Dog Door Sizes: How to Choose the Right One for Your Pet



Dogs have a strong, in-built instinct to protect members of their pack and seldom want to be separated from them. In these domesticated times, your family becomes your dog's pack. He's happiest when he can hang out with you, but also patrol the edges of his territory. So if you'd prefer not to have to jump up to open the door every few minutes, a dog door is a perfect answer. If the thought of installing a door that allows your dog to let himself in and out again sounds good to you, keep reading for the lowdown on dog door sizes. 

Do Dog Door Sizes Matter? 

Matching the size of the dog door to the size of your dog is important to prevent your pet from picking up injuries. While squeezing through a small opening once probably won't do any damage, continually squashing themselves to get through a doorway that's too small can lead to hip or shoulder injuries. 

Small dogs, however, can use a bigger dog door as long as they are strong enough to open it. So if you have a multi-dog household, base your dog door sizing on your biggest fur-buddy. 

How to Measure A Dog Door Size

To make sure you're getting the right size dog door, you'll need to dig out your measuring tape. Three measurements are essential for installing the right size door for your dog. Once you have these measurements, you can find the standard door size that is closest to your doggy's measurements. 

1. Width

Find the widest part of your dog, measure it, and add on an inch or two for wriggle room. Long-haired pets may appear wider than they really are thanks to their fluff. If your dog won't stand still long enough for you to take the measurement, hold a door open just wide enough for them to come in. Use the opening as your guide. Measure it and add on an inch or two wriggle room.

2. Height

Your dog's height isn't measured to their head, but rather from the floor to their shoulders. If your dog won't stand still long enough for you to measure, simply mark where their shoulder comes up to against your leg. Use a measuring tape to get the distance from there to the floor and add a couple of inches.      

3. Rise

Rise is the height above floor that the dog door is mounted at. Most dog doors can be mounted at whatever height is comfortable for your pet. If you have an older dog or a breed that has short lets, you can opt for a 'no-rise' door.
