Yes, people are clueless. I see that here too occasionally. All Silkies should
be crested or have a topknot. (for those of us who can’t get unstuck from dog lingo lol) There are two varieties of Silkies, bearded and non-bearded, which is just as it sounds.
I believe it is technically called a crest in Polish as well. As far as I know, like Silkies, all Polish should also have crests.
