Why Senior Dogs Need Specialized Nutrition
Dogs entering their senior years often experience changes in metabolism, muscle mass, joint flexibility, digestive efficiency, and cognitive function. Feeding a diet tailored to these age-related changes can help support a better quality of life and maintain healthy aging.
