Im glad you are happy with your party yorkies .. but if you read the standard that is actually a genitic defect .. the standard of yorkies AKC are Blue and tan or black and tan.. the choc. golden and party are all genitic defects.. Just another way to get extra money ... Im sorry but this just buggs me . that people with the way things are in this world that people are still pulling these stunts.. sorry guys .. the money that you use to buy these choc. parti. etc.. are just a waste of money.....
