Ok .. since the purchase of my "yorkie" three years ago ive question the possibility of her being mixed, becasue to start she weights 15 pounds. She solid thoug, no fat belly, very good muscle tone and runs like a speeding bullet. She has the exact color pattern , muzzle and head shape , ears every thing to what a yorkie should be. Ive never kept her hair long though, i had to shave her twice because of a skin allergies. so her hair of course came in a little course. just wanted to know if there are any other parents to plus size yorkies
