Choosing the Best: What to Look For

So, now that you know about the top choices available, how did we decide what made the cut? There are a handful of features we suggest considering when shopping around for a pet door for your sliding glass door. 

Dog Size

Start with the size and breed of your dog. While cats can easily slip through small spaces, dogs aren’t quite as flexible. Make sure the panel is big enough for your pup to fit through without scraping any area of their body.

Your Door

Next, take a look at your sliding glass door. You’ll want to consider what material it’s made out of, what size the tracks are, and if you need to use the door as well. Many pet doors that get installed into sliding glass doors make the door inoperable for humans. 

Your Outdoor Space

While it totally depends on the pet parent, we suggest using one of these doors if you have a fenced-in backyard or if your pet is trained not to leave a certain area. As it gives your pup the opportunity to come and go as he pleases, it’s essential to make sure that it’s safe enough for him to do so. 

Dog doors are intended to give your pets easy access. But they can also provide an entryway for criminals and wildlife. So whether your neighborhood attracts raccoons or cat burglars, consider your options of keeping them away from the dog door. You might buy a lockable door that you can snap shut at night. Or a door that only opens when it spots your pet’s ID chip.

Local Weather

As you read in some of the reviews, not all dog doors for sliding glass doors are made for all-weather types. If you live in an area that experiences heavy rain, make sure you get one that has weather sealing. If you’re in a state that has extreme heat or cold, you’ll want a weatherproof dog door. 

The Different Types of Dog Door for Sliding Glass Doors: Pros and Cons Compared

Not all dog doors for sliding glass doors are the same. Let’s take a look at some of the most common benefits and disadvantages. 

  • Sensor-Activated: This type of dog door is great because it prevents other animals from coming in. It will only open if the sensor is within three feet. The main downfall of this type of dog door is that they tend to be more expensive for added security. 
  • Flap Panel: We suggest this type if you have a trained dog with a fenced-in yard. A flap panel gives the most freedom to your pet. The disadvantage to this style is that it isn’t the most weatherproof option available.
  • Aluminum: Dog doors that are made out of aluminum are incredibly lightweight and easy to install. They’re great for renters as this type of dog door doesn’t require tools. Most of them only fit in aluminum sliding glass doors. 
  • Weatherproof: In general, weatherproof dog doors for sliding glass doors are good for anyone. It doesn’t matter where you live, as the weatherproofing can handle cold, heat, rain, snow, and wind. This is an option that tends to be on the pricier side of things. 

Our Criteria: How We Chose the Best

The choices we selected are made to stay airtight. The seals and linings, some made of aluminum, help prevent outside air from seeping though. Plus, the doors themselves seal tightly, some using magnets. We love this feature because it helped us cut down on electric bills.

Our selections provide options for easy installations if you are a do-it-yourself kind of person. The PetSafe Freedom Aluminum Pet Door, for example, comes with easy-to-follow instructions including a template for cutting the hole in your door.

We hope that this product review has provided you with some useful information to help you to choose the perfect door for your pet.
