Unlike larger-breed dogs that are considered mature or senior at age 5, small-breed dogs usually don’t experience age-related changes as early. But by age 7, your small dog is mature or senior, and his nutritional requirements are changing. You can help keep your dog active, happy and healthy with a specially formulated mature diet that delivers highly digestible, enhanced nutrition.
The changes your small dog is going through affect him in many ways. You may notice a dull, dry coat and flaky skin, energy loss or weight gain, more frequent intestinal problems, joint stiffness and a loss of lean muscle mass. It’s true that an aging dog may require fewer calories, but your mature or senior dog still needs high-quality protein and carefully balanced nutrients.
What your dog needs is a high-quality, balanced maintenance food formulated for a small dog’s changing metabolism. Look for options with these age-essential nutrients:
These ingredients are the keys to mature nutrition whether you feed dry or wet dog food or give your dog treats.
Additionally, small dogs have small mouths and small stomachs. A nutrient-dense mature formula with smaller kibble may help make food easier for your dog to chew.
Older, less-active dogs are prone to weight gain. Keeping your dog at a healthy weight can help minimize the risk of developing diabetes or joint stress. Your dog can benefit from a weight-control diet with these key ingredients:
While your mature or senior dog’s nutritional needs may be changing, that doesn’t mean he doesn’t have many active, happy years ahead. Make sure your dog can make the most of them by feeding him a proper diet designed for mature small-breed dogs.


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.
