He's a very pale sable(which is a colour pattern BTW not a colour) The black will spread & he might even get darker in colour It's not that usual in GSDs just that sables are usually dark red/tan but there are people breeding non standard colours like white sables & cream sables
This is a
German "gray"GSD(gray is the german name for the dark sable dogs)who gives you the idea of the correct sable pattern, your puppy will not be as dark but will have a similar pattern when he has finish casting his puppy coat
Apart from all black, gray sable is my favour colour
LOL when they shed they lose coat like it going out of fashion ;)
