Rottweilers were originally bred to be hard-working, protective dogs. These powerful dogs have incredibly strong jaws and excel at police work, herding, and watch-dogging, as well as obedience. Rotties are exceptionally smart, which makes them easily trainable, and they are usually very happy, goofy dogs. They tend to be protective of their families, but make loyal and affectionate pets. Rottweilers are large dogs, weighing in on average at around 100 lbs. fully grown, and are fairly active and like to exercise.
Males and females of the breed may differ in personality. Males are quiet yet vigilant, always on the lookout for danger, while females tend to be easier to control, as well as more affectionate.
The Rottweiler descends from a mastiff-type dog called the Molossus. There is great evidence that linking its ancestry with one of the drover dogs indigenous to ancient Rome.
