Who Makes Diamond Dog Food and Who Owns the Company?
Diamond dog food is manufactured by Diamond Pet Foods, an American pet food company headquartered in Meta, Missouri. Its corporate name is Schell & Kampeter, Inc., which is why that name may appear in legal notices, copyright statements, business records, or product documentation.
The business began in 1970 when brothers-in-law Gary Schell and Richard Kampeter purchased a former milling company in Meta. Their original goal was straightforward: produce quality pet food at a price ordinary pet owners could afford.
Unlike many well-known pet food brands owned by large publicly traded corporations, Diamond Pet Foods describes itself as a family-owned company and a privately held company. The second generation of the Schell family and Kampeter family continues to own and operate the business.
This distinction answers several related questions:
- Diamond is not owned by Purina.
- Diamond is not a Mars Petcare brand.
- Diamond is not owned by Hill’s Pet Nutrition.
- Diamond Naturals is not an independent manufacturer.
- Schell & Kampeter, Inc. is the corporate owner behind Diamond Pet Foods.
In simple terms, Diamond Pet Foods is the manufacturer and operating business, while Schell & Kampeter, Inc. is the company that owns it.
Who manufactures Diamond dog food?
Diamond Pet Foods manufactures its dry dog food in the United States using company-operated production plants. It develops pet food formulations, purchases ingredients, produces kibble, performs testing, packages finished food, and distributes the products through retailers.
The company is also known in the pet food industry as a co-packer. A co-packer manufactures products for another company or retailer, sometimes using a private-label name rather than the manufacturer’s own brand.
That does not mean every product associated with Diamond is identical. A private-label food may have a different ingredient list, guaranteed analysis, nutrient profile, recipe, price, or quality specification. Sharing a manufacturer does not automatically make two foods interchangeable.
Who owns Diamond Naturals dog food?
Schell & Kampeter, Inc. owns Diamond Naturals through Diamond Pet Foods. Diamond Naturals is one of the company’s proprietary product lines rather than a separate business with a different owner.
The same ownership structure applies to Diamond, Diamond CARE, Diamond Pro89, and Diamond Naturals Grain-Free. These lines serve different nutritional needs, but they belong to the broader Diamond Pet Foods family.
Where Is Diamond Dog Food Made?
Diamond dog food is made in the United States. Current company information identifies seven U.S. manufacturing facilities located in Missouri, South Carolina, California, Arkansas, Kansas, and Indiana.
The facilities are located in:
| Manufacturing location | State | Relevant detail |
| Meta | Missouri | Company headquarters and original manufacturing location |
| Gaston | South Carolina | East Coast production facility |
| Lathrop | California | One of two California manufacturing locations |
| Ripon | California | Additional West Coast production facility |
| Dumas | Arkansas | South-central U.S. manufacturing location |
| Frontenac | Kansas | Manufacturing facility added during company expansion |
| Rushville | Indiana | Newer facility included in the company’s current plant network |
Older articles sometimes say Diamond operates five or six plants. That information may have been accurate when those pages were published, but Diamond’s current corporate material lists seven facilities, including Rushville, Indiana.
Where is Diamond Naturals dog food made?
Diamond Naturals dry dog food is manufactured within Diamond Pet Foods’ U.S. production network. Depending on the recipe, package size, production schedule, and distribution region, one bag may come from a different plant than another.
For example, a Diamond Naturals bag sold in California is not necessarily made at the same facility as a bag purchased in Pennsylvania. The exact plant can often be identified through the production code printed on the package.
Look for a combination of information near the bag’s best-by date:
- Product code
- Production code
- Lot number
- Bag code
- Best-by date
- Plant identifier
- Time stamp
If the code is unclear, contact Diamond Pet Foods and provide the complete sequence exactly as printed. The manufacturer can use that information to identify the production facility and batch.
Is all Diamond dog food made in company-owned facilities?
Public company information is clearest about its dry-food manufacturing network. Diamond states that its products are produced through its U.S. facilities, and its dry dog food is widely identified with those company-operated plants.
Canned formulas require a little more caution. Wet dog food is produced with different equipment and processes than dry kibble, and pet food companies sometimes use a specialized private-label cannery. Manufacturing arrangements can also change over time.
If the origin of a particular wet dog food or canned formula matters to you, check the package statement and ask Diamond about that exact product. Do not assume every dry and wet recipe follows the same production path merely because both carry a Diamond brand name.
Is Diamond and Diamond Naturals the Same Company?
Yes. Diamond and Diamond Naturals are made by the same company: Diamond Pet Foods.
They are separate product lines, however, and should not be treated as the same food. Each line is positioned for different budgets, ingredient preferences, activity levels, and dietary needs.
Diamond dog food
The original Diamond line generally emphasizes balanced nutrition, practicality, performance, and affordability. Its formulas include options for puppies, adult dogs, maintenance needs, and high-energy animals.
Some recipes are designed for athletic dogs, sporting dogs, or working dogs that need additional calories, protein, and fat to support endurance and performance.
Diamond Naturals
Diamond Naturals is positioned as an ingredient-focused line containing combinations of animal protein, vegetables, fruit, whole grains, superfoods, antioxidants, and probiotics.
Available recipes address several life stages and body sizes, including:
- Small-breed puppies
- Large-breed puppies
- Adult dogs
- Small-breed adults
- Large-breed adults
- Senior dogs
- Active or athletic dogs
The exact ingredients vary by formula. “Naturals” in a product name should not replace a careful review of the ingredient panel and nutritional adequacy statement.
Diamond Naturals Grain-Free
Diamond Naturals Grain-Free provides recipes made without traditional grains. These formulas may use ingredients such as peas, lentils, potatoes, sweet potatoes, or other carbohydrate sources.
Grain-free does not automatically mean healthier, lower in carbohydrates, or appropriate for every dog. Pet owners considering a grain-free formula should discuss the decision with a veterinarian, particularly when there is no diagnosed grain sensitivity.
Diamond CARE
Diamond CARE includes specialized, veterinarian-developed formulas for adult dogs with particular dietary needs. Depending on current availability, the line may include recipes intended for sensitive skin, sensitive stomachs, weight management, or other conditions.
A veterinarian-developed formula is not necessarily the same as a prescription diet. Check whether the exact food is intended for general retail feeding or requires veterinary supervision.
Diamond Pro89
Diamond Pro89 is a high-protein formula aimed at performance dogs. The company states that a high proportion of its protein comes from animal sources, supplying amino acids that help maintain muscle.
This line is designed for active dogs that require fuel for hard work, endurance, and peak performance. Its calorie and nutrient density may be unnecessary for a sedentary household dog.
The practical takeaway is that Diamond, Diamond Naturals, Diamond Naturals Grain-Free, Diamond CARE, and Diamond Pro89 share a manufacturer, but their recipes and intended uses are different.
Who Makes Diamond Dog Food for Private Labels?
Diamond Pet Foods has manufactured both proprietary brands and private-label products. In private-label manufacturing, the name on the front of the bag may belong to a retailer or another pet food company, while a separate co-packer physically produces the food.
Names historically connected with Diamond manufacturing or past production records include:
- Kirkland Signature
- 4health
- Canidae
- Natural Balance
- Solid Gold
- Chicken Soup for the Pet Lover’s Soul
- Country Value
- Premium Edge
- Professional
- Apex
This list needs context. It should not be interpreted as proof that Diamond currently manufactures every recipe sold under every listed brand.
Contract manufacturing relationships can change. A brand may use more than one plant, move production to another supplier, or retain a co-packer for only selected recipes. A historical recall notice can prove that a manufacturer produced a particular product at a particular time, but it does not establish the brand’s present-day arrangement.
How to verify a private-label manufacturer
Use the following process when you want to know who made a specific bag:
- Read the manufacturer or distributor statement on the package.
- Record the complete product name and recipe.
- Photograph the product code, lot number, and best-by date.
- Contact the brand and ask which company manufactured that exact lot.
- Ask whether the product was made in a company-owned or third-party facility.
- Keep the original package until your dog has finished the food without a problem.
A label that says “distributed by” does not necessarily identify the physical manufacturer. Likewise, “made for” may indicate that another company produced the food under contract.
What Brands Does Diamond Pet Foods Make?
Diamond Pet Foods’ principal dog food lines include Diamond, Diamond Naturals, Diamond Naturals Grain-Free, Diamond CARE, and Diamond Pro89. The company also produces cat food under several of these names.
Diamond
The core Diamond range includes puppy, maintenance, performance, and high-energy options. These foods generally focus on complete nutrition and practical pricing.
Diamond Naturals
Diamond Naturals includes dry and canned options built around recognizable protein sources and supporting ingredients such as vegetables, fruit, whole grains, superfoods, and probiotics.
Diamond Naturals Grain-Free
This range uses limited or selected protein sources alongside non-grain carbohydrate ingredients. It is marketed toward owners seeking grain-free food or options for certain food sensitivities.
Diamond CARE
Diamond CARE offers specialized nutritional solutions. Because dogs with chronic digestive, dermatological, renal, or weight-related conditions have individual needs, the choice of formula should be made with veterinary guidance.
Diamond Pro89
Diamond Pro89 targets athletic and working dogs. Its formulation prioritizes animal protein, amino acids, muscle maintenance, stamina, and recovery.
Taste of the Wild
Taste of the Wild is also closely associated with Diamond Pet Foods and Schell & Kampeter, Inc. It is marketed as a separate brand family, with recipes featuring distinctive animal proteins, grain-free choices, and ancient-grain formulas.
Taste of the Wild should not be described as the same food as Diamond Naturals. Although the brands may share corporate ownership or manufacturing resources, their formulations, product positioning, packaging, and guaranteed analyses are different.
How Diamond Dog Food Is Manufactured
Dry dog food manufacturing involves more than combining meat and grain in a bag. A commercial pet food manufacturer must control ingredients, formulation, heat processing, sanitation, packaging, and distribution.
Ingredient receiving and testing
The process begins when animal protein, plant protein, grains, fats, vitamins, minerals, amino acids, vegetables, fruit, and other materials arrive at a facility.
Ingredients should be checked against purchasing specifications before entering production. Depending on the ingredient, testing may evaluate:
- Nutritional composition
- Moisture
- Ingredient identity
- Microbial contamination
- Oxidative stability
- Mycotoxins
- Supplier documentation
Grain-related ingredients can be vulnerable to fungal toxins. Diamond says it tests relevant materials for aflatoxin, vomitoxin—also called DON—and fumonisin.
Aflatoxin is a mycotoxin that may occur when certain fungi grow on crops. It is not something consumers can reliably identify by looking at kibble, which makes supplier controls and laboratory testing important.
Pet food formulation
Animal nutrition specialists develop each formula around its intended life stage and purpose. A puppy formula, for example, needs a different nutrient balance from a maintenance food for adult dogs.
A high-protein formula for working dogs may contain more protein, fat, and calories than a weight-management recipe. A food for healthy digestion may include fiber sources, prebiotics, or probiotics.
The formulation determines the intended proportions of:
- Protein
- Fat
- Fiber
- Moisture
- Vitamins
- Minerals
- Essential amino acids
- Fatty acids
- Calories
The actual recipe must consistently deliver the declared guaranteed analysis while remaining suitable for the intended life stage.
Grinding, mixing, and cooking
Dry ingredients are ground to a controlled particle size and mixed according to the recipe. Fats, liquids, meat ingredients, and other components are added at defined stages.
Most dry dog food is cooked through extrusion. The mixture is exposed to moisture, pressure, and heat before being shaped and cut into kibble. Drying then reduces moisture to improve shelf stability.
Heat processing helps control harmful microorganisms, but time and temperature must be managed carefully. Excessive processing can affect heat-sensitive nutrients, which is one reason manufacturers may add selected vitamins after considering expected processing losses.
Coating and probiotic application
After drying and cooling, kibble may receive a coating of fat or natural flavor to improve palatability. Probiotics may also be applied during a controlled post-cooking stage because live cultures can be damaged by high heat.
Diamond states that its dry dog food lines include K9 Strain Probiotics. These beneficial microorganisms are intended to support healthy digestion and immune function. Check the guaranteed analysis for the exact formula rather than assuming every wet and dry product supplies the same amount.
Finished-product testing and packaging
Finished-product testing may include nutritional analysis, microbial screening, moisture evaluation, and comparison with release specifications.
Once approved, the kibble is sealed in coded bags. Those codes support traceability by connecting a finished bag with its formula, production line, facility, time, and lot.
This traceability becomes especially important if a company receives complaints or announces a voluntary recall.
Ingredients and Nutritional Standards
Diamond recipes vary considerably, so no single ingredient description applies to every product. One formula may begin with chicken, while another uses lamb, beef, pork, fish, chicken meal, or a combination of animal ingredients.
Supporting ingredients may include:
- Brown rice, barley, or oatmeal
- Corn or wheat in selected formulas
- Millet, quinoa, chia seed, or grain sorghum
- Sweet potatoes, carrots, spinach, or peas
- Blueberries, raspberries, or cranberries
- Flaxseed or fish oil
- Prebiotic fiber
- Probiotics
- Added vitamins and minerals
Ingredient quality cannot be judged solely by whether an ingredient sounds appealing. Its nutritional function, digestibility, concentration, sourcing, processing, and role within the entire formula also matter.
What AAFCO standards mean
Diamond states that its formulas are designed to meet applicable nutritional requirements. Shoppers should verify this by finding the nutritional adequacy statement on the package.
The Association of American Feed Control Officials develops model regulations, ingredient definitions, and AAFCO nutrient profiles used in the pet food industry. However, AAFCO does not personally test, approve, certify, or endorse individual dog foods. The AAFCO explanation of pet food standards clarifies the organization’s role.
A proper adequacy statement may say that the food is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for a particular life stage. That is more meaningful than a vague marketing phrase such as “premium nutrition.”
FDA standards and pet food
The U.S. Food and Drug Administration regulates animal food under federal law. Pet food must be safe, produced under appropriate conditions, and labeled accurately.
FDA standards and AAFCO nutrient profiles serve different functions. FDA is a regulator; AAFCO develops models and nutritional standards commonly used by regulators and manufacturers.
Neither term proves that a particular recipe is ideal for every dog. A food can meet a recognized nutrient profile while still being unsuitable for an animal with a specific allergy, medical condition, calorie requirement, or intolerance.
Read the guaranteed analysis
The guaranteed analysis reports minimum or maximum levels of selected nutrients. It commonly includes:
- Crude protein minimum
- Crude fat minimum
- Crude fiber maximum
- Moisture maximum
Some Diamond formulas also guarantee probiotics, omega fatty acids, glucosamine, chondroitin, zinc, selenium, taurine, or L-carnitine.
Compare wet and dry foods carefully because their moisture levels differ. Percentages printed on a canned formula cannot be compared directly with dry dog food percentages without converting both to a dry-matter basis.
Diamond Dog Food Recall History
Diamond Pet Foods has had recalls in its history. The most widely discussed event occurred in 2012 and involved potential Salmonella contamination connected with dry pet food produced at the Gaston, South Carolina, facility.
The event expanded beyond one Diamond recipe because the facility also manufactured other products. Public-health investigators linked multiple brands of dry pet food from the plant to an outbreak of Salmonella Infantis infections.
This history explains why names such as Diamond Naturals, Taste of the Wild, Kirkland Signature, 4health, Canidae, Natural Balance, Solid Gold, Apex, Country Value, Premium Edge, Professional, and Chicken Soup for the Pet Lover’s Soul may appear together in older recall reports.
A historical recall does not automatically mean a product on the shelf today is unsafe. It does, however, show why traceability, sanitation, microbial testing, ingredient controls, production codes, and rapid communication matter.
How to check a possible recall
Do not rely only on an old review article or social media post. Recall status can change, and search results may continue displaying outdated pages long after an event has ended.
If you are concerned about a bag:
- Stop feeding it if it smells unusual, looks moldy, contains foreign material, or appears damaged.
- Keep the food and original packaging in a secure place.
- Photograph the lot number, product code, and best-by date.
- Check current FDA recall information.
- Contact Diamond Pet Foods with the complete code.
- Consult a veterinarian if your dog becomes sick.
- Wash bowls, scoops, storage containers, and hands after handling suspected food.
Possible signs of Salmonella infection in dogs can include diarrhea, vomiting, fever, reduced appetite, and unusual tiredness. Some infected animals may show few or no obvious symptoms, while people can be exposed through contaminated food, bowls, surfaces, feces, or handling.
How to Read a Diamond Dog Food Bag
The front of the bag is designed to attract attention, but the back and side panels provide the information needed for a meaningful evaluation.
Product and line name
First, identify the exact range: Diamond, Diamond Naturals, Diamond Naturals Grain-Free, Diamond CARE, or Diamond Pro89.
Do not shorten the name when reporting a problem. “Diamond Naturals Large Breed Puppy Lamb & Rice Formula” is more useful to the manufacturer or veterinarian than simply saying “Diamond food.”
Life-stage statement
Check whether the food is intended for:
- Growth
- Adult maintenance
- All life stages
- Gestation or lactation
- Large-size growing dogs
A puppy formula labeled for all life stages may be nutritionally suitable for adult dogs, but its calorie density may not be ideal for every adult. Large-breed puppies require controlled nutrition to support steady growth.
Ingredient list
Ingredients are generally listed in descending order by weight before cooking. Remember that fresh meat contains substantial moisture, while meals are more concentrated.
Do not assess the entire food from the first ingredient alone. Review the complete protein pattern, fat sources, carbohydrate ingredients, fiber, supplements, calorie content, and nutritional adequacy statement.
Feeding guide
The feeding chart is a starting point rather than a prescription. Actual needs depend on:
- Body weight
- Body condition
- Age
- Activity
- Reproductive status
- Climate
- Treats
- Medical conditions
- Metabolism
Athletic dogs and working dogs may need more energy during periods of hard activity. Less active animals may gain weight if fed according to a high-energy performance chart.
Production and contact information
Keep the bag code and lot number until the food is finished. If you transfer kibble into a container, retain the original package or photograph both sides clearly.
This small habit makes it easier to investigate a suspected quality problem and determine where a particular bag was made.
Is Diamond Dog Food a Good Choice?
Diamond offers a broad range of relatively affordable pet food, but the right choice depends on the individual dog rather than the manufacturer’s name alone.
Consider the following questions:
- Is the formula appropriate for your dog’s life stage?
- Does it provide complete nutrition for long-term feeding?
- Does the calorie level match your dog’s activity?
- Are the protein sources suitable for your dog?
- Has your veterinarian recommended any restrictions?
- Does your dog maintain healthy digestion, skin, coat, stool quality, and body condition on the food?
- Can you buy the formula consistently?
- Is the package undamaged and within its best-by date?
A healthy adult companion dog may need a different formula from a pregnant dog, growing puppy, senior dog, competitive athlete, or dog with food sensitivities.
When to ask a veterinarian
Consult a veterinarian before selecting a diet for a dog with:
- Kidney disease
- Pancreatitis
- Chronic diarrhea
- Suspected food allergy
- Persistent itching
- Obesity
- Diabetes
- Urinary disease
- Poor growth
- Recurrent vomiting
Do not assume a grain-free formula or limited-protein recipe will diagnose or treat a medical condition. Food reactions are often linked to specific protein ingredients, and identifying the trigger may require a structured elimination diet supervised by a veterinarian.
For broader feeding and care information, the Dog Behaviour resource can help owners understand how appetite, routine, stress, and activity influence a dog’s daily habits. You can also explore the main Dog Food section for additional feeding guides and brand-related information.
Diamond dry food compared with refrigerated fresh food
Diamond’s dry formulas are shelf-stable before opening and are generally easier to store than refrigerated food. Owners comparing kibble with products such as Freshpet Dog Food should consider storage, price, calorie density, convenience, and their dog’s individual response.
Refrigerated food requires closer attention to temperature and time after opening. If you use both formats, learn How Long Does Freshpet Last so unused portions are handled safely.
Budget is another practical difference. Kibble is often less expensive per feeding, while the Freshpet Dog Food Cost monthly can vary substantially with the dog’s weight and calorie needs.
Portion comparisons should be based on calories, not the visual volume of food. A guide explaining how much Freshpet to feed dog can help owners avoid treating refrigerated rolls and dry kibble as equal cup-for-cup replacements.
Puppies require especially careful nutritional planning. Before replacing a complete puppy formula with refrigerated food, check Is Freshpet Good for Puppies and confirm that the chosen recipe carries an appropriate nutritional adequacy statement for growth.
How to change formulas safely
Transition gradually over approximately seven to ten days unless your veterinarian gives different instructions.
A simple transition may look like this:
| Transition period | Current food | New food |
| Days 1–2 | 75% | 25% |
| Days 3–4 | 50% | 50% |
| Days 5–6 | 25% | 75% |
| Day 7 onward | 0% | 100% |
Dogs with sensitive digestion may need a slower transition. Monitor stool quality, appetite, vomiting, itching, energy, and body condition during the change.
Conclusion
Diamond dog food is made by Diamond Pet Foods, a family-owned U.S. pet food manufacturer owned by Schell & Kampeter, Inc. Gary Schell and Richard Kampeter founded the company in Meta, Missouri, in 1970, and the Schell and Kampeter families remain connected with its ownership and operation.
Diamond and Diamond Naturals are product lines from the same company, but they are not identical recipes. Diamond also produces Diamond Naturals Grain-Free, Diamond CARE, Diamond Pro89, and other pet food products, while Taste of the Wild is associated with the same broader manufacturer. Diamond’s current U.S. manufacturing network includes facilities in Missouri, South Carolina, California, Arkansas, Kansas, and Indiana.
When choosing a formula, focus on the exact product rather than the brand name alone. Confirm the life-stage statement, ingredient list, guaranteed analysis, calorie content, feeding directions, production code, and your dog’s individual dietary needs. For health conditions, food sensitivities, or unexplained symptoms, ask a veterinarian for personalized advice.
