Grains would not be a part of an ancestral canine diet. Canines were shaped by evolution to consume an animal-based diet with very low amounts of plant-based foods.
Feeding dogs kibble was largely a post-WWII phenomenon.
Carbs in a diet drastically reduce a dog’s stamina and aerobic capacity, do a number on teeth, encourage obesity, dry the coat, and contribute to general ill health and lethargy.
Have you ever seen a dog raised on a balanced PMR diet? There is no comparison in the condition. The only thing that’s ridiculous is believing one can feed a dog processed cereals and rendered meat “products” and think one won’t have serious health issues down the line.
