A rottweiler could be a good choice for a first time dog owner but it is important to learn about each dog breed before adopting one. If you are adopting a puppy, it will be your responsibility to train the dog to behave. If a dog is not trained well, the dog can be a danger to a family or to strangers that come into contact with a dog.
Rottweilers can be very protective dogs so it is important to know this before you adopt one. They can also be very loyal to the owner.
