The Doberman's ratings describe a dog that was built for a job and still expects one. Ninety minutes to two hours of daily activity is the realistic figure, and a meaningful part of it has to be mental — obedience, tracking, protection sport, agility or serious structured training at home.
Without that, the failure mode is not a naughty dog. It is an anxious one. Dobermans are unusually sensitive for their reputation, they attach very closely to their people, and an under-employed Doberman becomes restless, clingy and destructive at doors.
That sensitivity is also why the training works. Dobermans learn fast, want the interaction and are ruined by heavy-handedness. They are frequently described as velcro dogs and the description is accurate — this is not an aloof breed at home despite the 2/5 with strangers.
The Akita's independence is the opposite proposition. It needs less from you, does not experience an empty afternoon as abandonment, and gives you correspondingly less influence. Its recall should be treated as conditional at all times, and secure fencing is a requirement rather than a preference for both breeds.
