Diamond Maintenance Adult Dog Formula is designed for moderately active adult dogs and, because maintenance diets are fed during most of a dog's life, is formulated as a complete and balanced diet with added benefits which promote good health and long life.
For more than 30 years, Diamond Pet Foods has stood for "super premium" pet food at an affordable price.
For more than 30 years breeders, veterinarians, hunters, and pet owners have relied on the Diamond name for consistency, super premium quality, and value.
The Diamond Difference.
Guaranteed Levels of Omega-6/Omega-3 Fatty Acids
While all pet foods contain omega-6 (linoleic acid) Diamond, is one of the few which supplements with omega-3 (linolenic acid) to ensure the proper omega-6/omega-3 balance, according to scientific research.
This balance (5:1 to 10:1) promotes:
- the reduction of inflammation in skin, joints, and gastrointestinal system
- improved overall health
- an enhanced immune system
High Quality Ingredients
Diamond Maintenance Formula for Dogs begins with premium ingredients, including:
- Multiple animal protein sources for the proper balance of amino acids. Includes chicken and egg protein.
- Flaxseed: A natural highly palatable source of omega-3 fatty acids.
- Chicken fat: One of the most digestible of pet food fat sources, it also yields optimum levels of linoleic (omega-6) fatty acids. The ideal fat source for a show-quality coat.
- Naturally preserved with mixed tocopherols (a form of vitamin E).
- Chicken by-product meal: Low ash, highly digestible, primarily smooth muscle protein.
- Correct and controlled levels of vitamins and minerals: Specifically formulated levels of vitamins and minerals to guard against deficiencies (resulting from inadequate amounts), and toxic reactions (resulting from excessive amounts) both of which may be harmful.
Consistency Through In-Plant Control and Manufacturing
Because dogs are sensitive to diet changes, Diamond utilizes a fixed formula and single source suppliers to ensure Diamond Maintenance Formula for Dogs maintains the same taste, texture, and nutritional content in every bag. Diamond Pet Foods manufactures their own pet foods and controls all critical aspects of its formulas.
State-of-the Art Production Facility
Premium ingredients are only the beginning. How pet foods are produced is just as important as what goes into them. Unlike some pet food companies, Diamond uses a unique in-house processing system which:
- retains the maximum potential of each ingredient
- enhances nutrient digestibility
- produces exceptional flavor and uniform texture
- maintains overall product consistency
