It's important to note that even when feeding your dog species-appropriate meals, it may not be a good idea to feed the same amount of the same recipe, everyday. Wild carnivores eat what they can catch. If they can't catch they don't eat, which initiates a fast that helps maintain a healthy gut. To replicate this beneficial scenario I vary my dog's recipes, daily ration, feeding times and fast her at least one day a week. But her total weekly ration remains consistent based on her ideal weight and level of physical activity.
