Sheep shows gratitude to the dog after saving them from a wolf attack. 
Discussion
The sheep roll their eyes at the dog. When he barks they jump in fright, sneering at the unpredictable impulsive behaviour. They piously stand in groups gossiping about the dogs nasty habits. Sniffing gross places and eating disgusting things. So repulsive.
Every once in a while a sheep sees the dog doing what it cannot, the raw bravery and aggression in service of the herd.
Sometimes orthodoxy must be broken for sheeple to catch a wake up.
Dude. I am going to write a piece.
