As dogs age, changes occur in the way their bodies function, so it makes sense that what they eat also might need to change. The following list of health issues might be more common in aging pets.
- Decreased immune-system function
- More frequent intestinal problems
- Decreased mobility
- Dental issues
Special Nutrition for Special Needs
Decreased Immune System Function
Throughout a dog’s life, a process called peroxidation occurs. Peroxidation is a normal process that the body uses to destroy cells that outlive their usefulness and to kill germs, parasites, etc. This process, however, also can destroy or damage healthy cells. As your dog ages, the damage caused by peroxidation accumulates, which, in turn, increases the risk of certain problems, such as infections.
Antioxidants are naturally occurring nutrients that help maintain overall health by neutralizing the peroxidation process of cellular molecules. Some antioxidants, such as vitamin E, beta-carotene, and lutein, are naturally occurring nutrients.
Recent research sponsored by The IAMS™ Company found that dogs fed a diet rich in antioxidants such as vitamin E, lutein, or beta-carotene had improved immune responses and vaccine recognition. This might be especially important in senior dog care; IAMS research has found that as dogs age, immune responses can decrease.
More Frequent Intestinal Problems
Older dogs might have higher numbers of unfavorable bacteria and lower numbers of beneficial bacteria in their intestines, which can result in clinical signs of gastrointestinal problems (e.g., diarrhea).
Feeding a diet containing fructooligosaccharides (FOS), a unique fiber source that helps nutritionally maintain healthy intestinal bacterial populations, promotes growth of beneficial bacteria. Beet pulp, a moderably fermentable fiber source, also helps maintain intestinal health by providing energy for the cells lining the intestine and promoting small, firm stools.
Signs That Your Dog Needs Senior Food
Different dogs show signs of aging at different times, and much of this variation is associated with size. Larger dogs generally appear "old" sooner than smaller dogs. The table below lists the age at which various groups of dogs should be transitioned to senior foods, such as IAMS™ ProActive Health™ Senior Plus.
Dog Weight and Transition to Senior Food
|Weight Range||Age to Begin Transition|
|More than 90 lbs||5 years|
|51 to 90 lbs||6 years|
|21 to 50 lbs||7 years|
|Up to 20 lbs||7 years|

Beet pulp is the material that remains after sugar is extracted from sugar beets—not red beets. Beet pulp is a source of fiber in dog diets.
Fiber and Beet Pulp
Fiber can be classified as nonfermentable and fermentable. Nonfermentable fiber remains undigested as it passes through the intestines, thereby providing bulk to move wastes out. Cellulose is a nonfermentable fiber.
Fermentable fiber is broken down in the intestines into short-chain fatty acids that provide energy for cells lining the intestine.
Moderately fermentable fiber does both: It provides bulk to move waste and provides energy for cells lining the intestine. Beet pulp is a moderately fermentable fiber.
Myths About Beet Pulp
"Beet pulp is harmful."
Beet pulp contains no toxins and is a very safe fiber source.
"Beet pulp affects coat color."
There is nothing in beet pulp that can affect coat pigment. The inside is light in color. The outside peel, which is dark, is not used.
"Beet pulp contains sugar."
By definition, beet pulp is the material that remains after the sugar is removed from sugar beets. Therefore, beet pulp contains no sugar.
"Beet pulp causes bloat."
Bloat (gastric dilatation-volvulus or GDV) is related to a stomach defect that delays emptying. It is believed that bloat is not related to diet or ingredients, such as beet pulp. However, the cause of bloat remains unknown.
