WSAVA-Approved Dog Food: All 13 Brands Scored (2026)

WSAVA does not approve, certify, or endorse any dog food. There is no official "WSAVA-approved" list — the World Small Animal Veterinary Association has never published one, and the phrase is shorthand pet owners and marketers coined, not a credential WSAVA hands out. What WSAVA actually publishes is a five-question rubric that its Global Nutrition Committee asks owners to put to a manufacturer. When someone calls a brand "WSAVA-approved," what they usually mean — often without realizing the distinction — is that the brand answers all five questions in writing.

That distinction is the point of this guide. Below is how all 13 major brands we track score against WSAVA's five manufacturer-quality questions, what each question actually evaluates, and how to run the same check yourself on any brand not covered here.

What Is WSAVA?

WSAVA stands for the World Small Animal Veterinary Association. It's a global federation of veterinary associations that publishes clinical guidelines across companion animal medicine — nutrition, pain management, preventive care, and more.

In 2011, WSAVA published its Global Nutrition Guidelines, which established a framework for evaluating pet food manufacturers beyond what's printed on the label. The guidelines were updated in 2021 and remain the most widely cited veterinary standard for assessing manufacturer quality in commercial pet food.

The key insight behind the WSAVA guidelines: the label alone doesn't tell you enough. A bag of dog food can be formulated to meet AAFCO minimums while still being produced by a company with no nutritional scientists on staff and no quality control infrastructure. WSAVA criteria look behind the label at the organization producing the food.

The 5 WSAVA Questions Every Dog Owner Should Ask

WSAVA's framework is built around five questions. These aren't recommendations; they're screening criteria. A manufacturer that can't answer them confidently is a manufacturer that hasn't invested in the science behind their product.

1. Does the company employ a full-time, board-certified veterinary nutritionist?

Board-certified veterinary nutritionists (Diplomates of the American College of Veterinary Nutrition, or DACVN) are specialists who have completed additional training beyond veterinary school, passed board exams, and maintain continuing education requirements. A company that employs them full-time has those specialists directly involved in formulation and quality review — not just consulting on marketing materials.

This matters because formulating a nutritionally complete diet requires depth that general veterinary training doesn't provide. A company without this expertise is relying on nutritional software and label compliance alone.

2. Does a credentialed formulator design the recipes?

The first question asks whether a company employs a nutritionist at all. This one asks something more specific: who actually designs the recipes, and what are their credentials? A company can keep a veterinary nutritionist on staff for consulting or marketing review while a food scientist with no nutrition-specific credentials does the actual formulation work.

WSAVA's rubric asks manufacturers to name the formulator and their qualifications — ideally a PhD in animal nutrition or a board-certified nutritionist (DACVN, or the European equivalent, ECVCN). A credentialed formulator means the person translating nutritional science into an actual recipe has the training to do it correctly, not just the oversight of someone who does.

3. Does the company conduct AAFCO feeding trials?

There are two ways a dog food can carry the AAFCO "complete and balanced" statement: formulation (calculating that nutrients meet targets based on ingredient analysis) and feeding trials (actually feeding the diet to dogs and measuring outcomes).

Feeding trials are significantly more expensive and time-consuming, which is why many manufacturers skip them. A company that conducts them is putting their product through real-world biological testing — not just paper calculations. WSAVA recommends prioritizing brands that conduct feeding trials.

4. Does the company own and operate its manufacturing plants?

Many dog food brands don't make their own food. They design a recipe and pay a co-packer — a third-party plant that manufactures for multiple brands — to produce it. That arrangement isn't automatically a problem, but it adds a layer between the company that stands behind the bag and the plant actually mixing, extruding, and packaging it.

A brand that owns its manufacturing plants controls its own quality systems end to end: ingredient sourcing, batch testing, sanitation, and recall response all sit inside one organization instead of being negotiated across a contract. WSAVA's rubric treats owned manufacturing as a meaningful signal because it removes a point of failure that co-manufacturing introduces.

5. Does the company run a documented quality-control program?

Formulation and production are different things. A well-designed formula can be compromised during manufacturing — contamination, ingredient substitution, processing errors — if nothing catches the problem before the bag ships. A documented quality-control program means the company tests incoming ingredients, tests finished batches, and can show you the paper trail if you ask.

This is distinct from employing a nutritionist: a brand can have one on staff without running rigorous batch testing, and a brand can run tight QC without a nutritionist involved at every step. WSAVA asks about both because they catch different kinds of failure — one prevents a bad formula, the other catches a good formula gone wrong on the line.

Why WSAVA Matters More Than Star Ratings

Most popular dog food rating sites use an ingredient-penalty system: they award or deduct points based on ingredient quality scores, protein sources, carbohydrate content, and manufacturing location. It's intuitive, but it has a fundamental problem — it doesn't reflect nutritional science.

WSAVA criteria evaluate the organization behind the food, not just the ingredient deck. A food made with premium-sounding ingredients by a company with no nutritional scientists on staff offers less safety assurance than a food from a manufacturer with full-time DACVNs, active feeding trials, and owned manufacturing.

Star ratings also don't personalize. A 5-star food for a 70-pound active Labrador isn't necessarily the right food for a 12-pound senior Cavalier King Charles Spaniel with a chicken sensitivity. WSAVA criteria are a quality floor — they help you eliminate manufacturers who haven't earned trust. The next step is matching the right food to your specific dog.

Which Dog Food Brands Meet WSAVA Criteria in 2026

Of the 13 major brands we track, 5 meet all five WSAVA manufacturer-quality questions outright: Hill's Science Diet, Royal Canin, Purina Pro Plan, Eukanuba, and Iams. The rest fall short on at least one — feeding trials is the most common gap of the five, though which criteria a given brand misses varies. Here's the full breakdown, ranked by criteria met.

Every score above comes from the same five questions covered earlier. A brand can still be a reasonable choice for your dog with a lower score here — WSAVA criteria measure manufacturer investment, not whether a specific recipe fits your dog's life stage, breed, or health history. Use the score as a floor, not a final verdict.

For a full per-question breakdown of any single brand — including which of the five it meets, partially meets, or fails — see is Hill's Science Diet WSAVA-approved, is Purina Pro Plan WSAVA-approved, is Royal Canin WSAVA-approved, is Blue Buffalo WSAVA-approved, or browse every brand's WSAVA score.

How to Vet a Brand That Isn't on This List

The table above covers the 13 brands we track most closely, but WSAVA's rubric works on any manufacturer. Here's how to run the check yourself.

Check the manufacturer's website for:

• A dedicated veterinary nutrition or R&D team page with credentials listed
• Explicit mention of AAFCO feeding trials (not just "AAFCO formulated")
• A statement of who owns and operates the manufacturing plant

Call or email the company and ask:

• "Do you have a board-certified veterinary nutritionist on staff full-time?"
• "Who formulates your recipes, and what are their credentials?"
• "Do you conduct AAFCO feeding trials?"
• "Do you own the plant that makes this food, or is it co-manufactured?"
• "Can you provide a complete nutrient analysis for [specific product]?"

The speed and quality of the response is itself informative. Companies that have invested in nutrition science can answer these questions immediately. Companies that haven't typically redirect to marketing language.

A Note on Grain-Free and Boutique Brands

The FDA's investigation into a potential link between grain-free and boutique dog foods and dilated cardiomyopathy (DCM) began in 2018 and shaped how veterinary nutritionists approached brand recommendations for several years. As of 2026, the science remains inconclusive — no causative mechanism has been definitively established — but the investigation highlighted a specific gap: many grain-free and boutique brands did not employ board-certified veterinary nutritionists and had not conducted AAFCO feeding trials.

That's exactly what the criteria above are built to catch. The brands flagged in the FDA investigation were largely WSAVA non-compliant — not because of their ingredients, but because of their organizational investment in nutritional science.

The lesson isn't "avoid grain-free." It's "apply WSAVA criteria, because ingredient trends don't substitute for scientific rigor."

Summary: How to Apply WSAVA in Practice

1. Start with WSAVA as a filter. Eliminate any manufacturer that can't confirm a full-time nutritionist, a credentialed formulator, AAFCO feeding trials, owned manufacturing, and a documented quality-control program.
2. Then match to your dog's profile. Life stage, breed size, activity level, health conditions, and ingredient sensitivities should drive the final selection.
3. Skip star ratings as a primary signal. Ingredient-penalty scoring doesn't capture manufacturer quality or nutritional expertise.
4. Revisit annually. Manufacturers change. Formulas change. Apply the criteria fresh each time you're evaluating a new food.
