I don't know if it would work for a GSD, but you might try looking into what is called 'Force Fetching' for bird dogs. 'Hold' is first stage of force fetching & relativly easy to teach.
I've been through the process with a Labrador Retriever, and had excellent results. They are supposed to hold a rubber dummy during hold, but I had much better luck with a soft paint roller.
Might be worth looking into if you don't have any luck with anything else?
