What do I do if my dog won’t eat his food?

My dog has no interest in his food. I will offer it to him and he will sniff it and then walk away. Some days he won’t eat all day. Do we keep buying different brands to find something he likes or go back to a lower quality food that he used to like? I prefer to feed him nutritious, holistic/natural food with no fillers/by-products
