If by "pestered" you mean that the dog approaches you uninvited, then you have a fair point. If however, as I suspect our friend DH meant, you mean the dog just happens to be in your path (albiet moving towards you) then IMO you don't.
Thinking about it I'd guess I've met a good many dogs over the years when out running, I'm struggling to remember the last time a dog I met showed any interest in me at all. You get the odd juvenile that wants to be friends, and from time to time one shoots off after a squirrel and nearly takes me with it but that's about it.
I can only recall ever having been bitten once. I wasn't terribly happy about it at the time, but I was pragmatic and well balanced enough not to see that as the green light to launch a one man crusade to eliminate them from the face of the planet. It was after all - one dog in almost 50 years of coming across them on a daily basis (man and boy as they say)
Dogs exist - love 'em or loathe 'em they're a fact of life - they're unlikely to be uninvented in the near future.
