What it is Diamond Naturals Adult Dry Dog Food Lamb Meal and Rice Formula is a grain-inclusive kibble designed for adult dogs of all breeds. It uses lamb meal as the main protein source, paired with whole grains like brown rice and oatmeal. The formula includes probiotics for digestive support and a blend of antioxidants, vitamins, and minerals to promote overall health. It is manufactured by Diamond Pet Foods, a family-owned company with a long history in the pet food industry. ## Key features to know – Primary protein: Lamb meal provides concentrated protein, which is beneficial for muscle maintenance and energy. This formula avoids common poultry proteins, making it an option for dogs with sensitivities to chicken or turkey.

  • Grain-inclusive recipe: Contains whole grains such as brown rice, oatmeal, and cracked pearled barley. These provide fiber, B vitamins, and steady energy. If your dog does well with grains, this is a plus; if not, you may want a grain-free alternative.
  • Probiotics: Includes dried fermentation products to support healthy gut bacteria, aiding digestion and nutrient absorption. This can be helpful for dogs with sensitive stomachs.
  • Omega-6 and omega-3 fatty acids: From sources like flaxseed and fish meal, these support skin and coat health. Dogs with dry or itchy skin may benefit.
  • Antioxidant-rich fruits and vegetables: Blueberries, oranges, kale, and carrots provide natural sources of vitamins C and E, which support immune function.
  • No artificial preservatives, colors, or flavors: The formula is naturally preserved with mixed tocopherols (vitamin E).
  • Made in the USA: Diamond’s own facilities produce this food, with ingredients sourced from trusted suppliers. However, be aware that Diamond has had past recalls (e.g., 2012 salmonella contamination). The company states they have since implemented enhanced safety protocols. ## Who it is best for This food is ideal for adult dogs with moderate activity levels who do well on grain-inclusive diets. It is a good choice for dogs that need a lamb-based protein source due to poultry allergies or sensitivities. The balanced nutrition supports everyday health, making it suitable for dogs without specific medical conditions. Owners who prefer a budget-friendly, widely available brand with solid ingredients may find this aligns with their needs. ## Things to consider before buying – Grain content: This is not a grain-free diet. If your dog has a grain allergy or intolerance, look for a different option. Some owners prefer grain-free for various reasons, but note that the FDA has investigated a potential link between grain-free diets and dilated cardiomyopathy (DCM) in dogs. Consult your vet.
  • Recall history: Diamond Pet Foods had a voluntary recall in 2012 due to potential salmonella contamination. Since then, the company has updated safety measures, but some owners prefer brands with zero recalls.
  • Lamb meal vs. fresh lamb: Lamb meal is rendered and concentrated, but some dogs may do better with fresh meat as the first ingredient. This formula lists lamb meal as the primary protein, not whole lamb.
  • Calorie density: With around 355-365 kcal per cup (varies by batch), this is moderately calorie-dense. For less active dogs, adjust portions to prevent weight gain.
  • Transition period: When switching to any new food, do it gradually over 7-10 days to avoid digestive upset. Even with added probiotics, sudden changes can cause loose stools.
  • Consult your veterinarian: Always discuss diet changes with your vet, especially if your dog has health issues, is on medication, or has a history of food sensitivities. ## Alternatives to consider – Taste of the Wild Pacific Stream: A grain-free option with salmon as the main protein, suitable for dogs with grain sensitivities. It also includes probiotics.
  • Blue Buffalo Life Protection Formula Lamb and Brown Rice: Another lamb-based grain-inclusive formula with added LifeSource Bits for antioxidants. Priced slightly higher.
  • Purina Pro Plan Sensitive Skin & Stomach Salmon & Rice: A popular choice for dogs with sensitive stomachs or skin issues, using salmon and rice for easy digestion.
  • Wellness CORE Grain-Free Lamb & Venison: If you prefer a grain-free, high-protein diet with lamb and venison, this is a premium alternative with no fillers.
  • Merrick Grain-Free Texas Beef & Sweet Potato: For dogs that need a novel protein, this single-source beef option is grain-free and limited ingredient. Choose the food that best fits your dog’s specific needs, and remember to check the current price on Amazon.
