She did sleep for a bunch of the night, though woke up at 3am from a nightmare or something, whimpering and whining, and tried desperately to climb into the bed with me. (All the puppy training books I read said that the puppy shouldn't sleep in your bed until the first six months are done, but many said that the puppy should sleep near it.) So I scooted to the edge of the bed, let my hand drop down into her puppy-bed. She curled up around my hand and went right back to sleep.
She's very adorable overall. I got the puppy her breakfast, and she figured mommy must be hungry to, so she carefully brought me bits of kibble, one at a time, and dropped them at my feet.
She still has some panic moments when she realizes all the other dogs are gone, and comes running to me wanting a cuddle, but she's also relaxing a little more. Today's going to be a little more settling in (what the 'first day' should be, since we got back so late yesterday), and thus the schedule's a little less rigid. Tomorrow we'll start more properly following the New Skete puppy acclimation and training schedule.
Claire's also figured out how to get up onto the couch, if she gets a running start from across the room. Right now she's engaged in stalking the wild, fierce chewy rope bone.
