2. PetSafe Sliding Glass Pet Door – Best Value

The PetSafe Sliding Glass Pet Door doesn’t cost significantly less than the Ideal Pet Products version, but there’s no denying that it is a bit less expensive. This makes it the most affordable option on our list, and PetSafe didn’t sacrifice the quality of the product in any way to get there.

It’s super easy to install without any additional hardware, and there are tons of flap size dimensions to pick from so you get the perfect option for your pup. It also fits a wide range of door sizes, so you shouldn’t have any problems installing it on your sliding glass door tracks.

Another advantage of this sliding glass door is that it comes in three different color options, making it easier to match with everything that’s already there.

However, it is our budget choice for a reason, and that starts with appearance. While it’s not bad looking, it does look like a budget dog door. Add in that it doesn’t have any advanced features and you can see why it’s not at the top of our list.

But with everything it does offer at this price point, it’s not hard to see why it’s our best dog door for a sliding glass door for the money.

3. High Tech Pet Products Large Pet Patio Door – Premium Choice

If you want a dog door for your sliding glass door that looks and feels like a premium product, the High Tech Pet Products Large Power Automatic Sliding Glass Pet Patio Door is an outstanding choice. It fits a wide range of door sizes, and it fits larger door frames than most other products accommodate.

It’s another dog door that’s easy enough to install on a sliding glass door track, and it looks great when it’s on. Just keep in mind it does only come in one color option, but since white is the most common color for a sliding glass door, this isn’t a huge deal.

This dog door and panel are also extremely durable, so you won’t have to worry about replacing it anytime soon. But while all this is great, it is a much more expensive option, and the only feature it has to justify the higher price is the self-closing and self-opening feature.

This feature works with a collar you put on your dog, and when they get close to the door, it’ll open for them and quickly close behind them. It’s a great feature, but it’s up to you to decide if you think it’s worth the extra money you need to spend to get it.

4. High Tech Pet Products Medium Pet Patio Door

This High Tech Pet product is almost identical to the one we listed above. However, the most notable difference between the two options is the size of the flap on the door itself. You still get to fit a ton of door options, including extremely large doors, despite the “medium” in the name.

All this is talking about is the size of the flap on the door, and if you don’t have an extremely large dog, you can save yourself some money by going with this option instead.

It’s extremely durable, easy to install, and most importantly, it still has self-closing and self-opening features. It’s a more expensive option for sure, but if you like the automatic features, it’s well worth the extra money.

5. Endura Flap Vinyl Sliding Glass Dog Door

The Endura Flap Vinyl Sliding Glass Dog Door is the last option on our list, but that doesn’t mean it isn’t worth checking out. You can pick from multiple sizes to get one that matches the size of your door frame and there are multiple flap sizes you can pick from.

This gives you a ton of options and the ability to find the perfect dog door for you. This dog door and panel also come with a lifetime warranty, so if you ever have any problems with it, Endura Flap will make it right.

But even with this, it fell to the bottom of our list for a reason. First, it’s an extremely expensive option, and it doesn’t have any advanced features to help justify the cost. The lifetime warranty does help a bit, but it’s also by far the most challenging option to install on our list.

It comes with everything you need, but it’s not anywhere near as simple as the installation of the other dog doors for sliding glass doors on our list.

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

It’s perfectly normal to have a few questions about what you need and how to install a dog door on a sliding glass door. It’s not something most of us do every day, so it’s a good idea to get as much information as possible before you start.

We completely understand how it can be hard to make a decision, which is why we came up with this buyer’s guide to walk you through everything you need to know before ordering and to highlight what to do after you get it.

What to Know Before Ordering a Dog Door for a Sliding Glass Door

By far the most important thing to know before ordering a dog door for a sliding glass door is the dimensions surrounding your current sliding glass door. Not only do you need to know the dimensions of the door frame itself, but you’ll also need to know the dimensions of the track it’s sliding on.

You need to compare all these measurements with the measurements of the dog door you’re getting because if it doesn’t fit, there’s no reason to get it!

Next, take the time to measure your dog. If they won’t fit through the dog door, they won’t use it, and you’re going to spend your money and put in the time to install it only to find that they’ll never use it.

Finally, do yourself a favor and look at the appearance of your current sliding glass door and compare it to the dog door you’re getting. You’re installing a whole new panel here, and you want it to fit in with the rest of the décor. It’s easy to overlook, but it’s a significant factor when purchasing a dog door for a sliding glass door.

Advantages of a Dog Door

For the most part, dogs love dog doors. This gives them the freedom to access both the inside and outside of your home whenever you want, which keeps you from constantly needing to get up and down to let them in and out.

This means you won’t need to worry about them having as many accidents inside your home, and often, your pup will bark less. Additionally, if you have a larger property, your dog can spend more time outside running around, which is great for their health!

Finally, if you’re out for a longer period of time throughout the day, a dog door means you don’t need to pay someone to come let them out, and your dog won’t have to hold it all day.

Disadvantages of a Dog Door

While dog doors have a ton of advantages, they’re not the perfect solution. One of the most notable drawbacks of dog doors is that while they can let your dog out whenever they want, they can also let other things in.

Stray cats, skunks, and opossums are common visitors, but depending on where you live and the size of your dog door, you might have to worry about raccoons or even coyotes. Automatic dog doors can help with this, but they cost significantly more.

Another disadvantage of dog doors is their lack of insulation. While newer dog doors have features to help with this, they don’t work quite as well as a solid glass pane.

Installing Your Dog Door

Once you get your dog door in the mail, it’s time to install it. Since you already (hopefully!) measured the door and compared it to the dog door you ordered, it should fit like a glove.

The good news is that every dog door on our list comes with detailed installation instructions when you get it. This cuts out a bunch of the guesswork and ensures you properly install it the first time.

Our only piece of advice is to get a second person to help you with the installation process. The glass door can be heavy, and the last thing you want to do is drop the glass panel right after you get it.

How Much Do People Charge to Install a Dog Door on a Sliding Glass Door?

If you’re thinking about skipping ordering a dog door for a sliding glass door and just calling out a professional to do it for you, you might want to think again. While you can get and install a dog door for a sliding glass door inexpensively, if you’re looking for someone to do it for you, they’ll typically charge quite a bit more.

Labor alone for the installation of these doors costs between $300 and $500, so if you’re looking for a more advanced dog door for a sliding glass door, you can expect to spend a fair amount.

Considering how easy it is to install these doors yourself, we highly recommend taking the initiative and doing it yourself.

Conclusion

If you’re still debating about which dog door is right for you after reading the reviews, go with either the Ideal Pet Products Aluminum Modular Pet Patio Door or the PetSafe Sliding Glass Pet Door. They’re our top two choices for a reason, they look great, are affordably priced, and will last a long time.

And if you’re worried about wildlife getting in through the dog door, go with one of the High Tech Pet Products dog doors. With the automatic opening and shutting features, you can eliminate that concern completely while still giving your pup the freedom they want and need.
