Dobermans are particularly good at spotting potential dangers and are naturally inclined to excel at tasks for which they are bred. They are also very alert, which helps them learn and remember many commands.
However, Dobermans need a lot of space like a big yard or nearby open areas because they are very active and love to move around.

These dogs are very smart and learn quickly, but their endless energy and strong desire to work can make them a handful. They are loyal and affectionate with the right owner, but if they don’t get enough exercise and mental stimulation, they might start causing trouble.

They were originally bred for stamina and endurance, so they need plenty of exercise. If you don’t have a large fenced area for them to run freely, you’ll need to ensure they get enough physical activity.

Ultimately, choosing the “smartest” guard dog depends on individual needs and commitment to training.
