For 30 years, Moore Pet Supplies has helped pet owners across America give their dogs and cats more freedom, comfort, and independence. A pet door is one of the best upgrades you can make to your home—but with so many sizes, styles, and features available, choosing the right one can feel overwhelming.

The good news? Finding the perfect pet door doesn’t have to be complicated. By focusing on a few key factors, you can quickly narrow down your options and select a door that fits your pet, your home, and your lifestyle.

Start With Your Pet’s Size and Needs

The most important step in choosing a pet door is selecting the correct size. Measure your pet from the floor to the top of their shoulders and from side to side at their widest point. These measurements will help you determine the minimum flap size your pet needs to pass through comfortably.

If you have a growing puppy or multiple pets of different sizes, it’s usually best to choose a door that fits your largest pet. Cats, small dogs, large dogs, and even extra-large breeds all have pet door options designed specifically for them.

Think About Where the Door Will Be Installed

Pet doors can be installed in many locations, including exterior doors, walls, sliding glass doors, and even screen doors. The installation location often determines which type of pet door will work best.

For example, a traditional door-mounted pet door may be perfect for a back entry door, while a wall-mounted model might be better if you want more flexibility with placement. Sliding glass door inserts are a great option for renters or anyone who prefers a no-cut installation.

Consider Weather and Energy Efficiency

If you live in an area with hot summers, cold winters, or both, energy efficiency is an important factor. High-quality pet doors with insulated flaps and strong weather seals help keep outdoor temperatures outside where they belong.

Investing in a well-built, weather-resistant pet door can reduce drafts, lower energy bills, and keep your home more comfortable year-round.

Security Matters Too

A pet door should provide convenience without sacrificing safety. Many modern pet doors include locking covers or security panels that allow you to control when the door can be used. Some advanced options even offer electronic or microchip-controlled access so only your pets can enter.

Choosing a secure, durable pet door gives you peace of mind while still giving your pets the freedom they love.
