One of the biggest concerns homeowners have about installing a pet door is security. It’s a valid question—any opening in your home should be carefully considered. The good news is that with the right product and setup, you can enjoy the convenience of a pet door without compromising your home’s safety.

At Moore Pet Supplies, we’ve spent 30 years helping pet owners find solutions that balance freedom for their pets with peace of mind for their homes. Here’s how to keep your home secure while using a pet door.

Choose the Right Size (Not Bigger Than Needed)
A properly sized pet door is your first layer of security. Oversized openings can create unnecessary risk, while a door tailored to your pet’s size provides functionality without excess space.

Always measure your pet carefully and choose a door that fits comfortably—but not excessively.

Use Locking Covers or Security Panels
Most high-quality pet doors include a locking panel or sliding cover. This allows you to completely block access when needed, such as overnight, during travel, or when you’re away from home.

This simple feature gives you full control over when the pet door can be used.

Install in a Smart Location
Where you install your pet door matters. Placing it in a fenced backyard or a less visible area of your home can add an extra layer of security.

Avoid highly visible front-facing locations when possible, and think about how accessible the door is from outside.

Invest in Quality Construction
A well-built pet door is much more secure than a low-cost alternative. Strong frames, durable flaps, and tight seals all contribute to overall performance and safety.

Cheap pet doors are more likely to have weaknesses that can be exploited or that deteriorate over time.

Maintain Your Pet Door Regularly
Security isn’t just about installation—it’s about upkeep. Regularly check your pet door for wear, loose components, or gaps that could affect performance.

Keeping your pet door in good condition ensures it continues to function as intended.

Consider Your Overall Home Setup
A pet door is just one part of your home’s overall security. Fencing, lighting, and general home layout all play a role in creating a safe environment.

When combined with a thoughtful setup, a pet door becomes a secure and practical addition to your home.

Convenience Without Compromise
A pet door should make life easier—not create new concerns. With the right approach, you can give your pet the independence they need while maintaining the security you expect.

For three decades, Moore Pet Supplies has helped homeowners choose pet doors designed for real-world performance. That commitment to quality and reliability is why we continue to be known as America’s #1 Choice for Pet Doors.

With smart choices and proper setup, you can enjoy the best of both worlds—freedom for your pet and confidence in your home’s security.
