Great answer Julie!
Would you beleive four times in one day (yesterday at the dog show) people came up to me and asked if my show dog was a teacup? These so-called breeders and pet shops seem to have a stronghold on public perspection. I think there's more people out there who have some idea what a "teacup" is than who actually understand the standard.
donnathedoula - I apologize for the inside jokes. We don't in any way mean to offend. It's just that there's a lot of people out there advertising "teacups" as a sales gimmik. Please do not ask for or buy from anyone who will sell you a "teacup." If you do a search through yorkietalk you'll find a ton of info on why the term "teacup yorkie" is a fallacy and the health and social impacts of buying such dogs.
Here's also a link to my own website where I've posted some additional info:
