I can see why people are confused. Large Yorkies do look a lot like Silkies and small Silkies remind me of Yorkies. Remember Silkies are a Yorkie mix.
I ran in to a guy with a large Yorkie and a small Silky while on a walk the other day. I thought they were both Yorkies. The only difference was the Silkies head was large, with longer snout. But then I see Yorkies on here all the time that look like him. oh well.
