Paul, here is a reply from a greyhound discussion board.
"hi staci,
we adopted a very shy, insecure grey about 15 months ago
patience yes, but we need more!
"new" dogs have trust issues, we smothered our new grey with love........it takes
months to develop this bond.....but it will come!.......you will see vey subtle
changes
at 3, 6, 12 months and beyond, sometimes it takes longer, but you are in it for
the long haul. also the more time you can spend with your best friend the better,
also read as much as you can about this breed...let us know what happens ....at,
