Nourish your dog’s mind and help him think more like he did when he was younger with Purina Pro Plan BRIGHT MIND Adult 7+ Chicken & Rice Formula dry dog food. Around age 7, a dog’s brain begins to change how it metabolizes glucose, which can affect learning or awareness. Our proprietary research shows that enhanced botanical oils provide an efficient fuel source for the brain, in dogs age 7 and older, and these oils nourish your dog’s brain, helping him think more like he did when he was younger. Alertness and mental sharpness are promoted in dogs over the age of 7 who eat this food daily. This dry dog food has chicken as the number one ingredient, which provides your dog with a high-quality source of protein. Glucosamine and EPA, an omega-3 fatty acid, support your dog’s joint health and mobility, while vitamin A and linoleic acid promote healthy skin and a beautiful coat. You can feel good about feeding him a formula designed to deliver top-tier, highly specialized nutrition.
