to the poster , Even tho we know a teacup is a dish piece we also know that a lot of people use this term for a very small/tiny yorkie and I know it , and most of the members here also know it , but there is so much controversy with this word just do a search here, that's why you are getting the "there is no such thing" anyways I just want it to point to this , I didn't know if you were getting confused here , perhaps you are new to all the teacup dilema ......I know at one point I was.
I know you mention the yorkie was given to you so I don't think there was a $$ involved when they said "teacup" .
