The ideal coat will change from a puppy's black and tan with a cottony texture, to a steel blue and gold with a silky texture as an adult.
However, that doesn't always happen. Some will keep their puppy coat and remain black with a cottony texture. I have one right now that I'm certain will not transition the way it is supposed to. Some will also incorrectly transition to a wiry textured coat that does not grow very long, and the experts no doubt know of other variations that I haven't mentioned.
BTW, I'm impressed that you keep your pup's coat long. That is especially difficult with a cotton coat, since it tends to mat more easily. I just keep my cotton coated girl in a short cut. My silky textured boy is much lower maintenance, even when the coat is long.
