You're right, some dogs/yorkies are just so picky - and it's tough when that happens. Have you tried sprinkling Parmesan Cheese on the food yet? It can do wonders in making it more appealing/pungent/yummy smelling to a dog.
Otherwise, what about a rotation diet, where you keep a few different foods on hand and rotate every few days to keep his appetite stimulated....have you tried that?
Does his body weight feel okay to you?
