Can someone please post pictures and show me the difference between vaulted heads and non vaulted in Silkies? Which is preferred and why? Also what does the "beard" factor matter in silkies? Does a beard or non beard determine the difference between a show quality and not show quality? Can you show me pictures of a show quality Silkie and a pic of non show quality and tell me why and the difference? I NEED to be INFORMED!!! Don't understand the differences and why one is worse than the other!!! HELP!!!
