This Review has been updated 6 times since it was first published in October of 2018. If you’re tired of having to constantly let your animals in and out when nature calls, these pet doors will allow them to come and go at their leisure. They install directly into your existing sliding glass doors, but be aware that any model that works on vinyl doors won’t work on aluminum ones, so be sure to check the details thoroughly before you decide which one to purchase. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Review. Skip to the best sliding glass pet door on Amazon.
6. High Tech Pet Shorty
If you don’t want your furry friends to have to do any work, the High Tech Pet Shorty is a fully automated sliding door that activates whenever your pet gets close. It uses an ultrasonic collar to detect their presence, so you won’t accidentally let in a raccoon.
- Won’t shut if animal is in the way
- Hard to keep collar in place
- Lets quite a bit of air in
5. Ideal Pet Products VIP
For owners with vinyl doors, there’s the Ideal Pet Products VIP. It has a two-pane glass window that’s great for keeping the cold or heat out, and it’s heavy enough that you shouldn’t need to worry about your pooch knocking it over. Installation is a pain, though.
- Flap doesn’t blow open
- Good for wide frames
- Makes a lot of noise when in use
4. Endura Flap Thermo
The magnetic seal on the Endura Flap Thermo is adjustable, so if your kitty is struggling to burst through the flap, you can turn the resistance down. It also comes in handy on windy days, as you can make sure that dirt and debris stay outside, where they belong.
- Includes weather stripping
- Tool-free installation
- Made with eco-friendly materials
3. PetSafe 2-Piece
Available in three sizes, the PetSafe 2-Piece can accommodate animals of up to 100 pounds, so many large-breed dogs can squeeze through without an issue. It’s not engineered to be a permanent installation, so it’s not as sturdy as other options, but it is easier to set up.
- Doesn’t require drilling holes
- Good for senior pets
- Easy-to-follow instruction manual
2. Ideal Pet Products Fast Fit
The Ideal Pet Products Fast Fit lives up to its name, as it’s easy to put up and take down, making it a smart choice for renters. The clear flap helps during training as well, as Fido can see the yard from inside and won’t think you’re asking him to run through a door.
- Very attractive once installed
- Sturdy aluminum frame
- Adjusts from 77 to 81 inches
1. PetSafe Freedom
If you’re worried about letting bugs in with your dog, the PetSafe Freedom has a magnetic closure on the flap that keeps it closed when it’s not in use. That will also prevent any heat or air conditioning from escaping, so you won’t have to deal with a huge energy bill.
- Aluminum frame with tempered glass
- Leaves lots of room for people
- Includes security panel
