And when I say used, I mean USED!
What's my secret? Slipcovers and time-outs. I don't think I'd dare to have white furniture without them being slipcovered. They get washed about once a month. I could do it more often but laundry is already an issue around here.
I still battle this little innocent-looking face to not use the walls as his canvas. But for that I just use soap & water or Mr. Clean Magic Eraser... and time-outs.
Then there's Cooper the dog. He sneaks on this couch to not miss a thing going on outside.
He doesn't really "sneak" since, as you can see, he does it right in front of me as I take this picture. But it's not something he does when I am home. I've yet to figure out how to solve this one.
