In PetTalkVille, I, as mayor, would have a herd of specially trained big dogs - maybe Saint Bernards, Great Pyrenese, Irish Wolfhounds, Danes, or mixes of that size - you know, the "too big too ignore" kind. If, by some strange circumstance, an argument broke out, they would gallop off, get between the two or however many people arguing, and start licking faces. There - you try to fight with a washcloth-size tongue washing your face!
