I try to politely tell them that there is no such thing as a teacup anything...and then give them my business card to refer them to my informative yorkie website.
If I think they want to chat a bit, I might go a little farther.
I try to educate people politely and always keeping in mind that they asked me a question, so they muct want an answer.
When people ask how much I paid for my dogs I tell them "a million dollars, at least that is her replacement value" lol
It usually gets a smile out of them...it keeps it friendly and light...
