We Analyzed 200 Pet Foods with Voyage AI Vet — Here's What We Found

We ran 200 of the most popular pet foods through Voyage's nutrition scanner, scoring each against the WSAVA framework for evaluating pet food quality. Nearly half scored below threshold, price often did not predict quality, and marketing terms like "natural" and "holistic" had almost no correlation with actual nutritional adequacy.

Last reviewed: May 2026

Pet nutrition is one of the highest-stakes daily decisions an owner makes — and one of the least transparent. Bag-front marketing emphasizes ingredients you recognize ("real chicken!", "natural!", "grain-free!"), while the metrics that actually predict nutritional quality — guaranteed analysis, AAFCO statement, manufacturer transparency, calorie density — sit in fine print on the back. We wanted to know whether the foods owners actually buy meet the standards veterinary nutritionists use to evaluate them. So we ran 200 of the most popular brands through Voyage's nutrition scanner.

The Framework: How Veterinary Nutritionists Actually Evaluate Pet Food

The widely-used framework comes from the WSAVA Global Nutrition Guidelines and their Selecting a Pet Food toolkit, 2021. The framework asks five questions that most pet food bag-front marketing dodges:

1. Does the manufacturer employ a full-time qualified nutritionist (PhD in nutrition or board-certified veterinary nutritionist)?
2. Where are the foods manufactured — and who owns those facilities?
3. Does the manufacturer publish complete nutrient analysis on request, not just the guaranteed analysis on the bag?
4. Does the food carry an AAFCO statement of nutritional adequacy ("complete and balanced for…") for the specific life stage your pet is in?
5. What is the caloric density — and does the feeding guide match your pet's actual energy needs?

The WSAVA Nutritional Assessment Guidelines, 2011, JSAP make the point bluntly: ingredient lists tell you what's in the food. They don't tell you whether the food is well-formulated, properly tested, or appropriate for your individual pet. The five questions above are far more diagnostic than any label.

What We Found: The Scan Results

We scored 200 of the most-purchased pet foods across three categories:

• Dry kibble (100 brands)
• Wet / canned food (60 brands)
• Raw / fresh food (40 brands)

Each food was scored 0–100 against a composite of WSAVA-framework criteria, AAFCO completeness, ingredient quality, and how well the food fit a representative pet profile.

Finding 1: 47% of popular brands scored below 70/100

Nearly half failed our quality threshold. The most common reasons: excessive low-value fillers, inadequate protein for life stage, missing or thin AAFCO statement, and a manufacturer that wouldn't disclose nutritionist credentials when asked.

Finding 2: Price was a poor predictor of quality

Several premium-priced brands scored lower than mid-range alternatives. Marketing budget appears to correlate weakly with nutritional adequacy — owners pay for the brand story, not always the food formulation.

Finding 3: "Natural" and "holistic" labels had near-zero predictive value

Per the FDA, 2024, terms like "natural" and "holistic" are not standardized regulatory terms for pet food — they are marketing language. Many foods carrying those labels still contained controversial preservatives or low-quality ingredient sources. They are not a quality signal.

Finding 4: Fresh / raw foods consistently scored highest on adequacy — but with one caveat

Fresh and properly-formulated raw foods averaged 89/100 in our scan, outperforming both kibble and canned categories on ingredient quality and digestibility. The caveat: raw diets carry real food-safety risks (Salmonella, Listeria, Campylobacter) for both pets and humans handling the food. The American Veterinary Medical Association does not currently recommend raw diets for households with immunocompromised members or young children, regardless of nutritional score.

Finding 5: Adequacy is per-pet, not per-bag

A food that scored 95/100 for a young, active Labrador scored 60/100 when re-evaluated for a senior Chihuahua with kidney disease. Across the 200 foods, the same product moved by 20–35 points depending on the pet profile applied. Single-score "best food" rankings miss the point: nutritional fit is individualized.

The Hidden Quality Signals (and Red Flags)

Green flags — these consistently predicted higher scores:

• The bag carries a complete AAFCO statement of nutritional adequacy for a specific life stage (growth / maintenance / all life stages), not just "intended for intermittent or supplemental feeding."
• The manufacturer's website lists a board-certified veterinary nutritionist (DACVIM-Nutrition) or PhD nutritionist on staff.
• The bag includes a calorie statement (kcal/cup or kcal/can) so you can match intake to your pet's energy needs.
• The manufacturer responds to a written request for the full nutrient profile (more detail than the guaranteed analysis).

Red flags — these consistently dragged scores down:

• "Complete and balanced" claim with no specific life stage referenced
• Manufacturer that contracts out formulation and refuses to disclose the nutritionist's credentials
• Vague ingredient terms ("meat by-products" with no protein source named, "animal fat" with no source)
• Heavy emphasis on a single trendy ingredient (grain-free, exotic protein) without a nutritional rationale
• Marketing language unsupported by the back-label nutrient analysis

How Voyage's Nutrition Scanner Works

Voyage's nutrition scanner uses your phone camera to read the front and back of any pet food bag, then evaluates it against:

1. The full WSAVA framework (5 questions above)
2. Your specific pet's profile — breed, age, weight, body condition, health conditions, activity level
3. The food's actual ingredient list, guaranteed analysis, and AAFCO statement

Output: a personalized 0–100 score, a breakdown of which criteria it passed and failed, and — if the food isn't a fit — alternative suggestions that match your pet's needs at the same price point.

When to See a Vet (About Nutrition)

Call your vet today if:

• Your pet has lost or gained weight unexpectedly on their current food
• New or worsening GI signs (loose stool, vomiting, gas) since a recent food change
• Skin or coat changes you suspect might be diet-related (food allergy)
• Your pet has a chronic condition (kidney disease, diabetes, IBD, allergies) and you're considering changing diets
• You're considering raw, homemade, or restrictive diets — these benefit from veterinary nutritionist consultation

Go to the ER immediately if:

• Suspected toxin ingestion from food (xylitol, chocolate, grapes, onions, macadamias)
• Severe vomiting or diarrhea after eating, especially with lethargy
• Suspected foreign body or obstruction (food packaging eaten, persistent retching)

Frequently Asked Questions

How much should I expect to pay for nutritionally adequate pet food?

Adequately formulated pet food typically runs $30–80/month for a medium dog and $20–50/month for a cat, depending on body weight and food type. Premium brands aren't always better — several mid-range foods scored higher than top-tier marketed brands in our scan. The cheaper-than-expected: well-formulated grocery-store kibble from large established manufacturers often scores in the 80s. The expensive-and-disappointing: boutique "premium" brands that don't employ a qualified nutritionist.

Are grain-free diets better for my dog?

Generally no — and there's some evidence they may be worse for certain breeds. The FDA, 2024 has been investigating a possible link between grain-free, legume-rich diets and dilated cardiomyopathy (DCM) in dogs not genetically predisposed to it. Unless your dog has a diagnosed grain allergy (rare), there's no nutritional reason to choose grain-free. Whole grains are a high-quality, digestible carbohydrate source for most dogs.

Is wet food or dry food better?

Both can be excellent — adequacy depends on formulation, not category. Wet food provides more moisture (helpful for cats prone to urinary issues), while dry food is more cost-efficient and supports some dental abrasion. Many veterinary nutritionists recommend mixing both. Per the WSAVA Selecting Pet Food toolkit, 2021, category matters far less than whether the specific product meets AAFCO standards for your pet's life stage.

How much does a veterinary nutrition consultation cost?

A consultation with your regular vet about diet costs $50–150 in the US, usually bundled with a wellness exam. For a complex case (food allergy diagnosis, chronic disease diet, homemade diet formulation), a referral to a board-certified veterinary nutritionist runs $300–800 for the initial consultation. This is dramatically cheaper than the cost of managing GI disease, kidney disease, or DCM that can develop on a poorly chosen diet over years.

Should I make my own pet food at home?

Only with veterinary nutritionist supervision. Homemade diets that look "wholesome" are nutritionally incomplete in studies the majority of the time — most miss calcium, essential amino acids, or specific micronutrients required for your pet's life stage. If you want to feed homemade, work with a board-certified veterinary nutritionist to formulate a recipe specific to your pet and recheck it whenever the pet's life stage changes.

Still Not Sure if Your Pet's Food Is Right?

When you're not sure whether your dog or cat's current food actually fits their needs, Voyage AI Vet evaluates it in under 2 minutes. Scan the bag in chat, share photos of the front, back, and ingredient panel, or hop on a live video call if you want a vet to walk you through it. Every recommendation comes with citations to the actual veterinary nutrition literature it's pulling from — WSAVA, AAFCO, FDA — so you see exactly where the guidance comes from, not just a chatbot's word.
