Don't think you can really tell coats until the puppy has lost it's puppy coat. I've seen fuzzy turn into very correct and very wavy but short also turn into a great adult coat.

I had a yellow puppy that we called "big red" - he had the red collar and the longest coat I had ever seen on a yellow puppy. He was my pick from day one so naturally I just knew he would end up being a long-coat. But nope he grew up and had the most beautiful coat. Won his class at the Potomac, as did his mother and went on to get his GCH.

I know why you are concerned - I was too. Remember he's just a baby and he'll do a lot of changing before he's mature.

Good Luck,
