Dog food is considered “complete and balanced” when it meets AAFCO nutritional standards for essential nutrients like protein, fat, carbohydrates, vitamins, and minerals. Protein supports muscle and immune health, typically making up about 18–30% of adult diets depending on activity level. Fats provide energy and help maintain healthy skin and coat, usually around 5–20%. Carbohydrates offer digestible energy and fiber from ingredients like sweet potato, peas, or grains. Every formula we feature is selected to meet these nutritional requirements for your dog’s life stage.
