As bad as I feel about Mitzy it's obvious her problem is much more severe than Mayfly's.  Mayfly is shy with new people but we've been leaving the dogs with Glenna's roommate while we go out running around and guess what?  Mayfly follows him around and hops up on the couch and snuggles up to him!!!>???!  Although he did say that at the slightest sound M&M jump up and run to the window to see if I've come back. 

I think Mayfly may not be as socially crippled as I thought she was!

That is so awesome. I truly in my heart believe when these dogs find good loving homes there is no issue they cannot resolve, I think it comes from a comfort level.
