Interesting conversation. This is the way I look at it. Some people might get upset, but I'm just being honest. I would not personally adopt 'powerful' dogs from a shelter if I had young children. When I say 'powerful' I just mean a dog that has a very strong bite force. Simply because you don't know the exact history and because of the potential damage it could do. Again that's me and just the way I see it. You just don't know. If the dog doesn't have the capacity to due tremendous damage than that's another story.
