Senior dog nutrition requires adjustment for metabolic changes, reduced activity levels, and age-related disease management to support optimal welfare across the final life stage.
Senior dog nutrition is a welfare domain where common misconceptions cause harm — particularly the widespread belief that all senior dogs need reduced protein diets. The evidence shows that healthy senior dogs need adequate protein to maintain muscle mass, and muscle loss (sarcopenia) is one of the most significant welfare-compromising processes in aging dogs. The caloric reduction that many seniors need from reduced activity levels does not justify protein reduction that accelerates the muscle wasting already associated with aging. Veterinary-guided individual nutrition assessment rather than categorical senior diet selection provides the most welfare-protective approach, particularly for dogs with concurrent health conditions requiring dietary management.
