Ugh - don't cover it up. But, then again I have hardly any window treatments on my first floor. I'm thinking that someone ringing your doorbell at 10pm is a rarity - otherwise put a no soliciting notice up, make sure no valuables like car keys or purses can be seen through the window and embrace not having a house like an old person with every window covered

. Plus, you have a dog - that'll scare any nefarious minded folks!
