As small-breed dogs get older, their nutrition needs change. Hill's Science Diet Small & Mini Adult 11 dry dog food is tailored nutrition to support healthy aging during small & mini dogs’ golden years. The small kibble is specially made with prebiotic fiber to help your little, older dog's digestion, while the omega-3 fatty acids from fish oil promote joint health. This senior dog food uses a balanced set of minerals to support a healthy heart, healthy kidneys, and a healthy bladder in toy breed dogs, while the omega-6s and vitamin E nourish the skin and coat. Since immune health is so vital for older dogs, this pet food made with natural ingredients uses a special blend of antioxidants to promote lifelong health.
