Does anyone know for sure if this is true or not? The Rottweiler is a centeries-old breed. The Doberman is a more recent breed. The Doberman was "created" by mixing a Rottweiler (for protection) a Spanish hunting dog (for agility) and a Greyhound (for speed). I know the Doberman has Rottweiler and Greyhound because you can see it, but what kind of hunting dog was used?
