Grain free and gluten free foods are fine. Owner preference.
Low carb foods may or may not be fine. The less carbs, the more protein and/or fat. IMO high fat is not a good idea for Yorkies. High protein, well, to each their own. I think the general consensus among veterinary nutritionists right now is that high protein does not cause liver or kidney problems; however, if there is a problem present, high protein is not what should be fed.So again IMO, if a high protein food is fed, that makes it even more important to do bloodwork often to make sure the food doesn't need to be changed.
They do not need high protein. Whether or not they do better on it is really just an opinion right now. I haven't seen any studies to indicate that they live longer, healthier lives. It's an expensive energy source and the experts in canine nutrition say such a large amount is not needed.
Dogs should eat the food that they are healthiest on. My dog has eaten tuna as her protein source for months. I hate the idea, but it is what we can manage her best with, so that's what she gets.
