That's why I now turn the lights on at night when walking through the house.
. I had the same problem with Brandi when I crated her, she would poop right in her crate and smear all over the place. I switched to the expen same thing. I finally said screw it and let her roam the house. She use to poop all over the place but now at least she poops in close proximity to her potty pads which I can live with. Sometimes she poops on it, other times she poops beside it but she no longer poops wherever she feels like it.
It took some patience and persistence but eventually she learn what area to poop in. So now when she poops, I just pick it up with a tissue and flush it. She is so close to the potty pad I don't have the heart to get her to be perfect. Also her poop is so small, it doesn't really bother mean. Now my friends 120 boxer, pitbull mix is another story. Her poop alone is about 10 lbs. No way I'm picking that up!
