The leading dog

My regular walk on Southampton Common yesterday was pleasant, with a large portion of  dogs taking their human for a walk! I've never had a dog and would  never want one (far two much work and less of freedom). But I do appreciate them when they come to me to say a (doggy) "Hello". Some time ago I learnt dogism: behaving like the ancient wild dogs from which they came, when every dog obeyed the leading, tallest dog. In this case, I am the leader and I hold out a my regal back-of-hand to be licked.
