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 who eat a higher-protein diet better maintain muscle protein stores. By providing optimal protein levels from muscle maintenance, we can allow senior dogs to continue being physically active.
This research is contrary to conventional opinion that senior dog foods should contain lower protein levels than adult maintenance formulas in order to avoid progressive decrease in kidney function. However, senior dogs that were fed a high-protein diet had stable renal function and a lower death rate than those dogs fed a lower-protein diet.*
