Dog doors are a great idea if utiiized properly.

When I am not home, the dog door has a metal plate that slides over the opening. Nobody that should be in is out, and no one out gets in.

I hope you have a positive latch on it. Many do not.

The people I know that have doggie doors, have them so they don't have to come home and let their dogs outside for potty breaks. You couldn't give me a doggie door because I have heard too many stories about unwanted
creatures coming inside your house, raccoons, snakes, skunks, squirrels and in one case, a skinny drunk human.
