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.
Fat contributes more than twice as many calories in a diet as proteins or carbohydrates
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.

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.
Learn more about chicken’s role in your dog’s complete, well-balanced diet.
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.
