Choosing the right pet door is one of the best investments you can make for your pet and your home. With so many options available today, it’s important to understand what features matter most so you can make a confident, informed decision. Whether you have a playful puppy, a curious cat, or multiple pets, the right pet door improves daily life for everyone in your household.

At Moore Pet Supplies, we’ve spent 30 years helping customers find the ideal pet door solutions, and we’ve learned exactly what separates a great purchase from a regrettable one. This complete guide walks you through everything you should consider before buying.

Step 1: Choose the Right Size
Size is the most important factor when selecting a pet door. Measure your pet’s height from the floor to the top of their shoulders and their width at the widest point. Your pet should be able to pass through comfortably without crouching or squeezing.

If you have multiple pets, always size for the largest one. A door that’s too small won’t be used, and one that’s too large can reduce energy efficiency if it’s not properly designed.

Step 2: Decide Where to Install It
Pet doors can be installed in several locations, and the best option depends on your home layout:

• Entry doors for quick and simple installation
• Walls for custom placement and flexibility
• Sliding glass doors for no-cut solutions
• Screen doors for seasonal convenience

The installation location affects not only convenience but also insulation, accessibility, and long-term durability.

Step 3: Look for Energy Efficiency Features
A well-designed pet door should help maintain your home’s indoor temperature—not disrupt it. High-quality models include features like insulated flaps, tight weather seals, and strong frames that reduce drafts and prevent outside air from entering.

Energy-efficient pet doors are especially important if you live in regions with extreme temperatures. They can help maintain comfort while reducing strain on your HVAC system.

Step 4: Consider Security Options
Security is a common concern for homeowners considering a pet door. Fortunately, modern pet doors offer excellent solutions. Many include locking covers, reinforced frames, and heavy-duty flaps designed to prevent unwanted entry.

Some models also offer advanced access control features, allowing only your pet to use the door. This adds peace of mind while still giving your pet freedom.

Step 5: Think About Long-Term Durability
A pet door isn’t something you want to replace every year. Durable construction, replaceable parts, and quality materials ensure your door will stand up to daily use for years to come.

Investing in a well-built product upfront often saves money over time and prevents frustration caused by worn-out components or poor performance.
