The best way to secure a pet door is with a Watchdog Security Locking Pet Door Cover.

Are you worried about the security of your home with an unsecured pet door, or worse, have you avoided installing a pet door because of the possible security risk? Watchdog Security Pet Doors has developed an answer. You will never have to worry about the security of your pet door again.

This product is a heavy-duty 12-gauge steel frame and cover with a combination lock that goes OVER your existing pet door, on the outside of your home. When you want the dog to have access, the Watchdog Security Pet Door Locking Cover can be left open. When you want security, the steel door can be closed and the combination lock engaged. Now your pet door is secure and no longer a security risk. Simple!

Please Note: The Watchdog Locking Pet Door Cover does not come with a pet door. It goes over an existing pet door, to secure it. The images showing a pet door with the Watchdog Security cover are only to demonstrate how well the cover works with existing pet doors.

Please note also that Watchdog Security Covers DO NOT work with pet doors built into sliding glass door inserts. Choose from "Wall" or "Door" mounts when purchasing.

Key Features
  • Currently available ONLY in white; the cover can be easily painted over to match a wall or door.
  • The combination lock is set by you to a unique security code. Don’t forget it! There’s no way to unlock this steel cover without that code.
  • There is a special version with special bolting hardware for installation on a (human) door and another version for installation on a wall.
  • The Watchdog Security Pet Door Locking Cover is securely fastened with heavy hardware designed for door or wall use.
  • A durable UV powder coated finish resists scratching, rust, and the elements.
  • When you want your pet to have access, you leave this security door open. You have a choice of opening directions. "Left" means that the hinges are on the left when outside looking at the security door. "Right" means that the hinges are on the right side. However, this neat design allows you to lift the steel cover off its hinges when the door is open so you can set it aside entirely. When the door is closed, the cover hinges are locked in place by the steel frame.

Watchdog Pet Door Locking Cover Installation Guide

Note that the manufacturer recommends that the door be bolted onto the outside (not the inside) of your door or wall for a few reasons:

  • Mounted outside, the potential intruder is immediately confronted with a steel barrier and is likelier to not even attempt anything. Those bolts, by the way, can’t be removed from the outside.
  • The outside of a wall is typically much stronger than the drywall interior side. It’s better to have something sturdy to bolt into. Of course, if you can hit the studs from the inside that’s going to be sturdy as well.
  • Because of the typical locking cover on the inside of the pet door, more clearance is needed for the steel door. There may not be enough room for an inside install.


Plan on mounting on the outside if a wall installation and either side for a solid-core door provided you have clearance for the pet door locking cover on the inside install.

For vacation homes and long vacations when you can just lock it and forget it, this solution just can’t be beat.


Below is a sizing chart listing which of the most popular door manufacturers the Watchdog Security Pet Door cover fits. You may identify the pet door you own to see if it is on this chart. Otherwise, simply measure the dimensions of your door to see if it fits within one of the 3 door size parameters. Most pet doors purchased in the USA will fit with one of our 3 sizes.

Ask a Question
  • What does the other side of the door look like? I don’t see any pics of that.

This is only meant to mount directly on the exterior of your existing doggy door, so the back of it is flat and will be flush to whatever surface you mount it to.

  • How heavy is the xxl door?

    Hi, here's the weight of each Watchdog security pet door: Large: 13 lbs, XL: 18 lbs, XXL: 23 lbs. Thank you!

We offer free shipping on orders over $99.

We know that high-quality pet care equipment is heavy and we do not want shipping costs to be an issue when you buy from us. That’s why on most orders over $99, shipping is 100% free!
Please note that in some specific situations, unfortunately, we cannot offer free shipping. These include:
  • International orders
  • Orders shipped outside the contiguous United States
  • Some brands such as TK, Rhino and Owens have a higher minimum order amount to qualify for free shipping (their items are much larger and heavier than typical orders)
  • Very large items (e.g., kennel fences) that must be shipped via large industrial freight trucks, when shipped to a non-commercial address or an address with limited access. (On these we still cover the shipping costs, while the customer pays the freight company’s additional delivery fee – usually $70 to $80 on most orders)
We want to make sure you have all the relevant shipping cost information when placing your order. So if you have any questions, please get in touch!
Write to us at, call us at 1-855-PET-PRO1 or you can message us on Facebook!

We pride ourselves in maintaining excellent communication between our suppliers and our customers.

Order Confirmation

As soon as you place your order you will receive an order confirmation e-mail and we will immediately notify the appropriate supplier to begin processing your order.

Item Availability

While we almost always have the most up-to-date inventory information, there are rare occasions in which an item may be unavailable or on back-order. If the item is unavailable, we'll let you know and give you the option of receiving a refund or ordering a similar item. If the item is on back-order, we will contact you directly and provide you with an updated shipment date. From there you may either choose to cancel the order or continue with the updated shipment date. Certain made-to-order items may have a longer than normal lead time. If this is the case, the lead time will be specified on the product page.

If you would like to confirm the availability or potential lead time of an item prior to purchasing, please email us at or call us at 1-855-PET-PRO1.

Delivery Estimates

For standard orders we normally ship within 1 to 3 business days and you can expect to receive your goods in 3 to 10 business days total. Please allow 1 to 3 weeks if your order is large and must be shipped by LTL freight truck (as opposed to standard carriers such as Fedex or UPS). For custom orders that require fabrication by our manufacturers, please allow 2 to 4 weeks for fabrication and shipping. Please note that some items may either be on back order with our manufacturer or require more weeks for fabrication and lead times may be longer than 4-6 weeks (especially larger metal items) - these will typically be flagged on our product pages for that product if that is the case. If you are not sure about shipping times for your product or require a rush order, please contact us and our team will check with the manufacturer to confirm shipping time for your specific product or variant. In all cases, to ensure we meet your shipping time needs, please just contact our team at or 1-855-PET-PRO1.

Shipping Confirmation

We ship from warehouses all across the country, depending on the item(s) ordered and your location. Depending on the physical size of your order, items will ship either by freight or a regular parcel carrier such as USPS, Fed Ex, or UPS.


LTL (less-than-truckload) Freight is used when shipments are 120 lb+ or for oversized equipment, which results in a truck with a large container delivering your order. Our freight carrier will contact you once your order makes it to the distribution center closest to the delivery address specified, and set up an appointment time for delivery.

Pet Pro Supply Co. Free LTL Freight Shipping - Curbside Delivery

Our standard Free Freight Shipping option for LTL deliveries is curbside, which is to a delivery to a Commercial Address and does not include a liftgate. If your order is to be shipped freight, you will have the option to specify whether the item will be delivered to a Residential, Limited Access, or Commercial address. If there is no option to select a shipping location, then this cost is already included in the price.

We strongly recommend adding the optional Liftgate for all deliveries to locations without a loading dock or forklift.

Freight Delivery Locations

This option specifies whether the delivery location is a Commercial, Residential, Residential Business, or a Limited Access address.

  • Commercial - These addresses are those defined by our freight carriers and/or zoned by local municipalities as commercial sites. Typically these addresses are zoned as commercial real estate or are used exclusively for business. Most commercial sites have tractor-trailer access and a loading dock.
  • Residential - If the address used a residence, select this option. This includes Apartment/Condo complexes and dormitories.
  • Residential Business - Any business being operated from a home, apartment, or other dwelling where people live on the premises is considered to be a Residential Business.
  • Limited Access - Locations where deliveries are restricted, limited, or very far from a distribution center. Examples Include:
    • Place of Worship
    • Restricted Areas - Secure Research Facilities, Military Bases/Installations, Correctional Facilities, Government Buildings
    • Farms, Ranches, and Rural Areas
    • Recreational Areas - Camps, Parks, Fairs, Carnivals, etc.
    • Individual Storage Units
    • Sites - Convention Centers, Construction Sites, Mines
    • Schools and Universities
    • Commercial establishments not open to the walk-in public during normal business hours

Freight Liftgate

A liftgate is a hydraulic lift that is attached to the back of a truck that can lower freight to ground level. Freight carriers prevent their drivers from assisting with the unloading of heavy equipment other than using a liftgate to ground level. We highly recommend any delivery address without a loading dock, select this option.

However, please know that for certain very long items, such as Kennels over 6' in length, a Liftgate will not be able to bring the entire order down to ground level. Please have the necessary manpower available to receive your items with limited delay to the driver.
