Buying a pet door seems simple—until you realize how many options are available. Size, placement, insulation, durability… the choices can add up quickly. Asking the right questions before you buy can save you time, money, and frustration.

At Moore Pet Supplies, we’ve spent 30 years helping customers make confident decisions. If you’re considering a pet door, start with these five essential questions.

1. What Size Does My Pet Actually Need?
This is the most important question. Measure your pet’s height (floor to shoulders) and width (widest point). The door should be slightly larger than these measurements to ensure comfortable use.

If you have multiple pets, always size for the largest one.

2. Where Will the Pet Door Be Installed?
Your installation location plays a major role in which type of pet door you should choose. Doors, walls, sliding glass panels, and screens all require different designs.

Thinking about placement ahead of time helps narrow down your options and avoid compatibility issues.

3. How Important Is Energy Efficiency?
If you live in a climate with hot summers or cold winters, insulation should be a top priority. A poorly sealed pet door can lead to drafts and higher energy bills.

Look for features like insulated flaps and strong seals to maintain indoor comfort.

4. How Durable Does It Need to Be?
Consider how often your pet will use the door. Active households or larger pets require stronger materials and more durable construction.

A well-built pet door will last longer and perform better over time.

5. Do I Need Security Features?
Many pet doors include locking covers or panels that allow you to control access. This is especially useful at night or when you’re away from home.

If security is a concern, choosing a door with built-in protection adds peace of mind.
