Rottweiler

The Rottweiler were known in German as Rottweiler Metzgerhund, meaning Rottweil butchers' dogs. Although still used to herd stock in many parts of the world, Rottweilers are now also used as search and rescue dogs, as guard dogs, and as police dogs. The Rottweiler is one of the oldest of herding breeds and history possibly dating back to the Roman Empire. Rottweilers are a powerful breed with genetic guarding instincts. Irresponsible ownership can result potentially dangerous behaviour. Study published in 2008 found that male rottweilers have higher confidence, sharpness, and defense and play drives than females.
