The word TEACUP is not recognized in the AKC standard for yorkies, it is just a word to refference to the tiny Yorkies. Personally i love the tiny ones they are calmer than the standard yorkies. Our Yorkies and parti yorkies are loved very much, and only go to good responsible Yorkie owners. Our spoiled little Yorkies come from good healthy Yorkie lines, with tiny genetics, in other words the parents and grand parents where tiny little Yorkies, so they will be tiny and have good sturdy healthy little bodies. I assure you that our little baby doll Yorkies are happy confident and healthy Yorkie babies! No inbreeding to achieve smaller.
