Evergreen monthly benchmark — May 20
Dog Food
May 20Rank Trend
How top brands moved week over week. Rank 1 is the top position.
For a Labrador owner, AI recommendations consolidate around three brands - Purina Pro Plan. Hills Science Diet, and Royal Canin - in every single response from every model. This is the most locked universal-tier consensus we have observed. The cross-model consensus is also that these three are recommended specifically because they meet the full WSAVA criteria, which most boutique brands fail by design. The brand-recommendation moat is built on veterinary infrastructure investment (full-time nutritionists, owned manufacturing, feeding trials) that takes years to replicate.
Top Brands by AI Mention Frequency
Mention frequency counts how many times a brand appeared across all AI responses. This differs from top-pick rank, which reflects each model’s #1 choice.
Opportunity for Brands
- Mid-price US DTC fresh-delivery brands (The Farmers Dog, Ollie, Spot & Tango.
- Nom Nom) are dismissed or downranked despite massive marketing spend - this is a category-level audit insight.
- Single-protein/limited-ingredient brands beyond Royal Canin and The Honest Kitchen (Zignature, Natural Balance, Canidae LID) do not surface.
- Raw and freeze-dried brands (Stella & Chewys, Primal, Steve Real Food) are nearly absent or explicitly warned against.
- Costco-channel exclusive brands beyond Kirkland are missing.
- Lower-priced grocery channel brands (Pedigree, Beneful) are absent despite being category volume leaders.

|---|---|---|---|
| chatgpt | Purina Pro Plan | Hills Science Diet | Royal Canin |

What This Means
- ChatGPT defaults to the broadest brand surface and surfaces Eukanuba and Open Farm.
- Claude is the most opinionated and the most willing to actively dismiss boutique brands by name (Farmers Dog, Ollie.
- The Honest Kitchen, grain-free anything, raw diets) and is the only model to surface Kirkland Signature as a legitimate value pick.
- Gemini converged tightest on the Royal Canin Labrador-specific formula at #1 (3 of 3 prompts) And is the only model to recommend Purina ONE as a separate value tier.
- Perplexity is the only model to recommend The Honest Kitchen as a top human-grade pick And the only one to surface Victor and Diamond Naturals as value brands.
- The universal cross-model signal across all four is active warning against grain-free diets pending FDA DCM investigation - this is now consistent enough that any brand whose differentiation depends on grain-free positioning faces structural AI headwind.
Why These Brands Win
- WSAVA criteria compliance (board-certified veterinary nutritionist on staff, feeding trials, own manufacturing), AAFCO adult maintenance statement, large-breed-specific formulation.
- Glucosamine/chondroitin for joints, controlled calorie density for weight management, and named meat as first ingredient are the recurring traits.
- Hero SKUs: Purina Pro Plan Large Breed Adult, Royal Canin Labrador Retriever Adult, Hills Science Diet Adult Large Breed.

How we measure this
Each benchmark runs the same standardized prompts across multiple leading AI systems, including ChatGPT, Claude, Gemini, and Perplexity. We use consistent, category-specific questions designed to surface genuine product recommendations — not sponsored results.
Responses are parsed to extract brand mentions, rank position, and frequency. We then analyze cross-model agreement, identify which brands consistently appear in top positions, and flag where AI outputs diverge from marketplace trends.
Evergreen categories are benchmarked monthly. Results reflect organic AI behavior at the time of testing. Read the full methodology
