The Rottweilers' size and bark will discourage most intruders, yet he will learn to recognize your friends and receive them cordially. The Rottweilers instinct to protect those he loves becomes very apparent as he matures. However, problems can arise quickly. Strangers must never come into your home or garden unannounced. Roughhousing with your Rottweiler should be avoided.
Rough play encourages aggressive behaviour.
People expected to be in contact with the dog while you are absent should be well known to the dog. Although Rottweilers are unlikely to bite without provocation, being cornered and held by one of these dogs is very unnerving. A large garden with a six foot fence is ideal, but Rottweilers have been successfully kept in large flats. A garden is essential if you are getting a puppy or young dog. A garden will help keep the dog exercised and reduces boredom, possibly preventing some destructive behaviour.
