Large Yorkies are not that unusual, both of mine are about 15 lbs. There is no such thing as "teacup" its just a fancy way of saying small. The standard is 7lbs, then there are the teenies that are less. Way back in the day yorkies were around the 15 lb mark, then they were bred to be smaller. So kind of a sarcastic counter to people saying "teacup" we call the big ones "teapots".
