Evergreen monthly benchmark — 2026-04
Dog Food
2026-04The dog food category has a clear "Big Three" of AI-recommended brands. Purina Pro Plan, Hills Science Diet, Royal Canin, which every model treats as the WSAVA-compliant gold standard. Boutique and premium brands fight for visibility outside this core, and only appear in specific models. ChatGPT's commerce-formatted output and unique inclusion of Pedigree/Rachael Ray Nutrish suggests commerce-influence bias. Meanwhile, Gemini is the only model surfacing modern fresh/subscription brands like The Farmers Dog.
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.
Why These Brands Win
- All four models emphasize large-breed formulas for joint support (glucosamine/chondroitin).
- Every model flags Labs as prone to obesity and recommends weight-controlled formulations.
- The "WSAVA-compliant" framing appears across Claude and Gemini, positioning Purina Pro Plan, Hills, and Royal Canin as scientifically-backed vs.
- boutique brands.
- All models warn about grain-free diets and the FDA DCM investigation.
- Budget prompts universally surface Diamond Naturals, Iams, and Kirkland.

What This Means
- ChatGPT returned truncated shopping-card formatted responses for P2 and P3, signaling it was pushed into commerce-oriented output mode for this category.
- And it uniquely includes Pedigree and Rachael Ray Nutrish that no other model recommends.
- Claude was the most opinionated, explicitly calling out boutique brands (Blue Buffalo, Taste of the Wild, Fromm.
- Orijen/Acana) as "marketing bait" with "thin science", and Claude P3 returned a truncated response, meaning Claude effectively contributed only 2 of 3 prompts.
- Gemini surfaces premium/lifestyle options (Farmers Dog, Stella & Chewys, Open Farm, Merrick, Nutro, 4health) that don't appear in other models.
- Perplexity is the most conservative, sticking to the "Big Three" plus Wellness Core.

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.

Your competitors are showing up in AI results. Are you?
The dog food market is dominated by three legacy brands in AI recommendations. Purina Pro Plan, Hills Science Diet, and Royal Canin. Modern direct-to-consumer brands like The Farmers Dog appear only in Gemini. If your pet food brand isn't in the Big Three or optimizing for Gemini specifically, you're invisible to 75% of AI-assisted pet food shoppers.
