Rottweilers are known to be highly protective dogs. While the breed is loyal, confident and generally calm, your Rottweiler will need daily exercise, strict obedience training and early socialization. This breed tends to be domineering and some cannot be trusted around small dogs or cats. A Rottweiler may respond in an overly-protective way if it feels its family is being threatened. Avoid playing aggressive games with Rottweilers. These dogs enjoy being mentally challenged and are somewhat dependent on their owners for happiness.
