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.
If you’ve got a big love for big dogs, IAMS™ has a large-breed puppy formula specially made for their nutritional needs.
Many large-breed puppies have a tendency to grow very quickly. Unfortunately, if this tendency is encouraged by overfeeding, developmental bone problems can occur. To avoid these problems, careful feeding management is necessary. This should include
Our specially formulated large-breed puppy formulas make feeding management easier because they are designed for fast-growing, large-breed puppies (those with an expected adult weight of more than 50 pounds).
A protein level approximating 26% in these formulas promotes healthy body condition and balances the protein with the reduced number of calories in the food. Research has shown that
The protein in our large-breed puppy formulas supports normal skeletal and muscular growth.
Fat contributes more than twice as many calories in a diet as proteins or carbohydrates do. As the fat level increases, the energy content of the diet also increases, making feeding management more difficult for large-breed puppies. Several studies have shown increases in developmental bone problems when a diet was overfed.2, 3
By reducing the fat content of large-breed puppy formulas to about 14%, the metabolizable energy (ME) of the diets can be kept to a low level of about 1,800 kilocalories per pound.

Our large-breed puppy formulas, such as IAMS ProActive Health™ Smart Puppy Large Breed, are made specifically for growing puppies with expected adult weights of 50 pounds or more. These puppy foods are unique because they are formulated with:
Reduced calcium and phosphorus levels with a normal calcium-to-phosphorus ratio to promote proper bone development in rapidly growing large breed puppies.
