It's important to know 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 two to three days a week. But her total weekly ration is  11-12 lbs of food to maintain her ideal weight based on her activity.
