Yorkshire Terrier Stud Dog

Please i want my dog to have puppies so bad. She is a Yorshire Terrier and Chihuahua mix, but i want her babbies to look and act like yorkies. See her mother is a pur breed yorkie and i want her babies to be mostly yorkie. So please help me. She is a 1yrs old and weighs 8lbs. Her name is Cupcake and o love her to death, she's my baby and she has all of her shots. Thank You!!
