Again, where do you get the "unhappy" or "in pain" from the images ? I am curious. I guess I don't have the trained eyes that you folks possess.
Thanks again though.
He is only 5 months old and the ear stood before he started teething? There is a good chance the ear will come back up. Both the FCI and SV standards mention small inconspicuous white marking on the chest is permitted but not desirable. It is not uncommon for the white on chest and toes to fade out and almost disappear as puppies mature.
As far as his back, I would get a second opinion. The fact that your vet has treated GSDs for 30 years and went to Cornell does not make him infallible, unfortunately he is human and therefore can make mistakes or errors in judgment.
What I see here are poor photos, in every photo he is just standing not even 4 square, his hind feet are under his loin. Go out there with him and get some moving shots and show him just being a puppy having fun and you will see a puppy with a much better top line and a happier look on his face . or take some photos of him stacked and then we can gain a better opinion.
PS My dogs also get that sad sack look on their faces when they see me coming with the camera.
All I can tell you is that isn't what I am looking for in a German Shepherd Dog,
he seems a bit crippled to me,
I am breeding dogs that can scale a 7 foot fence within seconds and still smile.
I am going to try and get a Schutzhund title on one of my dogs, but as it stands, right now
I am getting great feedback from people who have got dogs from me and some are very experienced
in training the GSD and some are beginners, but they have no question that their dog is the best,
my dogs I breed don't really have that much angulation.
In my personal opinion, I would not pair up his parents again and breed them.
I do repeat breedings, same 2 dogs over again if I like the results, I hate surprises.
I hate to say it, but the only time I have seen a dog stand like that is after he had been hit by an automobile
What you have is a happy healthy pup that doesn't know he is over angulated,
don't treat him any different, exercise him like a regular dog, and he'll be happy
