But the sheep don't know these truths, so they move, sometimes they even run wherever the dog wants them to go.
You know where the sheep go?
They go where they can have all their wool taken right off their backs. It's not very smart of the sheep.
Even the dog doesn't have to know more than he has trained and practiced to do.
After all, even if he knew how, he could only use a small part of the sheep.
But it works for the dog. He eats well. It's good for the Shepherd. He makes money.

It's not very good for the sheep. They get shorn. Then they get eaten.
It's called "herd mentality".
