Nesting
Barley, a dog, has managed to bundle herself up a big in a comforter.
As much as Barley wants to stay close (as described in a previous post), she has her limits. So whenever I’m doing something mildly vexatious (using the vacuum cleaner, running the shower, etc.), she usually takes refuge in the bedroom and wiggles her way into a comforting ball. She definitely doesn’t understand how one would, mechanically, get under the covers, but she manages to pretty effectively rumple things around herself when she wants to comfort herself with some coziness.
