Choosing the right pet door is only half the decision—the other half is deciding where and how to install it. The three most common installation types are door-mounted, wall-mounted, and sliding glass insert pet doors. Each option has its own advantages, and the best choice depends on your home, your pet, and your long-term goals.

At Moore Pet Supplies, we’ve spent 30 years helping pet owners find the right fit. Here’s a clear breakdown to help you decide which installation type is best for you.

Door-Mounted Pet Doors: Simple and Popular
Door-mounted pet doors are installed directly into an exterior door and are the most common option.

They’re a great choice if you want a straightforward installation and already have a convenient door location leading to your yard.

Best for:

• Quick and simple installation
• Lower upfront cost
• Easy access points like back doors

Things to consider:

• Permanent modification to your door
• Limited to existing door placement

Wall-Mounted Pet Doors: Maximum Flexibility
Wall-mounted pet doors are installed through an exterior wall, allowing you to choose the exact location that works best for your home.

This option provides more flexibility but typically requires a more involved installation process.

Best for:

• Custom placement
• Keeping doors intact
• Long-term, built-in solutions

Things to consider:

• More complex installation
• May require professional help

Sliding Glass Pet Doors: No-Cut Convenience
Sliding glass pet doors are designed to fit into your existing patio door track without cutting into your home.

They’re especially popular with renters or homeowners who want a non-permanent option.

Best for:

• No structural modifications
• Easy installation and removal
• Patio and deck access

Things to consider:

• May slightly reduce door opening space
• Requires a properly fitting insert

Which Option Is Right for You?
If you want the simplest and most cost-effective solution, a door-mounted pet door is often the best choice. If you need flexibility and a custom location, wall-mounted may be the better option. If you want convenience without cutting into your home, sliding glass inserts are a great alternative.

The right decision depends on your home layout, your pet's needs, and how permanent you want the installation to be.

Making the Right Choice Matters
A pet door should feel like a natural extension of your home—not an afterthought. Choosing the right installation type ensures better performance, convenience, and long-term satisfaction.
