Velcro

In case you were wondering, and I know you were, Nikka is made of velcro.

When Lyn came home from day hab, Nikka greeted her by spinning around the room.  This is her normal approach to greeting my sister.  Lyn sat down and the velcro between them took hold.  They stayed like this for over a half hour.  

Lyn may not be smiling, but she is thrilled by Nikka's response to her and just adores the dog.  It is a good thing because the feeling is so clearly mutual.
