I had always assumed this was pretty standard for black German shepherds to have patches. My dogs father for instance, was fully black besides his butt. Haha. Now my dog has a white butt, blonde leg highlights, a white chest and some random patches.
But potentially if the spots are just showing up more and more, potentially take a look at this, uveodermatological syndrome or as someone else suggested, vitiligo.
