I have to make feeding time a game of sorts for my yorkies. I throw some on the ground and they chase after it and then once they start eating, they come up to the bowl and eat the rest. Yorkies, in general, are picky eaters. I would stick to the Canidae and try sprinkling some grated parmesean cheese (the kind that comes in the green can) on top and see if that helps. The grated parmesean cheese is small enough so she can't pick off the cheese and leave the food!
You could also consider pouring some low sodium chicken broth on top and see if that helps.
