Leader

The dog is indeed a faithful animal.  This dog was leading the way.  Is the dog a leader too?

No, if you look at the human leaders.  The human leaders bark a lot.  They also lead from the front. 

But not the way this dog was doing.  It was clearing the way for the cart. 

Clearing the way for the follower - that's what leadership is about. 

A leader should be a dog.  Faithful.
