The shearing sheds were filled to capacity, old Shep despite his arthritic hips, virtually blind and deaf as stone managed on his own to convince the free roaming Marino's that Flockdown was much safer than risking their lives on the hills where the Lone Wolf fairytale could become a reality at any time and while in The Pens it was an opportunity for dipping injecting and branding lest they got lost in their newly zoned restricted grazing areas.
( Moral )
So, if all the other sheep were aware from the beginning that Shep was not Pavlov’s Dog, then why did they think they needed a Bellwether???
