I have a big dog and I want a dog door, but I worry sometimes about safety—both from burglars and sneaky animals (I don't wanna come home to a squirrel in my living room). Anybody have recommendations for the best dog doors out there?
Yes, some can come equipped with locking mechanisms: https://www.petprosupplyco.com/products/plexidor-pd-wall?variant=1247287667&gclid=CjwKEAiArbrFBRDL4Oiz97GP2nISJAAmJMFauWT87bsv4LGl-joCYSv0Y5W (https://www.petprosupplyco.com/produc...)bH1AA7KtIdRnMnSKhRoC65HwwcB

My dog door recommendation would be to only keep it open while you are home, as long as you have a strong fence. A lot of issues can arise while you're gone -people, fence issues, other animals, etc.
Both of these sites feature great and thorough comparison charts for various types of doggie doors. Hope this helps provide you with more information and some insight on which will work best for you and your pup!
