'Calm, confident and courageous, with a self-assured aloofness… an intelligent dog of extreme hardness and adaptability, with a strong willingness to work…' These descriptions give you a good idea of what to expect from an adult Rottweiler who is well-bred and has been raised correctly.It’s important to know that Rottweiler behavior should never include indiscriminate aggression, or appear vicious, ‘sharp’, fearful or nervous (skittish).Rottweilers are very loving, affectionate dogs. They prefer to be ‘where the action is’ and are only really happy when they’re a part of the family.
