Shadows
Holly has always been my shadow, normally following me from room to room keeping an eye on what is going on. But she has picked up her own shadow in the last couple of months, Buddy will follow her everywhere (unless there are treats or toys on offer somewhere else) so sometimes my shadow has a shadow. Even when Holly isn't following me, Buddy will still follow her around the living room until she settles somewhere, which takes her longer than it used to because she doesn't appreciate the invasion of personal space that is Buddy.
