Not sure about kibble but I know raw or freeze dried Primal is all life stages. Their website lets you put in quick info and calculates approx. how many nuggets to feed for puppy of a certain age. https://primalpetfoods.com/pages/feeding-calculator
PUPPIES
In the wild, when puppies reach 4-5 weeks of age, the mother dog will naturally begin to regurgitate some of her raw foods for her puppies to consume. Thus, when domestically reared puppies reach approximately 4-5 weeks of age, you can begin introducing them to Primal Canine Formulas. Puppies should be fed one to two small (1-2 teaspoons) raw-food meals daily in conjunction with either the milk they consume from nursing and/or other foods you may be supplementing. Puppies should always be fed from separate bowls, as competitive feeding can promote overeating and indigestion. Gradually increase the quantity of Primal Canine Formulas foods every 2-3 days until 8 weeks of age, when the puppies are consuming two tablespoons of Primal Canine Formulas twice daily. At this point (8 weeks), the puppies should be fully weaned and can be fed a diet solely of Primal Canine Formulas and raw meaty bones. Puppies 8 weeks of age and older should be fed approximately 4-8% of their body weight daily in Primal Canine Formulas. Factors such as breed, overall health and level of activity play a part in the necessary feeding quantities of all puppies. Please be sure to monitor your puppy’s dietary needs and adjust the feeding quantities accordingly.
