Protein percentages are a matter of great debate: how much is the ideal amount and how much is actually in food. My personal non-expert choice for Yorkies is over 20%, but no more than 34-35%. There are Yorkies who thrive on more, but I don't think we have any comprehensive studies on what it does to them over a lifetime.
Keep your dog properly vetted, checking kidney and liver values annually, and choose a food in that range that agrees with your dog.
