Your puppy’s nutritional needs will change as he grows into adulthood, but how do you know when your puppy is ready for adult food?
Depending on his breed size, at some point between 12 and 24 months of age, you should reexamine your puppy's nutritional needs and choose the right adult formula. His adult food could depend upon his metabolism (Does he gain weight easily?) and his activity level (Is it low, normal, or high?) These factors can help you find the ideal food for your dog.
The transition to a premium adult formula should begin when your dog approaches adult height and weight. The kind of dog you have will determine the right time to switch. When you do switch to adult formula, follow the same four-day process as you did when introducing your puppy to premium puppy food.
Small-breed dogs tend to mature physically much sooner than large-breed dogs. Follow these guidelines to help you decide when to switch formulas:
As your new puppy quickly matures into adulthood, he needs nutrition appropriate for his 'new' body. That means a high-quality, premium adult formula. Most veterinarians agree that feeding a complete and balanced premium food, such as IAMS™ ProActive Health™ Adult MiniChunks, throughout your dog's adulthood can promote a long and healthy life.
Chicken, a complete protein source, is a key ingredient in IAMS™ dog foods, including IAMS™ ProActive Health™ Adult MiniChunks. As an animal-based protein, chicken can help maintain your dog’s muscle structure and naturally provides all the amino acids essential to carnivorous animals such as dogs. Plus, chicken adds great flavor.

Common chicken ingredients in dog food include chicken, chicken meal, chicken byproduct meal and chicken fat:
Another common chicken-based ingredient is natural chicken flavor, also called chicken digest. Natural chicken flavor adds palatability and nutrients. It is high-quality protein and fat material that has been reduced to amino and fatty acids to improve flavor through an enzymatic process.
Internal organs are rich sources of protein, fats and minerals, such as iron, that are essential to dog health and add to the palatability of the pet food. Including some ground bone provides a good source of minerals, such as calcium. Some pet-food manufacturers formulate their products without such ingredients to appeal to dog owners, rather than to help dogs achieve optimal health. However, the nutritional needs of dogs are not the same as the nutritional needs of humans.
Dried chicken-protein sources in our chicken-based dog foods undergo an extra refining process. Refined chicken meal and chicken byproduct meal are excellent and complete sources of protein because they naturally contain each of the amino acids that are essential to dogs.
