Because your dog is unique and ORIJEN pet foods are packed with animal protein, feeding requirements will vary with breed, environment, age and activity. That's why we suggest using the feeding guide as a starting point, and monitoring your puppy or dog's weight and adjusting amounts as needed. We also recommend feeding your pet twice daily and always keeping fresh, clean water available. When switching diets, transitioning slowly will give your pet's digestive system time to adjust to the nutrient-levels in ORIJEN. Over a 10-14 day period, gradually mix in ORIJEN, increasing the amount each day so that by the end you are feeding 100% ORIJEN. See your veterinarian regularly. To help maintain freshness, we recommend sealing the bag tightly and storing it in a cool, dry location.
