How to Secure a Dog Door 

We see lots of concern from customers about the security of their pet door; particularly if they need a large dog door. Extra-large pet doors are often big enough for a person to crawl through. There are a number of products on this page for both dog doors and cat doors that increase the security of your pet door. We also have information on locking systems for wall mounts, small dog doors, and electronic doors.
