How about leaving these young bodies alone as much as possible? No neuter, spay or over vaccinations until they are fully grown?
It is easy to say to not care but it is a bummer when they don't get up. I know it doesn't change the dog's personality but a great part of the beauty of a GSD are the ears. They make the dog look regal. Ever seen the Farside cartoon about domestication of the wolf?
I am always sorry for owners of a GSD if the ears don't get up.
I have a sight hound with erect ears , so the opposite problem. He is 11 years old now and I still notice it but wouldn't trade him for the world.
