Is it necessary to have a professional trainer to own a properly tempered Doberman?

No, a Doberman owner needs only dedication and consistency to train the ultimate companion. A good training book and some advice from an experienced owner are enough.

Professional training can be helpful in the form of a puppy class. These classes provide the essentials for a happy puppy. They teach the handler/owner the basic commands and how to train them into a dog. These classes also allow the puppy exposure to people, other animals, and lots of strange sights and sounds which are the key to socialization.
