A dog cannot be controlled 100% by a human, think about it, dogs have been wild animals longer than they have been domesticated and will have natural agression even if you donn't like to admit it even poodles have natural agression.
I have a huge south african mastif and also a staff and I wouldn't expect them to hurt anyone, they are some of the kindest dogs i've owned. But that doesn't mean i'm going to leave my young nephew in a room with them on his own. ALL ANIMALS are capable of attacking humans but if brought up in a loving home, it only makes this LESS likely to happen, it's still possible.
