A dog with excellent temperament should not require a ton of socialization, training, or exercise.
A dog of excellent temperament and correct structure should be able to manage a ton of socialization, training, and or exercise.
A GSD of good character should be able to relax in any situation, taken out of the kennel at 9 months, over to a house with strangers including kids, shouldn't matter, the dog should be just fine. He should not go stir-crazy if he is not walked into the ground before being left for the day. That's insanity. A dog should not require being physically and mentally exhausted every day, to have a reasonable expectation for behavior. A dog should not have to be trained every day, or several times a day to learn basic and advanced commands. And a dog should not be losing steam before you are if you give them age-appropriate amounts of exercise.
If any of the above is true, look at the temperament of the dogs, because a GSD should be able to live in most conditions, with most types of owners, and adjust to the activity levels, and training levels of the owners.
It should not be rocket science.
I am a fan of the West German Showlines. I think they are great all-around dogs. The can go go go, if you want them to, they can lay at your feet and relax. They can be trained to do anything including police and military work. They learn quickly and enjoy good training. You can have them with other critters, people, babies, old people. Just all-around great dogs.
