Everyone has seen a German Shepard around, as they have been bred for law enforcement. If you train a German Shepard properly, then they will turn into an obedient and intelligent animal. That being said, they have a very strong aggressive side, and can snap at any moment if they see a stranger. They are also very big animals, with lots of power and very sharp teeth, and they can therefore hurt children very easily. It is thus very risky to own a German Shepard if you have small children.
