Some dog food manufacturers make holistic dog food that contains natural ingredients. The significant difference between holistic dog food and most commercial dog foods is the quality of the ingredients.
Though animal byproducts are often the animal protein source in commercial dog food, animal byproducts are not usually included in holistic dog food. Animal byproducts are meat pieces that are not suitable for human consumption. Some holistic dog foods use only human-grade ingredients. Holistic dog food may have vitamins, minerals, and anti-oxidants added.
