I was talking to someone today who said they cant find a good breeder of gsds and i wondered if it was because white is a kennel club fault, is it possible to find a good breeder whos not just in it for the money as the colour sells better.
I have messaged you the name of a breeder of white GSD's I looked into who were really helpful and had fully health-checked dogs. I hope it will be of help to your friend.
