#13 The best thing to do is go to a dog school together. Here the dog can learn to deal with other dogs.
#14 In addition, you should train a strong dog like the Rotti consistently from the start.
You have to make it clear to the dog that you are the "leader of the pack" and that he will submit to you independently. While Rottweiler is known for his fearless nature, he is still sensitive to punishment.
