Rottweilers are strong, brave, determined, and smart. However, they are also calm, and can be downright tender with their family. They are natural guard dogs, and may become over protective of their family if not socialized early. They are intelligent and easy to train, but this training should not be taken lightly, as they are enormous dogs and if left up to their own devices, can become quite destructive and dangerous. That being said, if they are well trained (which shouldn’t be all that tough), they are some of the most loyal, dependable, and sweet dogs. .
