Hi Michelle
Tino is absolutely adorable!! Breeders that use the term teacup are usually just in it for the money. Any breeder who knows the yorkie standard would not call their yorkies teacups...There is no such thing as a teacup yorkie...AKC only recognizes one type of yorkie and that is a toy yorkie. Yes, some are smaller and some are larger but they are all classified as toy yorkies. I know yorkies who are only 2 lbs adult weight and some that are 25 lbs at adult weight. You can go to
www.ytca.org and read what they have to say about teacups.
Your Tino is beautiful!!
