Butters assimilating quickly

My friends have gone to a tropical beach for the week, which means I get a second dog for a few days. She has been here many times before (most recently on Saturday), so she knows the drill. Still, five minutes after her people left, Butters seemed resigned to never seeing them again:

By the time I woke up this morning, however, she seemed to have settled in just fine:

Walking the two of them together in this cold doesn't actually work, however. Butters hates cold weather; Cassie loves it. So Cassie wound up dragging Butters for half of this morning's walk, making all three of us miserable. After lunch I'll walk them again...separately.
