I think it's funny how each dog shows a different flower preference. With Grace and Macie, it was peonies. They were irresistible and joint garden raids were always being planned when the peonies were in bloom. Grace also loved dandelions--I remember her teaching Brier how to tell the really sweet, ripe blossoms from the too-ripe or not-ripe-enough ones, and how to neatly nip off the flowers when they were just right!
Lili's paws down faves are the spiderwort, though.
I can't say she's 'being trained', Reg, but I think she must've subscribed to some self-help program to bone up on her technique.
