There is no such thing as a "teacup" chi...that word is just a marketing tool to entice people into thinking they are buying a "special" or "rare" type of chi.
i have learned from people on this forum that "deerhead" and "appledome" are two different structures of a chi's head. "appledome" being accepted by the AKC, and "deerhead" not being accepted (at least i think thats what the AKC website says, i'm sorry if i'm wrong). my chi is a "deerhead." i think it's just a way to describe a certain feature about the chi.
