Diamond starts with a foundation of safe, consistent, nutritious, and tasty foods. They keep a tight focus on the important topics pet owners are most concerned with.
Diamond manufactures their food themselves, at their own state-of-the-art facility right here in the USA. They do their own on-site product testing to make sure everything meets their high standards of production.
Diamond bases their formulas on all of the most recent scientific research on pet nutrition. They use their own Proprietary Probiotic Technology (one for dogs as well as one for cats), superfoods like pumpkin, kale and blueberries, natural antioxidants, DHA for puppies and kittens, insoluble fiber for hairball control in cats, glucosamine and chondroitin for joint support, and no artificial ingredients of any kind.
They have a very strict practice of testing all of their ingredients before and after they have been incorporated into the products in order to ensure they are up to nutritional standards.
