Feeding your dog Purina ONE True Instinct Premium Dry Dog Food is easy. Just measure out the right amount based on your dog's age, weight, and activity level. You can find the feeding guidelines on the product package. Make sure your dog always has access to fresh water. Store the food in a cool, dry place and keep the bag tightly sealed to maintain freshness. If you're switching your dog's food, do it gradually over a week or so to avoid digestive upset. If your dog has any special dietary needs or health concerns, it's a good idea to consult your veterinarian.
