Buying dog doors for big dogs allows them easy access to the outdoor world. If your pooch drives you crazy and always wants to go outdoors at the wrong time, then buying one of these would be a lifesaver for you.

Installing a dog door cuts the hassles in half! Not just that, but it allows your dog to tend to its innate needs as and when it wants. That brings up the question, what are the best big dog doors?

Before we move on to answer that question, let us convince you why big doors are actually important for dogs. Although opening regular dog gates is quite straightforward for us humans, dogs require supervision, which can quickly get hectic for you!

So, here’s the list of the pros of getting a dog door installed:

  1. Convenience – your pet can go in and out without supervision
  2. Freedom – let your pup explore the outdoors with free will
  3. Escape-Proof – in case something unfortunate happens, your dog can safely move in and out of the house

Even though these are the major positives, the list of pros for dog gates is endless. Now, although you can quickly train your dog to use the door you’ve installed, getting the right size is crucial too. A large pooch might struggle to go out a medium-sized door. That is precisely why measuring your dog’s size is essential as well.

Thus, before you pick a dog door, make sure the door’s size is appropriate for your dog, otherwise, your doggo might not use the door at all.

How to Choose the Right Door for Your Big Dog

Next, let’s take a look at some tips you can use to pick the right dog door for your pup. Generally, every dog door has its pros and cons. Make use of these tips to ensure that the door you’ve picked fits both you and your dog’s needs.


Dog doors are made from a variety of materials like aluminum, plastic, and glass. Although metal might be the most durable, high-quality material, plastic doesn’t lag behind.

You should choose a door that allows your doggo to pass through easily and can withstand your dog’s strength. However, durability is still a major concern and should be an essential criterion in your selection.

Easy Installation

If you’re not a naturally blessed handyman, then pick a dog door that requires the least troubleshooting and can be easily installed. Also, make sure the product has appropriate instructions provided, so you don’t have to waste money on acquiring external help in installing the door. Some people prefer sliding glass dog doors over flaps; what is your preference?


One of the most pressing concerns with dog doors is security. For obvious reasons, you won’t be welcoming other animals or critters into your house.

It is highly recommended that you pay extra attention to the security features provided with your door. Again, make sure the product or brand you pick can only allow your dog to pass through. This might be achieved by installing microchip doors for large breeds. Other than that, the door should have a sound locking mechanism for the times when you’re not home or don’t wish to keep it open for your dog.


Energy-efficiency might be another essential aspect when purchasing a dog door. Since it is another opening for air to pass through, you might want to have a well-insulated gate.

Manufacturers usually take care of this by installing several flaps to the door. So this way, the house’s temperature doesn’t fluctuate, and the house remains well-ventilated. This feature is crucial for anyone residing in a place with extreme weather conditions (hot or cold).


As discussed, measuring your dog’s size is extremely important before purchasing a dog door. Door sizes vary and don’t cater to specific dog sizes. Instead, you’re required to pick the product that best fits your dog’s size.

Dog doors for big dogs cater to these issues extensively and have adequate space for your pooch to pass through. However, as a rule of thumb, you should measure your dog and add an inch or two to that measurement. This way, you’re always on the safe side of things.
