Are Dobermans hard to train?

No. The Doberman was bred specifically for high trainability. However, this doesn’t mean a Doberman puppy is easy to train. Many of the temperamental attributes that make the adult Doberman so wonderful - such as intelligence, obedience, and sureness - work against you in puppy form.

When you begin training a puppy, you’re matching your will with the puppy’s will. One day, though, that little puppy will suddenly realize something. When this happens, training suddenly becomes much easier.

If you stick to consistent training, your puppy will realize that you are simply teaching him the best way to get what it wants.
