The 5 Best Dog Doors for Sliding Glass Doors

1. PetSafe Freedom Aluminum Pet Door – Best Overall

The idea of a dog door in a sliding glass door might give you a headache when you think of the installation, but with the PetSafe dog door, the process is simple. Instead of actually changing your sliding door, this is an insert that will go between the wall and the sliding door, allowing your dog easy access to your shared home. Because installation involves simply sliding this into place, this product is adjustable when it comes to sizing.

It may seem like this wouldn’t be efficient for your monthly bills, but PetSafe has made a product that seals up and still allows your pet to come and go as they please! Even during the hottest days of summer or the coldest days of winter, this door will keep the elements exactly where you want them: outside! You can get this door in a variety of sizes and colors to match the size of your door and the décor of your home. You will, of course, want to measure your door before placing an order for this product.

This is a wonderful product for homeowners, as well as for renters, because it leaves no trace, doesn’t involve any drilling, and is easily detachable so you can simply pick it up and move it when you pack up and move!

However, this door is not necessarily the best if you live in an area that gets extreme winters. While it can handle cold weather, it doesn’t hold up well to extremely cold weather. Also, adding this to your sliding door can make some locks on certain doors inoperable, which will mean you will have to either get creative in order to make them work or trust that no one will try to break into your home. Overall we think this is the best dog door for sliding glass available on the market.

2. Ideal Pet Products Pet Patio Door – Best Value

Ideal Pet Products has products that are ideal for pet owners as well! This is the case with its aluminum pet patio door. This door is simple to install and take down, which makes it a wonderful product for people who rent instead of own. There are no tools required, which certainly increases your chances of getting your security deposit back. This product is also adjustable, so it can suit different-sized doorways.

The aluminum gives it a classic look, though it does mean that it can only be used with aluminum sliding glass doors. This product also comes with a sliding insert for you to place during the night to make sure that nocturnal animals, such as raccoons and possums, don’t get into your house.

This door is not without its issues. Certain doors will not be able to lock once this is installed. Also, this product is only good for people who live in areas with moderate weather. If used in extreme cold or heat, you could see a significant rise in your bills. Sometimes the door flap gets a bit stuck, but that is easy to fix. Even with these issues, this is the best dog door for sliding glass doors for the money.

3. High Tech Pet Products Automatic Sliding Glass Door – Premium Choice

The High Tech Pet Products Automatic Sliding Glass Door is operated via a pet collar sensor. As your dog approaches, the door slides open and into the door housing. Once your dog has passed through, the door firmly and securely closes again, until it recognizes that your dog is approaching to come back in. Perfect for dogs with incontinence problems and who can’t make it through the night, this automatic sliding pet door is also a good choice for owners who will be away from the house for long periods.

The door fits into the track of a sliding patio door. It has a spring-loaded top section for ease of installation, although it will take two people to install it properly and safely. The whole unit is a dual-panel, which is designed for energy efficiency, so it will not allow heat to pass out. It has a draft excluder to prevent cold air from getting through the door panel, and weather stripping prevents rain and water from getting in.

This door is suitable for dogs up to a medium size, which means that it should be suitable for Labradors and Retrievers, although it may not be suitable for larger breeds. Although it is quite expensive, the weatherproofing; sensor operation; and high-quality components make this a beneficial choice for your dog and also for your home.

4. Endura Flap Vinyl Sliding Glass Dog Door

The manufacturer of this product should look quite similar to you! We were so impressed by Endura’s patio effort, we wanted to highlight another one of their offerings: the vinyl sliding glass door. The price might make you do a double take, but the people who have these in their homes swear by them and do so for years.

You will need to measure your door frame before you purchase. The installation is similar to the one for patios in that it is simple, but there is still a bit of work that requires elbow grease. The main difference is that this product was made for vinyl sliding doors and can withstand brutal weather. This product will fit perfectly in with your vinyl siding, as well as be able to withstand winds of up to 50 MPH and temperatures as low as -40 degrees. That’s pretty heavy-duty if you ask us!

This product comes with a 15-year warranty.

5. Whiskers & Windows Dog Door

This door is good, but when it comes to keeping out the elements, it is closer to our first two picks than the selections from Endura. Price is what lands it at number five on our list.

Don’t get us wrong, this is a fine dog door! Installation is easy, as it is spring-loaded and fits right into the doorway. The dog door itself is insulated with foam to keep the weather out and your bills low. While this isn’t as heavy-duty as the Endura doors, it still does a good job.

However, you will need to purchase weather stripping separately from this item. While it is not strictly necessary, it certainly helps, especially if you live in an area that really sees the elements. That’s one gripe we have about this door. Another is that this only fits specific sizes. There are some doors where this just won’t fit. This is a high-quality door, but it isn’t quite as revered as Endura doors.

Buyer’s Guide: Choosing the Best Dog Doors for Sliding Glass

When buying a sliding glass door doggy door, you’ll need to be mindful of more than just if your dog can freely roam. You also need to worry about insulation, installation, and whether pesky night critters can get into your home. Let’s take a look at a few things to consider when buying a dog door for your sliding glass door.

Will your dog fit?

It’s one thing to know that your dog will fit through the dog door, but it is a different thing to make sure that the sizing is proper so your best friend doesn’t wind up with any odd injuries. How do you do this? First, when measuring, you want to measure the width of the opening for your pet, not your pet directly.

Then, you will want to make sure that your dog can easily step over the threshold and that it does not scrape their belly.

Lastly, you want to make sure that there is at least a 1-inch clearance between your dog’s back and the top of the opening, though we recommend 1.5 inches just to be safe.

Will the door fit?

Some doors are adjustable to the point where you can get them to fit in anywhere. Others come with specific measurements. Our research indicates that the more adjustable a door is, the less effective it is for harsh weather and keeping your bills to a minimum.

Security

If you decide to use one of these doors, you are not guaranteed that they will be compatible with the locks on your sliding glass door. If this is important to you, either do your research first or check the return policy of the door you are buying.

Warranty

We recommend looking into warranties with any purchase you make, especially if it is an item you expect to have for a long time. Different companies do warranties differently, and it is worth it to make sure you know how to have them honored, how long you have them for, and if they even exist!

Conclusion

Getting a doggie door is an exciting addition to any home, as it gives freedom to both you and your pet (you won’t have to be constantly on call when your fuzzy pal wants to go outside). Training them to go in and out can be a little difficult, but in the end, it is all worth it.
