Napping pack

I feel like D thinks of T as a littermate (size?  behavior?  who knows...) since he plays with her like another puppy, steals toys from her, gnaws her ears, and tries to sleep as snuggly as possible whenever he can.  She is OK with him doing the latter when he is chill and sleepy, not such a fan of the rest but we are working with him. :)  So today he decided to join her in her under-table 'den' for a nap and she let him do it without getting up and moving elsewhere.
