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, initiating a fast, which helps maintain a healthy gut. To replicate this beneficial scenario I vary my dog's recipes, daily ration and feeding times. I fast her at least one day a week. But her weekly ration remains consistent with her ideal weight and physical activity.
