ok. i had to go look up the AKC definition of silkies.
from the picture they have on the site, i will have to say it DOES look like some of the yorkies on this site.
American Kennel Club - Silky Terrier
"
The general public occasionally confuses this breed with the Yorkie, but in reality, the Silky is larger and more closely related to the Australian Terrier. "
this sentence is found in the very fist paragraph on the page. so it is not that uncommon for people to get confused.
