Please listen to all the good advice. Your little guy could be in serious danger. Three days is a long time for yorkies. How old is he? How much does he weigh?
Please, please get him some help asap. If it were me I'd take him to the er vet. Something isn't right...follow your instincts and get him help.
Please update us when you can.
