On a related note, but nothing to do with ruffs......
I brought my dogs to a "real" Sheltie breeder for grooming two weeks ago.
I don't know what she did to the boy's hocks, but even after two weeks and wallowing in the mud of the cottage, those hocks are fluffed out and looking great.
I know she only uses scissors....if I can get the secret from her, I will share!
