One of the first things you need to consider when thinking about getting a Rottweiler to keep as a pet is whether you are strong enough to be a master and leader of the pack. First and foremost, you need physical strength. These dogs are very big and strong that need a lot of exercise. If you do not have the strength and qualities to control the dog, or even to have the ability to take it for walks twice a day, then the Rottweiler is definitely not for you.
The breed also has a penchant for doing their own thing. Unless you have a very strong character and impose yourself as a leader of the pack, again, Rottweilers are not for you. The breed needs to respect the owner as being the Alpha dog. If the owner cannot step up and be the master of the pack, then the Rottweiler will act out and try and challenge for leadership itself. This could mean misbehavior and/or destructive behavior.
Training needs to be intensive and must start at a very early age. Failure to do this will result in a very rowdy dog which will challenge you and will not obey commands. Though they are big and powerful dogs, they are quite easy to cater for in terms of day to day living. They need daily walks with some ball play, and they also need to be groomed at least once a week. Other than that, they are quite easy to cater to. They love spending time with their family and make really good cuddle buddies for children. They are very loyal and protective of their families and territory.
Rottweilers tend to be very easy going and sociable and will only become aggressive when they or a member of their human pack is visibly threatened. This is also not a trait that can be bred into any dog, it is natural dog behavior.
