Heavy Duty Insulated Wall Mount Dog Door

Give your dog the freedom to come and go without waiting for someone to open the door.

The Happy Doggo Wall Mount Pet Door creates a dedicated entrance through an interior or exterior wall, allowing pets to independently head outside for bathroom breaks, playtime, or fresh air.

Built with a durable metal frame, telescoping wall tunnel, three-flap system, and secure closing panel, it's designed for everyday use by dogs and cats weighing up to 100 lb.

More Freedom For Them. Less Door Duty For You.

Dogs don't always want to wait.

Whether they need an early-morning potty break or want to head into the backyard while you're working, a dedicated pet door gives them more independence while reducing how often you're opening and closing the door yourself.

Install it directly into a compatible wall and create a permanent pet-friendly entryway.

Give Your Dog Independent Outdoor Access

No more waiting beside the back door.

Once properly installed, your dog can move between indoor and outdoor spaces without needing you to open the door every time.

It's particularly useful for:

• Backyard access
• Potty breaks
• Active dogs
• Multi-pet households
• Busy pet parents
• Dogs that frequently ask to go outside
• Homes where a traditional door-mounted pet flap isn't ideal

Triple-Flap Protection

A basic single-flap pet door can leave more exposure between your home and the outdoors.

This model uses three flap layers to create additional separation.

The multi-flap design is intended to help:

• Reduce drafts
• Improve the barrier between indoor and outdoor air
• Limit direct exposure to wind
• Maintain a more comfortable indoor environment

It's a practical upgrade for owners who want pet independence without relying on a basic single-layer opening.

Built For Everyday Use

Your pet door may be used several times every day, so durability matters.

The frame combines steel and aluminum-alloy components and uses a metal construction designed for repeated use.

A metal closing panel is also included, allowing you to close off the opening whenever you don't want your pet using the door.

Telescoping Wall Installation

The integrated tunnel adjusts to accommodate compatible walls measuring approximately:

4¾" to 7¼" thick

This creates a finished passage through the wall rather than leaving the internal wall cavity exposed.

A cutout template and step-by-step installation instructions are included to help guide installation.

Spacious Opening For Larger Pets

The pet opening measures approximately:

10¼" Wide × 16¼" High

The manufacturer specifies the door for pets weighing up to 100 lb.

Pet weight alone does not guarantee fit, so always compare your dog's shoulder width and height with the opening dimensions before ordering.

Lock Access When Needed

There are times when you may not want your dog going outside.

The included metal closing panel lets you block the pet door when necessary, giving you greater control over when the opening can be used.

Useful for:

• Overnight access control
• Bad weather
• Yard maintenance
• Travel
• Keeping pets indoors temporarily

Measure your pet from around the shoulder area to the floor.

The flap opening is approximately 16¼ inches high.

Step 4 — Measure Your Wall

Confirm that your wall construction is suitable and falls within the supported 4¾–7¼ inch thickness range.

Happy Doggo Installation Tip

Measure twice before making any wall cut.

Check both your pet's dimensions and your wall thickness, and make sure the installation area is clear of electrical wiring, plumbing, and structural obstacles.

After installation, keep the flap open initially and encourage your dog through with treats. Gradually introduce the moving flaps once they're comfortable using the opening.
