In the past, veterinarians recommended diets for senior dogs largely based on the nutritional management of diseases common to the aging process. Research, however, has shown that special nutrition can help manage body-condition problems in aging dogs, such as obesity and loss of muscle mass. Senior dogs also benefit from special nutrition to help maintain bone and joint health.

Senior dogs tend to gain weight, despite consuming fewer calories, due to changes in their metabolic rate. Therefore, they can benefit from eating a diet with reduced fat levels and lower caloric density than adult maintenance foods.
Recent IAMS™ research in dogs also indicates that L-carnitine — a vitamin-like compound made in the body from the amino acids found in red meats, fish, chicken and milk — can help reduce weight in overweight dogs by escorting fat into cellular mitochondria where it is turned into energy.
Protein is the building block of muscle tissues. It is important for maintenance of muscle tissues, muscle strength and mobility. Recent research conducted by The IAMS Company has shown that senior dogs that eat a higher-protein diet better maintain muscle protein stores. By providing optimal protein levels from muscle maintenance, we can help senior dogs continue being physically active.
This research is contrary to conventional opinion that senior dog foods should contain lower protein levels than adult maintenance formulas to avoid progressive decrease in kidney function. However, senior dogs fed a high-protein diet had stable renal function and a lower death rate than dogs fed a lower-protein diet.*
During the aging process, cartilage between joints often begins deteriorating. Nutritional management can help maintain healthy bones and joints and mobility in dogs in several ways:
Some pet-food manufacturers have endorsed reduced levels of calcium and phosphorus based on the belief that excesses of these minerals are harmful to the kidneys. However, research has shown that no damaging accumulation of calcium or phosphorus was found in the kidneys of older dogs fed diets containing maintenance levels of calcium and phosphorus for four 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.'
