Key Features

• High quality protein: Provides the amino acids needed to support and maintain lean muscle mass in adult dogs.

• Omega-6s and vitamin E: Support skin health and a shiny coat, which is especially useful for dogs with seasonal coat changes.

Who It's For

Hill's Science Diet Adult 1-6 is best for owners of adult dogs aged roughly 1 to 6 years who want a reliable, vet-recommended maintenance food that focuses on digestion, muscle maintenance and skin and coat condition. It is a good fit for pet parents who prefer formulas made with natural fibers and a clear nutrient focus rather than novelty ingredients.

Dogs with specific medical conditions or highly sensitive stomachs may need a prescription or specialized diet; likewise, owners seeking grain-free or raw-style diets should look elsewhere. Also, if a dog is an extremely picky eater, trial-size feeding is recommended because some pets vary in their acceptance of the kibble size and shape.
