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.


Beet pulp is an important source of fiber that is good for helping your dog maintain intestinal health and can enhance his ability to absorb ingredients. Beet pulp is the material that remains after sugar is extracted from sugar beets.
There are two types of fiber: Nonfermentable and fermentable. Nonfermentable fiber remains undigested as it passes through a dog's intestines, providing bulk to move wastes out. Cellulose is an example of a nonfermentable fiber.
In contrast, fermentable fiber is broken down in the intestines into short-chain fatty acids that provide energy for cells that line the intestine.
Moderately fermentable fiber does both: It provides bulk to move waste and supplies energy to cells lining the intestine. Beet pulp is a moderately fermentable fiber. IAMS™ products contain a patented, moderately fermentable fiber, beet pulp, to keep your dog's digestive system healthy.
Beet pulp contains no toxins and is not harmful. It is a very safe fiber source. Beet pulp does not affect coat color. There is nothing in beet pulp that can affect coat pigment—the inside is light in color, and the dark outside peel is not used in our foods.
By definition, beet pulp is the material left over after the sugar is removed from sugar beets. Therefore, beet pulp contains no sugar.
There is no evidence that beet pulp causes bloat. Bloat (gastric dilatation-volvulus or GDV) is related to a stomach defect that delays the stomach’s emptying. It is believed that bloat is not related to diet or ingredients, such as beet pulp. However, the cause of bloat remains unknown.
IAMS has conducted extensive research on many types of fiber. The results of this research point to the fact that beet pulp maintains intestinal health and works with other nutrients to provide optimal nutrition in all of our products, including IAMS™ ProActive Health™ Adult MiniChunks. No other food manufacturer can match our formulas. Only IAMS holds a patent for moderately fermentable beet pulp.
