Yeah...and your little dog is also unlikely to kill if it does bite. Why does the size of our breed really surprise people when they get asked these types of questions?
Think about it, a terrier can "go off" and bite someone and it probably won't do that much damage, and is highly unlikely to kill a human before someone intervenes, or the victim is able to stop the attack themselves. A GSD? One bite could be all it would take, as they can easily reach the neck of a human adult, never mind a child.
I swear, I either see the "why are people scared of my dog?" Or the "why don't people ask to pet my dog?"
What, in your opinion, is the best way to approach a dog? Or how should someone act around a person who owns a dog that is known to be a powerful and in a sense "dangerous" breed?
