Buying Guide: Senior Dog Diet Considerations
Key factors when selecting a diet for senior dogs include digestibility, energy needs, and the balance of minerals that support heart and kidney health. Smaller kibble can ease chewing and dental sensitivity, while larger kibble may suit dogs with robust chewing power. Texture variety—kibble and wet options—helps accommodate preferences and hydration needs. Joint support ingredients like glucosamine and chondroitin, along with omega fatty acids, are common in senior formulas and can contribute to mobility and coat health. It’s important to monitor weight and adjust portions as activity changes with age. Consider your dog’s breed, size, dental status, and any vet-recommended nutrient targets when choosing among these Hill’s Science Diet Senior options.
