Pet Door Security! Watchdog Locking Pet Door Cover

Are you worried about the security of your home with an unsecured pet door, or worse, have you avoided installing one because of security? Fortunately, Watch Dog Security Pet Doors has developed the answer. With the amazing Watchdog Security Pet Door Cover, you will never have to worry about the security of your pet door again.

Beginning with heavy duty 12 guage steel, Watchdog builds a frame with cover and a combination lock to fit on the outside of your house. When you want the dog to have access, the Watch Dog 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 liability.

Please Note: The Watchdog Locking Pet Door Cover does not come with a pet door by itself! The images showing a pet door with the Watchdog Security cover are only to demonstrate how well the cover works with existing pet doors. Watchdog Security Covers also DO NOT work with Pet Doors built into Sliding Glass Panels Inserts!

Freight Shipping Information

There is often confusion about how freight works and how lift gate deliveries work. Freight is used when shipments are 120 lb+ or for oversized equipment. Our standard Free Shipping option for freight delivery includes 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 or Commercial address.  If there is no option for Residential or Commercial delivery, then the cost of this is included in the price.

We also recommend adding the optional Liftgate for all Residential deliveries, and any commercial locations without a loading dock.

  • Freight Delivery Location - This option specifies whether the delivery location is a Residential or Commercial address. 
    • Residential - The fact that a business is being operated from a location does not qualify it as a commercial address. Any business being operated from a home, apartment, or other dwelling where people live on the premises is considered to be a residential address. Our freight carrier will contact you to make an appointment before delivery is attempted to a residential address. Residential delivery does NOT include a Liftgate. Liftgates are a separate option.
    • 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. Most commercial sites have tractor-trailer access and a loading dock.
  • Freight Liftgate - A lift gate is just 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.
