• Medium flap opening measures 8 1/4 in wide x 12 1/4 in high (21 x 31.1 cm) — sized for dogs up to 40 lb.
• Telescoping tunnel fits walls 4 3/4–7 1/4 in thick — accommodates a range of wall depths.
• Double-flap design provides weatherproofing and energy efficiency — helps limit exposure through the opening.
• Durable plastic frame won’t rust like steel alternatives — suited to an installed wall opening.

When a pet door cannot be installed in a human door, this wall-entry design creates a dedicated route between indoors and outdoors. Cats and dogs can come and go for potty breaks or play time without waiting for someone to open a door. It is made for installation in interior or exterior walls, with the tunnel connecting the two sides of the opening.

Will the medium PetSafe Wall Entry Pet Door fit my dog?

The medium flap opening is 8 1/4 in wide x 12 1/4 in high (21 x 31.1 cm), and the size is intended for dogs up to 40 lb (18.1 kg). Compare your dog’s fit with the opening dimensions when choosing this size; the weight guidance and flap measurements describe the medium option. The door is also suitable for cats, and PetSafe offers this wall-entry door in three sizes.

• Medium size for dogs up to 40 lb.
• Flap opening: 8 1/4 in wide x 12 1/4 in high.

What wall thickness does the telescoping tunnel fit?

The included telescoping tunnel adjusts to walls from 4 3/4 to 7 1/4 in thick (12.1–18.4 cm). For a wall thicker than 7 1/4 in, a compatible tunnel extension kit is available separately. The door is designed for interior and exterior wall installation, making it a practical option when a door-mounted pet entrance is not possible.

This is a do-it-yourself installation project: a cutting template and step-by-step instructions come with the door. Use the template as part of preparing the wall opening, then install the door and tunnel according to the instructions.

• For walls thicker than 7 1/4 in, a compatible extension kit is sold separately.
• Designed for both interior and exterior walls.
• Cutting template and installation instructions are included.

How does the PetSafe pet door help manage drafts and access?

The door uses a double-flap design for weatherproofing and energy efficiency, while the slide-in closing panel adds insulation when your pet door is closed. The panel also gives you a way to control when your pet can pass through, rather than leaving the opening available at all times.

The frame is made from durable plastic that will not rust like steel options, and its PVC construction withstands UV exposure. Together, the double flaps and closing panel provide the door’s stated weather and insulation features; the panel can be put in place when you want to restrict access.

• Double flaps provide weatherproofing and energy efficiency.
• Slide-in panel adds insulation and controls access.
• PVC frame withstands UV exposure.

The PetSafe Wall Entry Pet Door is best suited to households that want cats or dogs to have independent access through an interior or exterior wall, especially where installing a pet door in a human door is not an option. Choose the medium size for a dog within its stated weight guidance, and compare the flap opening and wall thickness with your home and pet. Its medium opening, adjustable tunnel, double flaps and closing panel make it a wall-mounted route for pet access with a way to close the opening when needed.
