Ingredients, Recipes & Value for
Our detailed Diamond Naturals dog food review covers ingredient quality, recipe options, pricing, safety history, and how it compares to premium brands in 2026.
Diamond Naturals sits in a crowded middle ground of the dog food market: it promises premium-quality ingredients at a price point significantly below boutique brands. For dog owners trying to balance nutrition with a realistic grocery budget, that positioning is appealing — but it also invites skepticism. Is the ingredient list genuinely competitive, or is it marketing dressed up in earthy packaging?
This Diamond Naturals dog food review breaks down the brand's full product line, examines guaranteed analysis numbers against AAFCO nutrient profiles, reviews the brand's recall history, and compares specific formulas head-to-head with similarly priced competitors. Whether you're considering a switch or just restocking, here's what you need to know before you buy.
Diamond Naturals Brand Overview: Who Makes It and Where
Diamond Naturals is manufactured by Diamond Pet Foods, a family-owned company headquartered in Meta, Missouri. Founded in 1970, Diamond operates multiple company-owned manufacturing facilities across the United States — a notable distinction from brands that co-pack through third-party contractors. Company-owned plants generally allow tighter quality control and faster response to contamination events.
The Naturals line was launched as a step up from Diamond's standard formulas, positioning itself as a "super-premium" product at a mid-tier price. The brand markets its use of "superfoods" (blueberries, kale, chia seeds, quinoa), pasture-raised proteins, and the absence of corn, wheat, and artificial additives.
Diamond Pet Foods also manufactures for several private-label brands and other named brands (Taste of the Wild, Premium Edge, 4Health). This scale gives them purchasing power on ingredients but also means a single facility issue can affect multiple product lines simultaneously — something worth noting when reviewing their recall history.

Diamond Naturals vs. Competitors: Head-to-Head Comparison
To put Diamond Naturals in context, here's how the standard Adult Chicken & Rice formula compares to similarly positioned brands:
| Attribute | Diamond Naturals Adult | Purina Pro Plan Savor | Blue Buffalo Life Protection | Nutro Ultra Adult |
|---|---|---|---|---|
| First Ingredient | Chicken | Chicken | Deboned Chicken | Chicken |
| Crude Protein | 26% | 26% | 24% | 25% |
| Crude Fat | 16% | 16% | 14% | 15% |
| kcal/cup | 353 | 387 | 373 | 332 |
| Price/lb (avg) | $1.15 | $1.50 | $1.75 | $1.65 |
| Grain-Free Option | Yes | Yes | Yes | Yes |
| Added Probiotics | Yes (named strains) | Yes (Bacillus coagulans) | No | No |
| Joint Support Additives | Glucosamine + Chondroitin | Glucosamine | Glucosamine | None listed |
Diamond Naturals consistently undercuts competitors on price per pound while matching or slightly exceeding them on protein and fat percentages. The inclusion of named probiotic strains and dual joint-support compounds at this price point is uncommon — most competitors reserve those additives for their $1.50+/lb formulas.
Recall History and Safety Record
Diamond Pet Foods Recall Timeline
Diamond Pet Foods has experienced several notable recalls. Transparency about these events matters for informed purchasing:
- 2012 — Salmonella Contamination (Major): Multiple Diamond facilities were linked to salmonella outbreaks affecting both pet food and human handlers. This was the brand's most significant safety event, resulting in a voluntary recall of products manufactured at their Gaston, South Carolina facility. The FDA issued a warning and investigation.
- 2013 — Thiamine Deficiency: A limited recall of certain Diamond Naturals kitten formulas (not dog food) due to inadequate thiamine levels.
- 2018 — Potential Salmonella (Precautionary): A single lot of Diamond Naturals Puppy formula was recalled as a precaution after a routine test detected potential salmonella. No illnesses were reported.
Current Status: Since 2018, Diamond has not had any major recalls. The company has invested in upgraded testing protocols and holds SQF (Safe Quality Food) Level 2 certification at its manufacturing facilities — a food-safety standard that goes beyond minimum FDA requirements.
The 2012 salmonella event is important context. It was serious, affected multiple brands manufactured by Diamond, and raised questions about the company's quality control at the time. However, the investments in facility upgrades and third-party food safety certifications since then represent meaningful improvement. No dog food manufacturer has a perfect record — even premium brands like Hill's and Blue Buffalo have had recalls.
Ingredient Quality Analysis: What's Actually in the Bag
Looking at the Adult Chicken & Rice formula's ingredient list in detail:
The Good:
- Chicken as the first ingredient — a whole, named protein source. Note that whole chicken is roughly 70% water, so the actual protein contribution by weight is lower than it appears on the list. However, chicken meal (which appears second) is a concentrated protein source, so the combined protein delivery is solid.
- Named fat sources — chicken fat (preserved with mixed tocopherols) is a quality fat source rich in linoleic acid, an essential omega-6 fatty acid.
- Named probiotic strains — Lactobacillus plantarum, Bacillus coagulans, Bifidobacterium animalis, and Lactobacillus casei are all documented canine-beneficial strains. Many brands list "dried fermentation products" without naming the organisms.
- Whole-food inclusions — blueberries, oranges, kale, spinach, and chia seeds provide phytonutrients and fiber, though their contribution at the inclusion levels present is modest.
The Less Ideal:
- Ground white rice — a high-glycemic carbohydrate. While rice is a perfectly digestible energy source, white rice has less fiber and micronutrient content than brown rice. For diabetic dogs or breeds prone to obesity, this is worth noting.
- Pea protein and pea flour — appearing in the mid-ingredient list, these legume-derived proteins boost the overall crude protein percentage. They're not harmful, but they make the protein number look more meat-heavy than it actually is. This practice (sometimes called "protein spiking" with plant proteins) is common across the industry.
- Dried yeast — listed as a protein supplement and B-vitamin source. Some dogs have yeast sensitivities, though this is uncommon.
Grain-Free Formulas and the FDA DCM Investigation
If you're considering the Diamond Naturals Grain-Free line, you should be aware of the FDA's ongoing investigation into a potential link between grain-free diets and dilated cardiomyopathy (DCM) in dogs.
The FDA has identified a correlation between DCM cases and diets high in peas, lentils, chickpeas, and potatoes as primary ingredients — ingredients that replace grains in grain-free formulations. Diamond Naturals Grain-Free formulas do contain peas, lentils, and chickpeas.
As of 2026, the FDA has not established a definitive causal mechanism, and the investigation continues. The American Veterinary Medical Association has noted that the vast majority of dogs do not have grain allergies (estimated at less than 1% of the canine population) and that grain-inclusive diets remain the safer default choice unless a veterinarian has diagnosed a specific grain allergy.
Bottom line: Unless your vet has confirmed a grain allergy through an elimination diet trial, the grain-inclusive Diamond Naturals formulas are the more conservative choice.
How to Transition Your Dog to Diamond Naturals
7-Day Transition Protocol
Sudden diet changes cause gastrointestinal upset in most dogs. Follow this gradual transition schedule:
- Days 1–2: 75% current food + 25% Diamond Naturals. Mix thoroughly so your dog can't sort out the old food.
- Days 3–4: 50% current food + 50% Diamond Naturals. Monitor stool consistency — soft stools are normal during transition but should not be watery.
- Days 5–6: 25% current food + 75% Diamond Naturals. If stools remain firm, proceed. If loose, hold at this ratio an extra day.
- Day 7: 100% Diamond Naturals.
Feeding Amount Guide (Adult Chicken & Rice):
| Dog Weight | Daily Amount | Estimated Daily Cost |
|---|---|---|
| 10–20 lb (4.5–9 kg) | ¾ – 1¼ cups | $0.30 – $0.50 |
| 20–40 lb (9–18 kg) | 1¼ – 2 cups | $0.50 – $0.80 |
| 40–60 lb (18–27 kg) | 2 – 2⅔ cups | $0.80 – $1.07 |
| 60–80 lb (27–36 kg) | 2⅔ – 3⅓ cups | $1.07 – $1.33 |
| 80–100 lb (36–45 kg) | 3⅓ – 4 cups | $1.33 – $1.60 |
These are starting points. Adjust based on your dog's body condition score (BCS) — you should be able to feel ribs without pressing hard, and see a defined waist from above.
Where to Buy Diamond Naturals and Current Pricing
Diamond Naturals is widely distributed, which contributes to competitive pricing:
- Chewy.com: Often the lowest price, with Subscribe & Save discounts of 5–10%. 35 lb Adult Chicken & Rice typically $37–$42.
- Amazon: Variable pricing, often $40–$48. Watch for third-party sellers — always verify "sold by Amazon" or the official Diamond storefront to avoid expired stock.
- Tractor Supply Co.: Common in-store stock, typically $38–$45. Good option for rural owners who want to avoid shipping.
- Independent pet stores: Some carry Diamond Naturals, often at slightly higher prices ($42–$50) but with the advantage of supporting local businesses and getting personalized guidance.
- Walmart (online): Available through Walmart.com marketplace, pricing varies by seller.
For a 60 lb (27 kg) dog eating roughly 2.5 cups per day, a 35 lb bag lasts approximately 22–25 days, putting monthly feeding costs at roughly $45–$55. This compares favorably to premium brands like Orijen ($85–$110/month for the same dog) or Royal Canin ($65–$85/month).
When to Skip Commercial Food and See Your Veterinarian
No commercial dog food is appropriate if your dog shows any of the following signs. Consult your veterinarian before continuing or changing any diet:
- Chronic loose stools or diarrhea lasting more than 48 hours after completing a diet transition
- Vomiting after meals — especially if repeated or accompanied by lethargy
- Unexplained weight loss despite adequate caloric intake
- Excessive itching, hot spots, or ear infections — potential food allergy indicators that require a veterinary-supervised elimination diet trial, not a simple brand switch
- Decreased appetite lasting more than 24 hours in an adult dog
- Signs of bloat (GDV) — distended abdomen, unproductive retching, restlessness. This is a life-threatening emergency; go to the nearest emergency veterinary hospital immediately.
If your dog has diagnosed conditions such as kidney disease, liver disease, diabetes, or pancreatitis, they likely require a veterinary therapeutic diet (e.g., Hill's Prescription Diet, Royal Canin Veterinary Diet, Purina Pro Plan Veterinary Supplements) rather than any over-the-counter commercial food, regardless of brand quality.
Alternatives to Diamond Naturals
If Diamond Naturals doesn't fit your dog's needs, here are alternatives across different categories:
Similar Price Point, Different Protein Sources:
- Purina Pro Plan Savor Adult: Comparable nutrition with wider flavor variety and a longer track record of feeding trials.
- Iams ProActive Health Adult: Slightly lower protein (25%) but very well-tolerated by most dogs, widely available.
Step Up in Price ($1.50–$2.00/lb):
- Fromm Family Gold Adult: Family-owned, smaller-batch production, rotating protein options.
- Victor Hi-Pro Plus: Excellent for active and working dogs, 30% protein, very high palatability.
Premium/Super-Premium ($2.00+/lb):
- Orijen Original: 85% animal ingredients, biologically appropriate ratios, but significantly higher cost.
- Acana Red Meat: Regionally sourced ingredients, high meat inclusion, moderate price within the premium tier.
Homemade/Fresh Food Alternatives:
- The Farmer's Dog, Nom Nom (now part of Mars): Fresh-delivered, human-grade cooked meals. Excellent ingredient quality but $5–$10/day for a 60 lb dog.
- Consult a board-certified veterinary nutritionist (ACVN diplomate) if you want to prepare a complete homemade diet long-term. Recipes from unverified internet sources frequently cause nutrient deficiencies over time.
Frequently Asked Questions
Is Diamond Naturals a good dog food brand overall?
Diamond Naturals delivers solid nutrition at a competitive price. Its ingredient quality — named proteins, named probiotic strains, and joint-support additives — punches above its price class. It's not a premium brand, and it uses some cost-saving ingredients (ground white rice, pea protein), but it meets AAFCO standards and provides reliable nutrition for most healthy adult dogs. For owners who want better-than-grocery-store quality without premium pricing, it's a strong option.
Has Diamond Naturals ever been recalled?
Yes. The most significant event was a 2012 salmonella recall linked to their Gaston, SC facility. A precautionary puppy formula recall occurred in 2018 with no reported illnesses. Since 2018, there have been no recalls, and the company has invested in SQF Level 2 facility certifications and enhanced testing protocols.
Is Diamond Naturals grain-free safe for my dog?
The FDA has investigated a potential link between grain-free diets (specifically those high in peas, lentils, and potatoes) and dilated cardiomyopathy (DCM). Diamond Naturals Grain-Free formulas contain these legume ingredients. Unless your veterinarian has confirmed a grain allergy, the grain-inclusive formulas are the safer choice. Most dogs tolerate grains well, and grains like rice and barley provide beneficial fiber and nutrients.
How does Diamond Naturals compare to Taste of the Wild?
Both brands are manufactured by Diamond Pet Foods. Taste of the Wild is positioned at a slightly higher price point ($1.30–$1.70/lb) and features more exotic proteins (bison, wild boar, venison). Nutritionally, they're comparable. Taste of the Wild is also entirely grain-free, which may be a concern given the FDA DCM investigation. Diamond Naturals grain-inclusive formulas offer a safer default option at a lower cost.
What if my dog won't eat Diamond Naturals?
Palatability varies by individual dog. Diamond Naturals is generally well-accepted, but some dogs prefer higher-fat formulas. Try topping with a tablespoon of warm water, low-sodium bone broth (no onion or garlic), or a small amount of plain canned pumpkin. If your dog consistently refuses multiple formulas, consult your veterinarian to rule out underlying health issues affecting appetite.
Can I mix Diamond Naturals with wet food or raw food?
You can mix Diamond Naturals kibble with wet food from the same brand to increase palatability and moisture intake. Mixing with raw food is more controversial — the AVMA discourages raw feeding due to documented pathogen risks (Salmonella, Listeria) for both pets and human household members. If you choose to supplement kibble, adding plain cooked chicken, scrambled eggs, or steamed vegetables is a safer approach than raw meat.
Disclaimer: This review is based on publicly available ingredient lists, guaranteed analysis data, and recall records. Individual dogs may respond differently to any diet. Always consult your veterinarian before making significant changes to your dog's nutrition plan, especially for dogs with health conditions, puppies, or senior dogs.
