I know. There is no disagreement here, and you have taken it very well….possibly better than I as “an apologist” would.
Where we do disagree, is where a dog runs up to you with no malice, but inquisitive (and I accept it’s not always easy to discern). I maintain if you act properly, ie total disinterest, it will quickly be disinterested in you. If however you react, start shouting, waving hands, pushing it or kicking out, in my opinion you increase the chance of prolonging or escalating the situation, including of being bitten.
Which was clearly not the case here. It just bit anyway, and nothing you should have done changes that. The blame is entirely on the dog and owner.
