I don't know, he looks just like Sir Theodore to me--and I was given the impression that Theo was, more or less, pure yorkie. Mine's five months, is six pounds, has the same coloring, square jaw, flop ears, and calm temperament. Hmmm, maybe Theo's a mix too...
Either way, lucky us.
P.S.--man, these ladies are after you... hang in there, I'm sure the bark is worse than the bite
