You want your dog door to give easy access to your dog - but not to anyone else!
Watchdog Security Pet Doors are steel covers for dog doors that secure them against unwanted access.
The covers are made of 12-gauge steel and include a combination lock. 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.
