White ones are normally deaf , it a comon problem in WHITES look out for the hocks , the lower rear part of the legs , as many gsd have hock problems, all to do with the show ppl and the breed standered says something about sloping rear that twaddle , get one from a working breed line , what is level and square at the back also look for hip displasia score . And elbows < hock A show dog will look nothing like a gsd from a working background but more than likly be quiet a bit larger than a typial show gsd gsd DO suffer from ear problems but that no biggie normally just a build up in wax a sable is a rare colour and quiet sought after if you like the white or cream ones, better maybe you be better going for a belgian shepherd ,or dutch shepherd a lilbit smaller , but look the same have a look at the malinois http://www.akc.org/breeds/belgian_malino... I just looked on the akc , site and saw no dutch shepherds but actually saw they come under dutch sheep dogs , knows in europe as Groenendael's all black shepherds.
No white or "cream" German shepherd is going to have good bloodlines. Period. There are some Yahoo groups that specialize in GSDs.
They can answer a lot of your questions. There are way to many things for you to learn about GSD that you can get from one question here.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
