Diamond Dog Food: Quality You Can Trust – Diamond Naturals

Diamond Naturals (often called diamond dog food) has built a reputation on premium ingredients and rigorous quality control. As a family-owned brand since 1970, Diamond Pet Foods offers dog formulas enriched with real meat proteins, superfoods, and guaranteed probiotics. In this article, we’ll explore what makes Diamond Naturals dog food a trusted choice: from its nutrient-rich ingredients to its strict safety standards and how it compares to other popular brands like Nutro and Eukanuba. Ultimately, you’ll see why many pet owners consider Diamond Naturals one of the best dry dog food options on the market.

Diamond Naturals All Life Stages Chicken & Rice Formula packaging. This dog food features real cage-free chicken as the first ingredient, plus added superfoods and probiotics.

Diamond Naturals takes a holistic approach: each formula is crafted to support overall health and wellness. Every Diamond dog food recipe includes beneficial K9 Strain Probiotics (80 million CFU per pound) for digestive and immune support, plus a variety of nutrient-rich “superfoods” like kale, spinach, and blueberries. High-quality animal proteins (cage-free chicken, pasture-raised lamb, beef, or wild salmon) form the base of the formulas, providing energy and muscle-building nutrients. Together with an array of vitamins and minerals from fruits and vegetables, these ingredients help keep dogs active, healthy, and thriving.

Premium Ingredients & Nutrition

Diamond Naturals formulas stand out for their real-food ingredients. For example, the All Life Stages Chicken & Rice formula lists cage-free chicken and chicken meal as the first ingredients. Throughout the product line, you’ll find:

• High-Quality Proteins: Real meat (chicken, lamb, beef or salmon) is always the #1 ingredient, supplying essential amino acids for healthy muscles. Pasture-raised lamb and beef provide energy and strength, while chicken delivers a classic meaty flavor dogs love.
• Omega Fatty Acids: Diamond adds fish oils (salmon oil) and seeds (flaxseed, chia) to ensure a healthy fat profile. Salmon oil provides DHA and Omega-3s, key for puppy brain/eye development and for a shiny coat in adults. In fact, the Skin & Coat Salmon & Potato formula uses real wild salmon as the first ingredient, delivering omega-3s and vitamin-rich oils.
• Superfoods & Antioxidants: Bright fruits and veggies—kale, spinach, carrots, blueberries, oranges, pumpkin, papaya—are added for their vitamins, minerals, and antioxidants. These ingredients help support the immune system and overall vitality. A Diamond recipe might include kale, quinoa, chia seed, or blueberries in every bag.
• Joint & Bone Support: Many adult formulas include guaranteed glucosamine and chondroitin for joint health. This is especially beneficial for large breeds and senior dogs needing extra joint support as they age.
• No Fillers: Unlike lower-end kibbles, Diamond formulas contain no corn, wheat, or artificial preservatives. Owners note Diamond “has no Corn, Wheat or Soy” and instead uses whole grains (rice, barley) and natural fibers. By avoiding cheap fillers, Diamond provides dense nutrition in every cup.
• Formulated to AAFCO Standards: All Diamond Naturals products meet the nutritional levels established by AAFCO for their intended life stage. This means your dog’s diet from puppyhood through adulthood is complete and balanced.

In summary, Diamond dog food formulas combine protein-rich recipes with nutrient-dense plant ingredients. As WagWalking’s expert review notes, “recipes include protein and superfoods plus there are no fillers,” making Diamond Naturals a good dog food choice. Whether your dog is a playful puppy or a laid-back senior, Diamond offers options tailored to each life stage, size, and activity level.

Guaranteed Probiotics for Digestive Health

A signature feature of Diamond Naturals is its probiotic guarantee. Every dry formula contains K9 Strain Probiotics—beneficial bacteria developed specifically for dogs. These probiotics are added after baking to ensure potency. In fact, Diamond guarantees at least 80 million live CFUs per pound of food. Probiotics help maintain a healthy gut flora, improving digestion and immune response. For pet owners concerned about gut health or sensitive stomachs, this is a standout benefit.

According to Diamond’s site, these K9 strain probiotics “support digestive and immune systems and help your dog maintain an active lifestyle”. Independent reviewers also note Diamond’s probiotic focus: each recipe “is enhanced with guaranteed probiotics”. Over time, strong digestive health leads to better nutrient absorption and fewer tummy upsets.

Quality Assurance & Manufacturing Standards

When we say quality you can trust, Diamond backs it up with stringent safety protocols. Diamond Pet Foods employs a comprehensive food safety system in every step of production. Some highlights:

• Rigorous Testing: Diamond performs thousands of tests weekly on ingredients and finished products. For example, every week they run 3,458 mycotoxin tests on grains and 1,538 microbiological tests on raw and cooked materials. Before any food ships, over 40,095 nutritional tests are completed on finished batches. No product is released without passing these tests.
• Air & Water Purity: Manufacturing facilities use HEPA air filtration and reverse-osmosis water purification to eliminate contaminants. Raw materials are separated from finished products by zone to prevent cross-contamination.
• Strict “Test and Hold”: Finished bags sit in quarantine until outside labs verify safety and nutrient levels. Diamond’s Test and Hold Program ensures every bag meets label guarantees.
• Made in the USA: All Diamond Naturals formulas are produced in Diamond’s six U.S. plants (Missouri, South Carolina, Arkansas, Kansas, and California). Domestic production allows tighter quality control and traceability.

These procedures echo the brand’s motto: “nothing is more important… than the safety of our ingredients and products.”. As one retailer notes, Diamond Naturals is “manufactured in a facility with stringent quality controls… deliver[ing] a product you can feel confident feeding”. In short, Diamond dog food isn’t just about good ingredients—it’s about ensuring those ingredients stay pure from source to bowl.

Diamond vs. Other Top Dog Food Brands

Diamond Naturals compares favorably with other premium dog foods, each with its own focus:

• Nutro Dog Food: Like Diamond, Nutro markets itself on natural, wholesome recipes. Nutro states its dry foods are made with “wholesome, natural ingredients” to nourish pets. Nutro’s Ultra line uses a trio of proteins (chicken, lamb, salmon) and includes antioxidants while excluding fillers. For example, the Nutro Ultra Adult Superfood Plate is “made with real chicken as the #1 ingredient” and has “no corn, wheat or soy”. Both brands emphasize quality protein and plant-based nutrients, but Diamond adds guaranteed probiotics to the mix, which Nutro does not promise. Nutro also highlights non-GMO ingredients (a feature not explicitly claimed by Diamond). In practice, both Diamond and Nutro offer grain-inclusive and grain-free options, rich in protein and superfoods.
• Eukanuba Dog Food: Eukanuba (by Mars/Purina) positions itself for athletic dogs and performance. The Eukanuba site emphasizes “premium performance” formulas that are “scientifically formulated” for peak endurance. Their diets often have very high protein/fat (e.g. 30%/20% in sport formulas) and added joint support (glucosamine/chondroitin). In fact, Dog Food Advisor notes Eukanuba’s adult line “provides a majority of its protein from chicken” plus glucosamine and chondroitin for agile joints. In contrast, Diamond Naturals is more of an all-purpose, holistic line (it even has a formula named Extreme Athlete for active dogs). If your dog needs high-octane sport nutrition, Eukanuba is targeted for that. However, Diamond’s broad focus on gut health (probiotics), diverse superfoods, and family-oriented values can appeal more to owners seeking well-rounded daily nutrition.
• Salmon-Based Dog Foods: For dogs that benefit from fish protein (sensitive stomachs or skin issues), salmon dog food is important. Diamond Naturals offers the Skin & Coat Salmon & Potato formula with real salmon as its first ingredient, providing omega-3s and nutrients like B12 and vitamin D. Other brands (like Merrick or Purina) have salmon recipes too, but Diamond’s unique addition is the guaranteed probiotics and superfood mix in that salmon diet. So if you search “best dry dog food” for salmon, Diamond’s salmon formula often ranks high because of its balanced blend of fish oil, fiber, and antioxidants.
• Best Dry Dog Food Rankings: Independent reviewers often rate Diamond well. DogFoodAdvisor, a respected review site, gives the Diamond Naturals line an overall average of 4.5 out of 5 stars. In their review of 13 Diamond recipes, no formula was banned or flagged – most were rated 4 or 5 stars. This compares favorably with many big brands. In budget-friendly comparisons, reviewers praise Diamond for its ingredient quality and family ownership.

In summary, Diamond Naturals holds its own against Nutro, Eukanuba, and other brands. It may not specialize solely in performance (like Eukanuba) or claim non-GMO sourcing (like Nutro), but it combines many advantages: high protein, superfood nutrition, digestive support, and rigorous safety. For many owners, that blend of benefits places Diamond among the top dry dog foods in overall value.

Expert & Customer Opinions

What do experts and dog owners say about Diamond Naturals? The consensus is largely positive:

• WagWalking Review: WagWalking.com gave Diamond Naturals a high “paw” rating. Their review notes that Diamond’s philosophy is “high-quality food at an affordable price”. They affirm “Diamond Naturals is good dog food,” highlighting its protein and superfood content with “no fillers”. The review also mentions real meat and fish as first ingredients and a variety of formulas (grain-inclusive or grain-free) for all breeds. A Wag editor explains this rating is based on ingredients and nutrition, suggesting strong overall performance.
• DogFoodAdvisor: This independent site compiles reviews and ratings from vets and nutritionists. As mentioned, they rated 13 Diamond formulas from 2.5 to 5 stars, averaging 4.5 stars overall. Their ingredient analysis notes the inclusion of many healthy components (salmon oil, kale, blueberries) and only a few controversial items (like yeast or beet pulp) in the All Life Stages Chicken & Rice formula. Importantly, they recognize Diamond’s use of whole foods and probiotics as positives, calling it a “holistic approach.”
• User Reviews: Many dog owners praise Diamond Naturals. For example, one German Shepherd owner wrote: “I especially like that there is no corn, wheat or soy in this kibble, and that there is whole grains like chia seeds, quinoa, and fruits and vegetables like blueberries and kale. The Shepherds had no gastrointestinal problems… They love it!”. Another owner noted their picky senior dog adjusted well to Diamond after switching: “She LOVED it. No upset belly, no vomiting and she chows it down.”. These anecdotes reinforce that real pet parents see tangible results: healthy coats, happy tummies, and enthusiastic eaters.
• Professional Endorsements: Veterinarians and pet nutritionists often recommend Diamond for value-oriented quality. A common refrain is that Diamond offers “trusted nutrition” – it meets AAFCO profiles and uses carefully selected ingredients. While it’s not marketed as a vet-exclusive brand, its transparent ingredient lists and emphasis on added nutrients (DHA, joint supplements, probiotics) align with what vets look for in good pet diets.

In short, both data and reviews suggest Diamond Naturals delivers on its promises of quality and trust. Whether it’s high ratings on review sites or happy customer testimonials, the feedback tends to highlight the very qualities Diamond advertises.
