Hold up.
WHY is the assumption that the poster did the deed? Maybe the OP did, maybe they didn't. It's not uncommon for dogs to be re-homed, rescued, etc........
I don't disagree with anything you said, but why would you assume from the get go that the person asking the question HERE of all places is the one responsible? You will have your reasons for wording it like that, I'm sure, but maybe results of such discussions would be different if a bit more care was taken in how things we say are worded?
