It seems that none of the puppies are fluffies! Even the little tri girl that I thought for sure was fluffy, turns out just long puppy coats.
I posted a new picture of Scooter one of the fluffy "suspects" and her coat is beginning to look more like the usual corgi puppy coat. So I ended up with 3 puppies with shorter coats and 3 puppies with longer coats and no fluffs. Always something interesting with corgi puppies.

The puppies are now 6 weeks old, three are normal coated, one fluffy and a couple are growing a little more hair than I expected! I always knew Dora the tri was fluffy, but Scooter and Bill are also looking fluffier than the others. I am posting a few pics of them, and welcome opinions :) It's been a long time since I had fluffy puppies and know some people are "fluff connoisseurs"
