My guess is that a nippy, aggressive border collie would be liked even less but would not be challenged.
There is a reason that herding dogs have a job; it’s because sheep respect them. Unlike sheeple, real sheep are not stupid enough to be fooled. “That is a herding dog! Obey!” “Baaaah, Naaaah” sez the sheep.
“Wear your mask forever! Obey!” “(Muffled) yes, master” sez the now immunized sheeple.
Heheheh you are probably right!
On one hand, it is a whirring, odd, wobbling thing coming at them...
On the other hand with a sheepdog, it is...”WOLVES!”
