I'm sorry if this site has been shared already--I've been to this website many times but just noticed this section. Maybe I missed it or maybe they just added it? I don't know but it was very cool to go through all the old photos & see that the variety in shape, size, head, muzzle length, etc in Chi's has not because of "bad breeding" (IMO anyway). It's simply the way it's always been at least as far back as these photos go. Kennel clubs just picked & chose the look they liked best & called it "correct"..or so it seems to me. haha
Anyway, I hope you enjoy as much as I did!

I also found it interesting there weren't many LC Chi's in the photos. I know the LC was created by crossing something with the Chi (Pom or Papillon?...I can't remember details so if someone knows please post!) Very cool stuff!
