Can you post a picture of him anywhere? A few of our members have a lot of experience with yorkies. Be aware that it does take time, even a year or more, for a puppy to grow the long flowing coat that most people are familiar with when they think of yorkshire terriers. It's possible that your dog just isn't old enough to exhibit the coat that you are expecting. Who is he registered with?
I have a Yorkie who is a year and a half old. At 16 weeks, your puppy will still have his poofy puppy hair. I love it when it's like that. It won't get long and straight for quite a while. I can't remember exactly when he lost his puppy hair. It probablly wasn't until he got about 7 months old or so. Eventually it will start coming out and will turn smooth and grow long.
Yorkies coat grows like humans hair. They are born with short hair and it grows as they age. They won't have a full adult coat until they are about 2 years old.
Some yorkies grow faster and some slower depending on the texture but I would expect a 4 month old to have shorter, sorta scraggly looking hair. They will be very fuzzy as pups if they have a softer, cottony type coat.
Here are some pictures of Jasmine. She turned 3 months old on the 11th, so is not quite 16 weeks, but that is what the hair should look like. You can also see a picture of Cricket on that page. It takes a while for the hair to grow that long.
