Burglars aren't stupid. They make a living doing bad things to people's houses and belongings, and they sell them for about one tenth of what they're worth. So they have to do three or four a day.
Burglars and bad guys don't like noise. Silence is their friend. They don't want to see lights. They don't want to see noise.
I myself don't like doggy doors. It's just another opening for someone to get in. Even that small? Even that small.
A size 8, size 9 boot, one kick and this door comes open. If you have metal frames and she does have a two-inch dead bolt, you'll have to kick in four or five times, make a lot of noise to come in on a metal frame.
So don't have big bushes in your front yard where crooks can easily hide behind? Absolutely. But especially the back of the house and side of the house.
How fast can a crook get in and out of a house? How fast can you kick a door open? That fast.
