Buying a pet door seems straightforward at first. Most pet owners focus on one thing: finding a door their pet can fit through. While size is important, it’s far from the only factor that matters—and overlooking the bigger picture is one of the most common mistakes homeowners make.

At Moore Pet Supplies, we’ve spent 30 years helping customers avoid costly frustrations by choosing the right pet door the first time. Here’s the biggest mistake pet owners make—and how to avoid it.

Focusing Only on Price
The single biggest mistake many pet owners make is choosing the cheapest option available.

At first glance, lower-priced pet doors may appear similar to premium models. But over time, the differences become obvious. Cheap materials, poor insulation, weak seals, and flimsy construction often lead to problems quickly.

What seems like a savings upfront can turn into frustration, discomfort, and replacement costs later.

Ignoring Energy Efficiency
Many homeowners don’t realize how much impact a pet door can have on indoor comfort. A poorly insulated pet door can allow drafts, heat loss, and moisture into the home.

This not only affects comfort but can also increase heating and cooling costs over time.

Choosing a well-sealed, insulated pet door helps protect your home while still giving your pet the freedom they need.

Choosing the Wrong Size
Another common mistake is guessing instead of measuring. A pet door that’s too small can discourage use, while one that’s too large may reduce efficiency and create unnecessary gaps.

Taking accurate measurements before buying ensures a better fit for both your pet and your home.

Overlooking Installation Location
Where the pet door is installed matters just as much as the product itself. A poorly chosen location can make the door inconvenient for your pet, expose it to harsh weather, or disrupt the flow of your home.

Thinking carefully about placement improves long-term satisfaction.

Forgetting About Durability
A pet door is used constantly—sometimes dozens of times each day. Low-quality products often wear out quickly under that kind of use.

Strong materials, durable frames, and replaceable components make a major difference in long-term performance.

Why Buying the Right Pet Door Matters
A quality pet door improves your daily routine, supports your pet’s independence, and becomes a seamless part of your home. But achieving those benefits requires choosing the right product from the start.

The cheapest option rarely provides the best experience.

For three decades, Moore Pet Supplies has helped pet owners invest in products designed for real-world use, long-term durability, and year-round comfort. That commitment is why we continue to be known as America’s #1 Choice for Pet Doors.

When it comes to pet doors, the biggest mistake isn’t buying one—it’s buying the wrong one.
