Well, some people say that's not a good food, but I am beginning to be of the opinion that if they are eating a kibble and like it that we should leave well enough alone. It seems that people sometimes, not always, run into trouble by switching their food and sometimes, not always (again) create a picky eater. Lots of people have been raving lately about Chicken Soup for the Dog Lover's Soul, though, and it's a good food. Also, Innova EVO. I'll let others give you some opinions, because all yorkies are different.
