As your Great Dane grows, you might start to consider getting them a dog door that accommodates their size. Many pet owners consider dog doors an excellent investment. However, you might have trouble finding the perfect dog door that suits your dog and your home. 

We compiled a list of the best Great Dane doggie doors to help you narrow down your options when looking for dog doors for large dogs.

What’s the Best Great Dane Doggie Door?

If you’re in a hurry, we’ll just get straight to the point for our top selection.

Our overall winner for best Great Dane doggie door is the PetSafe Extreme Weather Doggie Door. Although all five of our picks have excellent features, this model’s three-layered insulated flap design for large dogs and easy DIY installation make it stand out from the others.

Reach for the PetSafe Extreme first if you have a Great Dane!

PetSafe Extreme Weather Dog Door

First, we’ll start our rundown with the best overall dog door option. The PetSafe Extreme Weather Pet Door comes in four sizes, with its extra-large model appropriate for Great Danes. It’s an affordable dog door suitable for most homes, making it a safe option for people with limited budgets seeking a functional model. 

Like most large dog doors, it comes with a plastic or aluminum frame. However, we think the aluminum might be more valuable to you because it’s more likely to resist outdoor weather damage. Unfortunately, it’s only available in white, but you can paint it to match your door’s color during your free time.

Buying Guide for Great Dane Doggie Doors

Before deciding on which Great Dane dog door you want to purchase, there are several things you should consider. While many of these factors revolve around the door’s functionality, they should also reflect your lifestyle. 

As we reviewed our top picks, we considered the following questions you might have and the characteristics that matter when scoping out your best fit.

Why a Dog Door?

Many pet owners consider dog doors a valuable investment for several reasons. One universal reason people install them is to provide dogs easier access outside when they need to use the bathroom. 

This solution is ideal if you don’t want to clean up accidents around your home. In addition, you can focus on other responsibilities by not opening the door every few hours for your dog, especially when you’re at work. 

Installing a dog door that leads to your backyard encourages exercise and counteracts boredom after spending long hours alone. By leaving them cooped up all they, they might start chewing your furniture or develop separation anxiety. 

It’s also an essential tool for letting temperature-sensitive Great Danes access your home to escape intense weather conditions.

What Size Dog Door Do I Need?

Before buying a Great Dane dog door, you’ll need to know how it fits into your door and how well your Great Dane can fit and walk through it comfortably. While it might be easier to assume that one size fits all doors, that’s not always the case. 

You have to put some effort into finding the perfect fit for your home by measuring your door and your pet.

Measuring Your Great Dane to Get a Perfect Doggie Door

You can determine your Great Dane’s height by measuring from the floor to the tips of the dog’s shoulders. Depending on your dog’s age and gender, your Great Dane’s height should measure between 28 to 34 inches. 

When measuring your dog’s shoulders or hips, consider getting a dog door that’s two inches wider than this measurement if your dog gains weight.

Measuring your Great Dane’s weight is another factor that plays into choosing the best pet door. The maximum weight for most adult male Great Danes is 200 pounds, making them the perfect weight for XL dog doors. We recommend upsizing your door if you have a growing Great Dane puppy.

Points to Consider When Buying the Best Great Dane Doors

Before buying a Great Dane doggie door, you should consider several core elements that each one has. Although similar in design, many dog doors differ in several characteristics, from size to material. It’s your responsibility as a pet owner to choose the best, long-lasting dog door for a Great Dane. 

Door Flap Material or Style

Different manufacturers incorporate different materials for their door flaps. When selecting your ideal dog door, consider the material’s durability and how much strength your dog needs to use to push through it. Some popular choices include vinyl, magnetic, single flap, multi-flap, and plastic. 

Dog Door Height

The maximum dog door height determines how your dog fits through the entrance. The greater the height, the less likely your dog will need to crouch down when entering or exiting the house. Ideally, the door’s height should measure about one or two inches above the top of your dog’s back.

Dog Door Width

Width is another measurement that matters during the selection process. When the width is too narrow, your dog is more likely to get stuck and have trouble getting through. To avoid this inconvenience, measure your Great Dane’s hips and shoulders and add two inches to the broader body measurement. 

Door or Wall Style

Another factor to consider when searching for a large dog door is its compatibility with your doors. For example, your front door differs from your backyard sliding glass. The thickness of the door also affects how deep of a cut you need to make during your installation. 

Features to Look for When Buying a Great Dane Dog Door

When narrowing down options for Great Dane doggie doors, one thought might occur to you. While every large dog door on the market shares the same function, they aren’t all alike. Specific features can make or break a dog door, so it would be wise to pick a dog door for Great Danes that add value and functionality when used daily. 

Weather Resistance

A dog door with weather-resistant frames and flaps is an essential feature any house should use. Some typical weather you might experience include wind, rain, snow, moisture, and heat. While many large dog doors designed for enduring these conditions might be expensive, many are worth it in the long run. 

Energy Efficient Characteristics

This feature is essential for dog owners experiencing frigid winters or humid summers. However, this factor depends on the quality of the dog door’s flaps. Although many owners prefer using a single-flap dog door, models incorporating more flap layers retain lock air in a chamber, allowing less of it to escape.

This temperature balance is ideal for a Great Dane’s thin fat and coat layers.

Enhanced Locking Features

Installing a dog door for a Great Dane might make you start worrying about unwanted guests entering your home. Several dog door models incorporate slide-on or snap-on locks that let you seal them at night, during a storm, or when you and your dog leave the house, ensuring enhanced security. 

Electric models opened with your dog’s microchip or collar key can also keep outdoor animals and burglars out.

FAQs

Should I install an extra-large dog door when I have multiple pets?

It depends on what types of pets you have. We recommend picking a door with a height tall enough for your largest dog and a small step-over height for your smallest pets. An extra-large dog door is ideal for larger breeds, but can still accommodate smaller dogs or cats.

Does the entranceway’s height matter?

When selecting a Great Dane dog house or doggie door, height matters. Taller doors mean fewer chances of your dog injuring its back. Also, finding a dog door that matches your dog’s height prevents you from replacing it as he grows.

Should I reinforce my large dog door if it gets too drafty?

Although many dog doors have excellent resistance to high wind speeds, they might wear down over time or have varying protection quality. However, you can perform simple DIY solutions to seal a faulty dog door. 

These methods include caulking open holes or air gaps, adding weather strips around the frame, or installing more flaps into the door to minimize wasted energy.

Conclusion

After comparing and contrasting five of the best Great Dane doggie doors, we choose the PetSafe Extreme Weather Dog Door as our winner. Its affordable price point, American-made design, and frame material options put it at the top of any Great Dane owner’s list.
