I agree if you are not going to be happy with her than take her back now. But if you already love her (she is precious) then "what a purebred yorkie looks like" should not determine your love for her. I got a male yorkie [Tigger] and was told he would be 5-6 lbs, make that 15-16 pounds. Since I wanted a female and a smaller yorkie I adopted Nina, AKC purebred and NOW I am happy. Tigger is loved but I knew until I had what I wanted, I wouldn't be satisfied. Think about it and go with your heart. Good luck!!
