What is the best food to feed my Pomeranian?

Yep. I buy him pedigree food, but I do not know if it is any good. I tried researching online on what is the best food for him, but it is ridiculous, I cannot find a thing. What brand is best for him? What type of food is best for him? It doesn't even have to be a dog brand. For instance, maybe I could just feed him chicken with no salt on it, I don't know. I need direct answers, not the vague ones that I find online. Thanks.

He is an eight-year-old, male Pomeranian. He is not overweight. He seems to be quite healthy. I always give him exercise. He will eat whatever I give him. His teeth are healthy. He has no health problems or diseases.
