You should feed your puppy enough of the proper food to meet its energy needs. Use the feeding guide on the label as a starting point. Measure the dry food with a measuring cup. Adjust the amount to maintain optimum body weight. Amounts may vary depending on age, size, activity level, temperament, environment and health. At every veterinary visit, discuss your puppy's body condition, diet and amount of food you're feeding to ensure your puppy's best health.
Just like people, every dog has unique nutritional needs based on age, health and activity level. It's important to choose your dog food according to your pet's age and lifestyle because of the biological changes your dog will go through.
