God, that it is the saddest thing, ever.
It breaks my heart that you love dogs so, yet have none.
Have you considered adopting an elderly dog?
They have a very hard time finding homes because everyone wants young, active cute dogs, not old couch potatoes who just like a meal and soft blanket.
:(
Would I ever completely trust her? No. But I would hate to see what would happen to anyone who ever threatened him or his children. As to his wife? I dunno, but I don't think the dog would have to worry about what happens to anyone intending to hurt her.
