Product Details

Product Details


This cover is made for pet door owners who want the convenience of an existing pet door without feeling like the opening is always available after hours, especially in homes where the pet door sits at an easy to reach exterior location.

What changes when it is closed
A pet door flap can be the right choice for day to day access, but it can also leave a lingering concern when everyone is asleep or away. Closing and locking this steel cover puts a solid barrier in front of the pet door so the opening feels intentionally secured rather than simply “flap closed.”

How it works in real use
When pets need access, the cover can be left open so the pet door functions normally. When you want the opening locked down, the steel door swings shut and the combination lock is engaged, and access requires the code you set. The bolts securing this cover in place cannot be removed from the outside, presenting a strong deterrent for any potential intruders.

Fit approach and size selection
The cover is offered in three sizes and is chosen by selecting a size that is larger than the pet door frame it will surround. Because it is designed to cover the opening area rather than match brand specific parts, it tends to pair well with many pet doors commonly purchased in the US when sized correctly using the manufacturer size chart (see Sizing & Fit).

Built tough in the USA
The Watchdog security cover is designed for your confidence and ease of mind, built of high quality materials in the USA.
