Feeding guidelines: The recommended daily feeding amount is based on the average nutritional needs of the adult dogs. In order to maintain the ideal posture of the dog, the metabolic status, body size, activity level, age and reproductive capacity of the dog will affect the amount of PURINA® PRO PLAN® dry dog food required for the dog. The PURINA® Pet Specialist provides you with basic feeding guidelines for recommended daily feeding. When the dog's weight is found to be too light or too heavy, adjust the serving size. To help the dog maintain its ideal posture, check the weight of the dog regularly and make sure that the ribs and waist are clearly visible from the dog. Keeping the dog's ideal body state has a long-term impact on the dog's life
