If one is good, two has to be better - right? Yes, that is the thinking that led to Cassie... the smaller golden. She was located online - and shipped from Rochester. Sam decided that if he didn't look at her - she would 'go away'. Two weeks into this - he looked pleadingly at us "She IS going home, right??".
She played Alpha dog almost immediately - stradling Sam's head/shoulders - so that he had to peek out from below... but he didn't mind. Then she became his shadow - and it's been that way ever since!
