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

My husband laughs at me because I turn the lights on outside when it is dark, when our dog goes out to use the bathroom.

I realize that he doesn't need the light to see what he is doing. I think I use it more to see what he is doing and why it is taking him so long to come back inside!

I also think that leaving the lights on when we leave is more for us so we don't have to come back to a dark house!!

We always tell our dog not to have any parties while we are gone!!! LOL
