Giving your dog the ability to enter and exit whenever he wishes instills trust between the two of you. This is especially true for dogs that are potty trained to go outside. The best dog doors will have a magnetic closure or something that’s just as sturdy but will give way when your dog needs to do his business. You won’t need to take time out of your day to let him out and he won’t need to hold it any longer when he can simply exit whenever he wants.
If you have a well-trained pup, it also gives him the flexibility to go exploring, wandering and playing in your yard whenever he chooses. What’s good about these sliding glass dog door installations is the locking mechanism. If at any time you want to keep your pooch confined indoors, just implement the security locks.
As dog owners, we all know boredom, anxiety, extra energy, and basically every feeling under the sun can get your dog to act up. A lack of exercise will cause extra energy buildup in your pooch, which could lead to destructive behavior. You need to make sure you take him out for a walk or two a day depending on the breed, but some of us just don’t have that time. This is when a pet door is extremely convenient. He can take himself out for a walk or run around the yard and expend his excess energy.
If he’s bored and ran out of things to do, the corner of your couch or your patio panel will look inviting and fun to chew. While this may be his new favorite pastime, it can quickly become your worst nightmare. A sliding glass door for your pooch at this time will give him extra entertainment when he explores your yard.
With anxiety, we would actually recommend keeping an eye on him with a doggy cam rather than letting him out if you aren’t home. Dogs with separation anxiety can be quite the escape artists, so if you give them access to the outside, he may just run after you.
As we said, a doggy door isn’t only a great addition for a dog, but for you as well. Imagine the convenience it affords you of not having to keep track of when to let your fur baby out with an automatic pet door. You can keep to your own schedule without having to consider him too much. He can also pretty much walk himself within the confines of your property with the right pet door.
Preserve Your Door
Having a glass door that’s easy to install will save you the headache of having to retouch your door frames. A dog that’s bored, has to go, wants to go outside can be quite rambunctious. Dogs are known to chew but also to scratch up a storm. This is when your poor door might take the full brunt of it. After a few months or years, it definitely won’t last. This is when an extra-large, extra small, or anything in between glass door for dogs can come in handy.
How Do I Install the Best Sliding Glass Door for My Dog?
As we said, the installation is easy as we can see with Petsafe Freedom Aluminum Pet Doors and the ones from Endura Flap. Check to see if any tools are needed and if so, assemble everything you need right away. If not, there are a lot of sliding glass door designs that simply snap onto your sliding door frame and automatically have a tight seal. You need to make sure the sliding door for your pet is secure, and you can do this by giving it a strong wiggle or two.
How Do I Train My Dog to Use a Doggy Door?
Just like with other things, training your dog takes a lot of patience, positive reinforcement and time. One of the most important things to be sure of when teaching your dog how to use the best pet door is to convey what you want clearly. Your pooch can be sitting there confused, not knowing what to do and disobey your commands not because he is stubborn.
The flap can be confusing for your dog, so let’s secure it in an open positive for now. If you have an automatic door, check to see if there is an “always open” option. This is when having a family member help out is a good idea. Since he is your dog and logically will be more attached to you, you should be the one on the other side of the door and the family member is on the inside with your fur baby. Make sure you have lots of treats to entice him.
When in position, call out to your dog and see what he does. Most pooches are quite smart and in his attempt to get to you he will figure out he can pass through the sliding door flap. If he doesn’t get it yet don’t worry, it just takes a few more tries. When he eventually makes it to the other side, praise him with plenty of his favorite treats and belly rubs. When he’s ready, reverse the process with you on the inside and your pooch and family member outside. Once he’s got the hang of it, have your family member leave and see how well he does on his own.
Don’t try to go from introducing the door to non-stop entering and exiting in one day. Give your dog a break, as we are sure you need one too, and try again the next day. If he performed flawlessly after a few tries, you can lower the flap. The best doggy door options out there may be automatic, so you can lower the flap now. Then keep practicing with the flap down. If he doesn’t necessarily get it right away it’s okay! Just lift the flap up again and try again.
Eventually, your pooch will get the hang of it and the dog door will be pretty much the best investment you’ve made all year.
Frequently Asked Questions
Can a dog door be installed in a sliding glass door?
The dog door won’t be installed in the door but actually next to the door in an open position. Installation shouldn’t be too difficult and there are plenty of options on the market that is a snap and fit design. The door comes with all the necessary parts for installation and maybe even a magnetic closure for safety.
Do buglars use dog doors?
This depends on many factors. For one thing, the burglar needs to be desperate enough to crawl through the little opening. The flap size will also affect how successful the burglar is at getting in.

Are dog doors a bad idea?
No, dog doors are not a bad idea. In fact, they are an awesome idea for the reasons we mentioned above including the convenience, freedom and flexibility it affords you and your pooch. The only thing to be aware of is the compatibility the dog door has with your sliding glass door and the installation process.
What is the most secure dog door?
There are a lot of answers including all the ones on our list, but another one of the most secure dog doors would be the Watchdog Steel Security Pet Door. Just from the name alone, you can guess the sturdy construction and security the dog door provides. It has a 4-digit combination lock and is made from 12-gauge steel.

For the more daring pet parents, you can even attempt to create your own door. Whichever one you decide on, we’re sure will be the best choice for your dog.
Did You Know?
While nothing is really as convenient as a doggie door, there are some next best options you can consider including dog doorbells, potty training indoors with pee pads and grass pads, and dog fences. What will work best also depends on your lifestyle. If your dog is trained to go indoors and out, then a doggy door may not be necessary since he can go on his walks and on the pee pad when he’s home.
It was touched upon briefly, but it’s very important to make sure you get the right size by accounting for your dog’s full-grown body. A puppy can manage with a tiny flap, but what happens if your large to giant breed grows up? A small dog can fit into a larger flap but not the other way around.
