Back in the day we had 1000 sheep on a hilly 1000 acres in OzI saw a herding presentation done with Suffolks and Australian shepherds, it was super cool how they moved the flock. Err, herd. What's a group of sheep called?
My father and I would bring them out of the hills on horseback with 2 dogs - a kelpie and a border coller (the Australian shepperd is not Australian BTW)
The dogs were amazing. They did the work of 5 men.
The best part was in the wool sheds. The dogs would herd from on top of the sheep's back.
