Please be careful about getting a Yorkie from a breeder you do not know. Especially if you are having it shipped because what do you do if something is wrong with your new baby. It will be better in the long run to spend more money buying your yorkie from a reputable breeder than on vet bills. I got Buster from a pet store which is the same gamble you get when you buy from an unknown breeder. I spent over $2,000.00 the first three months because he had a bad case of kennel cough which became pneumonia and 2 types of parasites. He also need to get LP surgery $3,000.00, bad knees, which reputable breeders try to breed out by not breeding dogs who have genetic issues. I would look at the Yorkshire Terriers Club of America breeders site
Yorkshire Terrier Club of America About The Club and see if you can find a good breeder in your area. Good luck with your search Yorkies are wonderful!
