Watchdog Security Pet Door Cover | Locking Steel Dog Door Cover — Large, X-Large & XX-Large

Your pet door gives your dog freedom — but an unlocked dog door is also an open invitation. Intruders know a pet flap can be pushed in, lifted, or crawled through. Raccoons learn to lift magnetic flaps from the outside. Stray cats and wild animals wander in while you sleep. A plain plastic flap locks nothing and nobody out. The Watchdog Security Pet Door Cover fixes that: it is a patented, locking 12-gauge steel security cover that mounts over the pet door you already own, turning your dog's doorway into a locked steel barrier whenever you want it closed — and it is made in the USA.

A Locking Steel Cover for Your Existing Pet Door

First, what this is — and what it is not. The Watchdog is a pet door security cover only. It does not include a pet door, flap, or tunnel. It mounts over your existing door-mount or wall-mount pet door and locks down over it. Leave the steel cover open while your dog comes and goes as usual; then, at night, while you are at work, or on vacation, swing it shut and engage the built-in combination lock. No key to lose and no flimsy plastic slide-in panel — just solid steel between your home and everything outside it.

12-Gauge Steel Security, Built in the USA

Every part of this locking dog door cover is steel: the frame, the cover door, and the hinges are all formed from 12-gauge steel, with welded barrel hinges and a frame shaped to resist prying. The mounting hardware is tamper-resistant — the bolts cannot be removed from the outside — and all mounting hardware is included. The finish is a clean white powder coat (the only color offered), and it can be painted over to match your door, trim, or siding. The cover installs on the outside of your home, which is the recommended setup; it can also be mounted inside if securely fastened. The cover door lifts off its hinges for separate storage whenever you want it out of the way. Patented design, made in the USA.

Why dog owners add a security cover to a pet door

Is your dog's door the weakest point in your home security? Is your dog letting himself out at 2 a.m.? Are raccoons treating your flap like their own front door? A locking pet door cover gives you control: home security against intruders, a real barrier against raccoons, strays, and wildlife, the freedom to keep your dog safely in — or out — on your schedule, and peace of mind when the house is empty.

Three Sizes — Large, X-Large & XX-Large

Watchdog sizes are matched to the pet door you already own, not to a breed chart. Is your dog using a big flap several times a day? Then start by measuring the exterior frame of your existing pet door, and choose the cover whose frame is larger than your pet door's frame:

• Large — fits pet door flap openings up to 11" × 17½"; cover exterior frame 15½" × 21½"; fits existing frames up to ½" deep
• X-Large — fits flap openings up to 12" × 24"; cover exterior frame 16½" × 28"; fits existing frames up to ½" deep
• XX-Large — fits flap openings up to 16" × 26"; cover exterior frame 20½" × 30"; fits existing frames up to ½" deep

Endura Flap owners: your Medium takes the Watchdog Large, your Large takes the Watchdog X-Large, and your Extra Large takes the Watchdog XX-Large. (The Watchdog does not fit Endura Flap Small or XXL pet doors.)

Door Mount or Wall Mount — Opens Left or Right

Choose Door Mount if your pet door is installed in a door, or Wall Mount if your pet door passes through a wall. The price is the same either way — it depends only on the size you pick. Then choose your opening direction: standing outside your home and looking at the cover, choose Left for hinges on the left side, or Right for hinges on the right side, whichever clears your trim, siding, and swing space best.

Frequently Asked Questions

Does the Watchdog cover include a pet door?

No. This is a security cover that mounts over the pet door you already have. The pet door itself is not included.

Will it work with my sliding glass pet door insert?

No. The Watchdog cover fits door-mount and wall-mount pet doors only, and it does not fit Ruff Weather brand pet doors.

Can I paint the cover to match my house?

Yes. The cover comes in a white powder-coat finish — the only color made — and it can be painted over to match your door or siding.

Where does the cover install?

On the outside of your home is recommended. It can be mounted inside instead, as long as it is securely fastened, and the cover door can be lifted off its hinges and stored separately.

How does my dog use the pet door with the cover on?

Just leave the steel cover open whenever your dog should have access. Close it and engage the combination lock whenever you want the opening sealed.
