What Size Dog Door Do I Need? Finding The Perfect Size Door For Your Dog

Anyone who enjoys being able to sleep in on holidays or weekends or through the night has probably never been woken up by a wet nose on the face waking them from a peaceful slumber. While some people might enjoy this quality “morning time” or “late night time,” others would much rather avoid the experience.

Rather than get out of bed to let out your dog, you might consider having a dog door installed.

Benefits of Having a Dog Door

In addition to being able to get a good night’s sleep, there are other benefits to having a dog door installed in your home. When pets go in and out, it burns more calories – and when pets have the option of going in and out on their own, they tend to do so quite regularly. Not only does this help reduce their weight, but it also has a distinct psychological advantage over pets that do not have dog doors.

Many pets are territorial, and whenever something might have disturbed their “turf,” they want to investigate. If your pet has a dog door, it can go out at any time and make sure there aren’t any unwanted trespassers hanging outside the perimeter.

When a pet is left alone, it can sometimes get anxious and nervous, leading to destructive behavior. Having a dog door available allows the pet to burn off that nervous energy.

You might wonder, “What size dog door do I need?

You’re going to want to measure for two things – flap size and stepover size. The incorrect size can cause problems down the road.

If you have a flap designed to let a Doberman through but your dog happens to be a chihuahua, the dog door might prove to be an insurmountable obstacle for it. The same thing goes for the stepover height. If the height makes the dog uncomfortable, it might not use it – and that defeats the purpose you had the door installed. This can be eliminated by hiring a professional dog door installer to come and install the dog door for you.

   Measure the width of your dog

In order to find the right size dog door we recommend measuring your pet from feet to shoulder. Naturally, the pet needs to be standing. Once you’ve got that measurement, you’ll want to go at least 1” above the pet’s back. As far as the stepover height goes, you’ll want to go with the height your pet is most comfortable going over. If you have any steps the pet climbs, the height of an individual step is one of the ways to determine the proper stepover height.

Measure the width of your dog

In the event you have multiple pets, you’ll want to measure both the tallest and the shortest. At the same time, if you have an older pet, you might want to have a shorter stepover height. As pets age, they lose some of their limberness and having a shorter stepover height means they will be more likely to use the door.

Kinds of Dog Doors

The variety of dog doors today is really amazing. At one time, a dog door was simply cut into a door and that was the end of it.

Now, with some of the advances in modern technology, dog doors can be quite sophisticated. Some of them, for example, actually will not open unless the pet is wearing a special collar that sends out a signal to unlock the door. This helps to keep any unwanted intruders from entering the house – whether it be human or even another animal.

There are also dog doors that are wall-mounted. In other words, if you don’t actually want to have a hole in your door, you can have one installed in the wall. (If you’re wondering why anyone would want to have a wall-mounted dog door, it makes sense if the door you’re sparing is an antique door or happens to be very expensive. It’s easier to patch a hole in the wall than to repair a door that has been used with a dog door.)

Yes, there are even dog doors available for people who have sliding glass doors and French doors.


Unless you happen to be a proficient handyman with the specialized skills needed to put in a dog door properly, this best left to professionals. When a dog door is installed by someone who knows precisely what needs to be done, you can be assured there are no draft leaks to worry about and that the installation is weather-proof and damage-resistant.

By choosing to install a dog door for your pet, you’ll be freeing yourself from having to get up in the middle of the night or in the early morning to let your pet out to go to the bathroom. At the same time, you’ll be giving your pet the freedom to come and go as needed. A professionally installed dog door can be one of the best decisions you can make for both yourself and your pet.
