Leader of the Pack

This obliging dog walker let me photograph his pack of ferocious animals. 
They were cute, all walking at the same pace on their little legs, all observing the exact same  separation distance. 
He explained to me that the leader of the pack is the old lady on three legs closest to him. She sets the pace: geriatric tetrapodal. And the others follow suit. 
As I was complimenting him on how well behaved the four of them were, the two little mix-chihuaha-types in the middle started having a go at each other. 
Little yappy dogs are exactly like little yappy kids. Never praise their good behaviour for fear of jinxing it and seeing them return to their true nature in the blink of an eye.
