The AKC Standard describes the Rottweiler as "a calm, confident, and courageous dog with a self-assured aloofness that does not lend itself to immediate and indiscriminate friendships." Typically steadfast, sensible, and serious (though some are happy-go-lucky clowns!), the Rottweiler tends to respond quietly and with a wait-and-see attitude to influences in his environment.
This muscular dog needs some space and exercise: brisk daily walks, interactive romping sessions, and regular opportunities to stretch out and run. Mental exercise (advanced obedience, agility, retrieving a ball, Schutzhund) is even more important and appreciated.
Rottweilers must be thoroughly socialized at an early age so that their territorial instincts are controlled rather than indiscriminate.
They can be aggressive with other dogs of the same sex, and while many Rottweilers live peacefully with the family cat, other individuals are predatory toward cats.
Most Rottweilers are inclined toward dominance and will test for position in the family pecking order, but they will respect an assertive owner who knows how to lead a strong-minded dog
Overall, the Rottweiler is a splendid, capable companion in the right hands, but without ongoing companionship, socialization, obedience training, and supervision, he is "too much dog" for many households.
