Reviewed by the FAMMO Veterinary Nutrition Team · Sources: Pet Nutrition Alliance, WSAVA, ACVN

💡 Quick Answer: The 2023 Pet Food Manufacturer Evaluation Report by the Pet Nutrition Alliance helps pet parents see which pet food companies are more transparent behind the label. It looked at whether manufacturers employ qualified nutrition experts, control their own production, and share safety or quality-control data. Hill’s, Purina, and Royal Canin showed stronger transparency signals, while some well-known brands, including Diamond Pet Foods and Farmina, did not provide complete responses in the report.

Introduction: Why Pet Food Brand Transparency Matters More Than Ever

Choosing the right food for your pet is no longer just about reading the ingredient list.

A bag of food may look premium, natural, holistic, or veterinarian-approved, but those words do not always tell you who formulated the recipe, where the food was manufactured, or whether the company shares real quality-control data.

That is why the foundational Pet Food Manufacturer Evaluation Report 2023 by the Pet Nutrition Alliance became such an important reference for pet parents, veterinarians, and nutrition-focused brands.

Rather than relying on packaging claims, the report looked behind the label. It examined how pet food companies operate, who formulates their products, whether they own their manufacturing plants, and whether they employ qualified veterinary nutrition experts.

For proactive pet parents, this evaluation provides a rare window into the quality, accountability, and transparency signals behind popular pet food brands.

In this guide, we break down the core findings of the 2023 report, explain what they mean for pet parents in 2026, and show how data-driven tracking can help you understand whether a food actually fits your dog or cat.

Why the Pet Food Manufacturer Evaluation Report Matters

Most pet food labels are designed to build trust.

They highlight words like natural, premium, holistic, or veterinarian-approved. But these claims do not always answer the questions that matter most: who formulated the food, where it was made, how it was tested, and whether the company is transparent about quality control.

That is why the Pet Food Manufacturer Evaluation Report 2023 matters.

Instead of judging brands by packaging or marketing language, the report helps pet parents look at the operational side of pet food companies, the part most people never see.

The report focuses on three core transparency questions:

• Formulation expertise: Does the company employ qualified veterinary nutrition experts, such as board-certified veterinary nutritionists or PhD-level animal nutrition specialists?

• Manufacturing control: Does the brand own its manufacturing facilities, or does it rely on third-party production partners?

• Quality and safety transparency: Does the company share meaningful information about testing, feeding trials, quality-control procedures, and nutritional standards?

For pet parents, this matters because a beautiful label does not always mean a better food.

A brand that invests in nutrition expertise, manufacturing control, and transparent testing gives you stronger signals of accountability. It does not guarantee that one food is perfect for every dog or cat, but it gives you a better starting point than marketing claims alone.

Once you choose a more transparent, science-backed food, the next step is monitoring how that food actually affects your pet. Weight, digestion, appetite, stool quality, energy, and body condition all matter.

For example, if you are changing your cat’s diet to manage weight, brand transparency is only the first step. You also need to track real progress over time. Our guide on how to tell if your cat is overweight explains the body-condition signs pet parents should watch, while FAMMO’s AI tracking tools help turn those daily signals into clearer nutrition insights.

Pet Food Brand Transparency Comparison

The Pet Food Manufacturer Evaluation Report 2023 does not simply rank brands by popularity. It looks at whether companies provide clear answers about formulation expertise, manufacturing control, and safety or quality-control standards.

Here is a simplified comparison of several well-known pet food manufacturers mentioned in the report:

This comparison does not mean non-responding brands are automatically unsafe. It shows which companies provided clearer transparency signals when independently evaluated.

For pet parents, the practical takeaway is this: do not choose food based only on packaging claims. Look for evidence of qualified formulation, manufacturing control, safety testing, and clear communication from the brand.

The Future of Pet Food Manufacturing: Data Over Marketing

The findings of the 2023 Pet Food Manufacturer Evaluation Report show that transparency is becoming one of the most important trust signals in pet nutrition.

In the past, many pet food decisions were shaped by packaging claims, emotional branding, and broad promises such as “premium,” “natural,” or “complete and balanced.” But as pet parents become more informed, the future of pet food is moving toward something much clearer: verifiable data.

By 2026, the strongest pet food brands will not only need to explain what is inside the bag. They will also need to show how the food was formulated, where it was made, how it was tested, and how it performs in real pets over time.

This is where manufacturing transparency and pet health tracking start to connect.

A transparent manufacturer can explain the quality standards behind a product. But data-driven tools can help pet parents understand whether that product is actually working for their individual dog or cat.

Here is how the future of pet food manufacturing and nutrition is changing:

• Predictive health signals over reactive care:
  Nutrition, appetite, digestion, body weight, stool quality, and daily energy can all reveal early changes in a pet’s wellbeing. These signals do not automatically mean disease, but they are worth tracking. To understand this shift, read our guide on how AI can detect early health signals in pets.

• Manufacturing transparency signals:
  Future-focused pet food brands may provide clearer access to batch-level testing, ingredient sourcing, quality-control standards, and manufacturing information. QR codes, digital product pages, and transparent lab data could become more important as pet parents demand proof behind the label.

• Personalized nutrition instead of average formulas:
  Generic pet food formulas are designed for broad life stages, but no two pets are exactly the same. Age, breed size, weight, activity level, digestion, appetite, and health background all affect what “the right food” means. For a deeper look at this shift, read our guide on AI personalized pet diets in Europe.

The future of pet food will not be decided only by better marketing. It will be shaped by clearer manufacturing data, stronger quality standards, and tools that help pet parents track how food affects real pets in real life.

Key Findings from the 2023 Report (And What They Mean Today)

1. The Role of Qualified Nutritionists

One of the most important evaluation criteria is whether pet food manufacturers employ qualified nutrition experts. Formulating a complete and balanced diet requires scientific precision, not just mixing ingredients or following marketing trends.

The report looked for the presence of:

• PhD-level animal nutritionists
• DACVIM (Nutrition) or ECVCN board-certified specialists
• Consulting veterinarians with advanced nutrition training

Industry Examples:

• ✅ Hill’s Pet Nutrition: Employs DACVIM-certified nutritionists and PhDs.
• ✅ Mars Petcare (Royal Canin, Pedigree, Whiskas): Employs DACVIM/ECVCN specialists, PhDs, and MS-level nutritionists.
• ✅ Champion Petfoods (Orijen, ACANA): Employs PhD and MS-level nutritionists.
• ❌ Canisource Grand Cru: Does not employ MS, PhD, or DACVN nutritionists.

The Takeaway: The presence of qualified professionals is one of the strongest transparency signals for scientific formulation, nutritional adequacy, and quality-focused product development.

2. Manufacturing Ownership: Who Controls the Quality?

The report also evaluates whether brands own their manufacturing plants or rely entirely on third-party co-packers.

• 100% Plant Ownership: Mars, Nestlé Purina, Cargill, Primal Pet Group.
• Partial Ownership: Blue Buffalo (80%), Champion Petfoods (95%).
• 0% Ownership: Annamaet, Evermore Pet Food, Nulo, Pet Plate.

Why it matters: Owning manufacturing facilities can give companies stronger oversight over quality assurance, ingredient sourcing, and safety protocols.

Outsourcing to third-party plants does not automatically mean poor quality, but it can make manufacturing oversight harder to evaluate unless the brand shares clear quality-control and testing information.

3. Transparency: Who Responded vs. Who Stayed Silent

In the pet nutrition space, transparency is one of the strongest trust signals. The Pet Nutrition Alliance reached out to pet food companies directly to understand how much information they were willing to share about formulation, manufacturing, and quality-control practices.

While many brands provided detailed information, several popular companies either declined to respond or did not provide complete answers.

• Provided stronger transparency signals: Hill’s, Purina, Mars, Blue Buffalo, Instinct.

• Did not respond: Diamond Pet, Farmina, Freshpet, Stella & Chewy’s, Weruva.

• Declined to respond: Life’s Abundance, Trader Joe’s, Stewart Raw Naturals.

Pro Tip for Pet Parents: Transparency in manufacturing is just as important as the ingredients on the label. Brands that do not share clear safety and quality-control information give pet parents fewer trust signals to evaluate.

Regional Note: Using Transparency Signals in Europe

European pet parents often compare brands across markets such as France, the Netherlands, Germany, and the UK. Availability changes by country, but the evaluation method stays the same.

Before choosing a food, look for the same trust signals: qualified nutrition expertise, clear manufacturing information, safety testing, feeding guidance, and transparent communication from the brand.

What This Means for Proactive Pet Parents

1. Look Beyond the “Holistic” Hype

Fancy packaging and marketing buzzwords like “human-grade,” “holistic,” or “ancestral” do not guarantee nutritional adequacy. What truly matters for your pet’s longevity is rigorous scientific formulation and AAFCO-compliant testing.

2. Prioritize Veterinary Formulation

Companies that employ board-certified veterinary nutritionists (DACVIM) or PhDs are actively investing in your pet’s long-term health. They ensure the diet meets specific metabolic needs rather than just hitting basic protein targets.

3. Demand Total Transparency

If a pet food brand refuses to disclose fundamental manufacturing data, safety protocols, or nutritional testing results, consider it a massive red flag. Your pet’s health deserves better than a guessing game.

4. Understand the Hidden Risks of Co-Packing

Brands that outsource production to third-party plants (co-packers) inherently have less oversight over ingredient sourcing. Owning the manufacturing plant ensures strict quality control and drastically reduces the risk of dangerous cross-contamination.

The Ultimate Pet Food Buyer’s Checklist

Next time you are evaluating a new diet or transitioning your pet to a different brand, run it through this science-backed checklist:

• [ ] Who formulated this exact recipe? (Look for DACVIM or PhD credentials).

• [ ] Does the brand own its manufacturing facility?

• [ ] Are their feeding trials and safety data publicly available?

• [ ] Does this specific formula match my pet’s current life stage and weight goals?

By utilizing the insights from the Pet Food Manufacturer Evaluation Report, you are finally making dietary choices based on science, not slogans.

Frequently Asked Questions

1. What is the Pet Food Manufacturer Evaluation Report?

It is a comprehensive, independent audit conducted by the Pet Nutrition Alliance. The report evaluates pet food brands based on clinical standards, specifically looking at whether they employ board-certified veterinary nutritionists, own their manufacturing plants, and maintain strict quality control and transparency.

2. Which pet food brands showed stronger transparency in the report?

Based on the information provided in the report, brands such as Hill’s Pet Nutrition, Royal Canin / Mars Petcare, and Nestlé Purina showed stronger transparency signals because they reported qualified nutrition expertise, manufacturing control, and safety or quality information. This does not mean they are the best choice for every pet, but they provide more information for pet parents to evaluate.

3. Should I avoid pet food brands that did not respond to the report?

Not automatically. A lack of response does not prove that a food is unsafe. However, it does give pet parents less information to evaluate the company’s nutrition expertise, manufacturing control, and safety testing. If you use a brand with limited public information, monitor your pet’s weight, digestion, appetite, and energy carefully.

4. Is grain-free or “holistic” pet food actually healthier?

Not necessarily. Clinical research and evaluation reports indicate that rigorous scientific formulation (ensuring the correct balance of amino acids, taurine, and vital nutrients) is far more critical than marketing buzzwords like “grain-free” or “holistic.” In fact, replacing grains with heavy legumes has been investigated by the FDA for potential links to heart issues in pets.

5. How can I ensure I am feeding my pet the absolute best diet?

First, look beyond the packaging. Choose brands that employ DACVIM nutritionists, own their plants, and conduct thorough AAFCO feeding trials. Second, verify the results with data. By logging your pet’s daily meals and weight into FAMMO’s AI-driven health tracker, you can visually monitor their growth curve and ensure the food is perfectly optimizing their unique metabolism.

6. Which pet food brands are recommended for pet owners in Europe?

For European pet owners, brands like Royal Canin (France), Hill’s Pet Nutrition, and Nestlé Purina consistently meet clinical transparency standards across all three evaluation criteria. They comply with FEDIAF nutritional guidelines and employ board-certified nutritionists. For budget-conscious pet owners, large manufacturers like Purina offer affordable lines without sacrificing formulation quality.

Conclusion: From Industry Data to Daily Action

The foundational 2023 Pet Food Manufacturer Evaluation Report served as a massive wake-up call for the industry, and its lessons are more critical now than ever. It definitively proved that not all brands prioritize science, transparency, or your pet’s safety.

By utilizing these insights, seeking out board-certified nutritionists, demanding manufacturing transparency, and ignoring “holistic” marketing hype, you have already taken the first major step in protecting your pet’s health.

But choosing the right food is only half the equation. Knowing exactly how it impacts your pet is the other.

Even the highest-rated clinical diet can cause weight fluctuations, digestive changes, or energy dips if it doesn’t align perfectly with your pet’s unique metabolism. You can’t manage what you don’t measure.
