Willow spends most of her post-walk evening trying out different spots to sleep. You see her sleeping under your footrest on the couch, next thing you see her on the loveseat, curled up on the left side. You didn't see her move. The next time you glance she's on the right side of the loveseat. Hmmm. Next time you look, she's in her crate right across the room, you never saw a thing. And so it goes, on the couch beside me, on the col kitchen floor, by the front door and on and on it goes. I never see her move, she's just elsewhere every time I check. We dubbed her "sleep ninja" and I think it fits. I don't know where she got her training or if it's a regular Sheltie trick.
