Royal Canin is expensive corn cereal for dogs. I would at least look into meat based brands like nature’s variety instinct, and merrick back country. Or even a refrigerated food like fresh pet. Despite what anon says I know for a fact what nutrition is taught at the vet school in my state. And it is an option elective class that covers most small animal pets. And the text books are written by vets in association with the big 3 which use biased budget based “science”. Dogs are mesocarnivores regardless of size or breed and a corn based diet is not ideal.
