Below are photographs showing puppies playing in the snow! Note the ice balls that have formed on the long coated bitch. And note that the pup who has a full coat with guard hairs, has NO snow stuck to her, and the other pup, who still has a baby coat with minimal guard hairs, has hardly any snow stuck on him and no ice balls at all!
These photographs show the difference between long coats and normal coats. The 35 cm of snow they were playing in was very dry and powdery - just like sugar when you pick it up. One can't even make a snowball with it as it runs through your fingers like sand and blows away. However, it seems to ball up quite nicely on the fluffy's coat.
