I got harley when he was 4 months old. The breeder I got him from had given him a bath and he looked great. About 3 weeks later, his puppy hair seemed to be getting really badly matted. My groomer cut his hair real short to get rid of the fine "puppy hair" - he looked kind of funny - his legs looked really long. He's doing great now and his hair is really pretty. I don't really know the answer to your question but thought I would let you know what I did.
