It went from being a bit crazy and disappointed to harassment a few dozen contacts ago.
Do what is right for the dog, that is your responsibility. Her child's hopes are her responsibility. And getting his hopes up and then not getting what he wanted is good practice for life in general, but it is also a lot easier to explain to a kid that the dog had something going on with him, and is not the right dog for them, than it is to explain why the dog bit him or mauled him, or needs to be euthanized because it went after one of his friends.
I think if anything, it shows that you are pretty long-suffering not to have called the police and made a complaint about the lady. She's crazy to have called you that many times. That is totally nutso, and I would be worried about such a nutty person retaliating in some way.
