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
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.
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.
| 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 |
Teeth are important players in the digestive process.
As teeth grind up food, debris accumulates on the tooth surface and attracts bacteria. This accumulation of debris and bacteria is called plaque. Plaque is easily removed from teeth by brushing—that is, when teeth are brushed frequently.
If the plaque isn't brushed away, mineral deposits cause it to harden on the teeth. This is called tartar. Dark yellow or brown accumulations on the teeth are indicators of tartar, which is difficult to remove.
If left untreated, plaque can lead to damage of the gums (gingivitis) or the jawbones and teeth (periodontitis).
Keeping a pet’s teeth and gums healthy involves regular brushing and professional cleaning. Unfortunately, many owners have problems brushing their dogs’ teeth on a regular basis.
Special diets also can help reduce tartar buildup between cleanings. Most dental diets are formulated with a tough kibble that is texturized to scrape off some plaque.
Our dental technology uses a patent-pending manufacturing process that enables dry-food kibbles to control tartar buildup. This process does not affect the nutrient content of the food or the size of the kibbles.
IAMS™ researchers have looked at the effects of feeding dogs dry diets with our dental technology. In each of these studies, two groups of animals were fed our formula, either with (control) or without our dental technology.
All animals had their teeth thoroughly cleaned.
After 28 days of eating one diet, animals’ teeth were examined for tartar.
All animals then received another thorough cleaning.
Then diets were switched for another feeding period.
In dogs, the diets featuring our dental technology reduced tartar accumulation as much as 50% compared to dogs fed the control diet.'
