Perfect Dog Doors For Large Dogs In 2022

Finding the perfect dog door for large dogs takes time as you have to look around at the limited options. Most manufacturers focus on average-sized dog doors due to the available market and cost of production.

With most large dogs being powerful chewers, you need a door with well-built materials that can withstand any impact. It should also be strong enough to handle the weight and size of your furry buddy.

Good news, you don’t have to go through the tedious process of looking around for the right large dog door. We have done it all for you. Here’s your comprehensive guide to dog doors for large dogs, irrespective of your budget and dog security and comfort needs.

Types Of Dog Doors

You can choose from several dog doors depending on your needs and preferences. They include:

Door In Door

These dog doors come as a kit ready for installation in the lower portion of the door. They are often easy to set up yourself, except for glass storm doors, which might require special expertise and tools.

Avoid cutting holes in the door during installation, as it can lead to the voiding of the warranty. Instead, invest in a polished, cohesive look by choosing the doors that have in-built pet access already set up at the factory.

Through The Wall

From time to time, you may want to introduce a dog door to a wall where one doesn’t exist. Maybe you want to take advantage of the lighting or need better access to your porch. Creating a space and then installing the door on the wall is the easy way out.

While you may freak out about the prospects of the wall, most doors don’t compromise the stability of the building. However, walls thicker than the common 2×4 might need special attention.

Regular Dog Door

The standard or regular dog doors are the common ones made to fit exterior doors. There are also some designed for interior doors. Ensure you match the door type to its design; don’t use an interior design for the exterior door.

A typical regular dog door is made of a metal or plastic frame and a vinyl door flap. It can also have an additional panel for locking when needed.

Sliding Doors

These are specially designed dog doors to fit sliding doors. They are easy to install as you don’t have to make cuts or holes when fitting. Instead, you place it in the space between the wall and the door.

Most sliding doors have flexible flaps like regular ones, with some also having lock panels.

Screen Doors And Porches, Dog Doors

Screen doors and porches are designed to fit in the screened-in style of the door. They are a little hard to choose the right one as you have to find the best design without compromising on being rigid enough to hold big dogs.

Style doors are some of the most efficient screen and porch doors. They allow for easy in and out of the dog’s passage and often have magnets to keep the door locked after use.

Factors To Consider When Buying An Extra Large Dog Door

With limited top-quality options available on the market, choosing a dog door for your large dog can be time-consuming. Here are some factors you need to consider to save time and energy.

1. Locking Mechanism And Security

The dog door you purchase is more than just securing your dog. You will sometimes need it to stop the dog from going through it. That’s why you need one with a strong locking panel.

While some dog owners go for cheaper doors to save money, most tend to need more adequate locking panels. This can be a risk you don’t want to take.

Your dog door should guarantee your security and that of the dog. It should effectively keep away criminals, wild animals, and other intruders.

2. The Size Of Your Dog

You need a comfortable dog door that fits your dog perfectly. Ensure you measure the dog before you order to ensure it will fit. At the same time, you must pay attention to the manufacturer’s weight and height limits directions.

Remember to get a door that leaves a little wiggle room for your dog. This way, you won’t have to worry about replacements if it adds weight.

3. Materials And Durability

Large dog doors come in a wide range of materials, including aluminum, plastic, vinyl, metal, and glass. Choose a durable material you don’t have to replace every other time. You should also go for the “chews” that can withstand stronger chewing from large dogs.

4. Location

Where you live determines the kind of dog door you purchase. Extreme climates and weather conditions require a sturdy door. Find an airtight door with some kind of seal, like a magnet. These help keep out rain, snow, or extremely hot or cold air.

5. Warranty

Most large dog doors are expensive, and a warranty guarantees the expenditure is worth it. Look for extended warranties lasting for years. The more a manufacturer believes in their product, the longer the warranty.

Extra-Large Dog Doors FAQs

Can a person fit through a large dog door?

Most of the extra-large dog doors are big enough that a human can fit through. While it might be good for you if you need to fix something, it can be a security concern.

Keep the premises safe by installing safety features like locking panels or microchip collars for the dogs.

You can also opt for automatic doors that only open when the dog approaches. At the same time, remember to keep the system secure for humans who need it.

Can I install my large pet door into glass?

While most large dog doors are known for fitting into walls, you can install them in glass. However, in most cases, you will need a professional to help you. Never attempt to cut the glass window or door yourself.

How do I train my dog to use the dog door?

Buying a large dog door does not guarantee your dog will start using it instantly. You have to first train them to use it. While at it, give them treats and rewards to get them more involved.

You can then determine how the dog prefers to use it, whether going in or out. Encourage their preferred method; with time, they will get used to the door and utilize it both ways.
