Someone on the beardie website I have been frequenting lately posted a link to this video:

Now, as you can imagine, I was slightly put off by the name of the site, but they'd raved this vid so I gave it a go.
It is very sad, but it does have a happy ending. It concerns a little dog who was about to be put to sleep at a shelter. She was unapproachable and savage. One of the people at the shelter decided not to allow that to happen. She saved her from being euthanized and instead called her dog behaviourist friend in.
The video shows the dog being won round. It is really very moving.
