I don't think the dogs would be immediately dangerous to humans, IF handled correctly...although if I had young children I wouldn't trust them to be around them (children can play too boisterously (sp?) with dogs and some dogs have an intolerance for it).
However, I wouldn't re-home them in a home that has any other family pets.
A much more ideal 'use' of these dogs (for lack of a better word) is as guard dogs, but not for family home.
More words here is more words.
