Have you contacted GSD rescues in your region to see if they will do a courtesy posting of him on their website? That would be my first move if I needed to rehome one of my dogs.
Funny you should say that, I just emailed GSD and mentioned that I would get him altered if this improves his chance on getting a good home and what you said does make sense. I am looking into that!! Thank you
