Do you leave lights on for your dog if you go out at night?

Well, contrary to most of us, my mom will leave the lights off. And her reason would be so that people who attempt to enter our homes will not be able to see them, especially since 2 of our dogs are black so they are indeed happily blending in the dark while we are out. So far, they do not have qualms or concerns being left without lights. I guess that's because they can see much better than we can as their eyes are more reflective than ours (That's why when we take their pictures, sometimes the photos come out with shining eyes).

I like leaving the lights on when I leave but I always come home with them ending up turned off by the person who's arrived before me.
