Key takeaway
The dog food category remains dominated by the WSAVA-compliant "Big Three" — Purina Pro Plan, Royal Canin, and Hills Science Diet — across every AI model. Claude has emerged as the most prescriptive recommender, treating dog food as a science question rather than a brand question. Modern fresh/DTC brands like The Farmers Dog have meaningful Gemini visibility but remain invisible to ChatGPT, Claude, and Perplexity. Mid-tier specialty brands (Fromm, Open Farm, Victor, Acana) have strong single-model presence but zero cross-model authority.

What This Means
- ChatGPT is the most commerce-formatted with explicit prices, star ratings, and review counts — and it's the only model surfacing Fromm, Pure Balance, and Merrick.
- Claude is the most opinionated and pro-veterinary, explicitly calling out boutique brands (Farmers Dog, Ollie, Sundays, Raised Right) as "marketing not science" and uniquely surfacing Eukanuba, Acana, Wellness Core/Complete Health, and Kirkland Signature as Costco value play.
- Gemini introduces lifestyle/aesthetic brands (Open Farm Ancient Grains, Victor Classic, 4Health) and prominently features The Farmers Dog as a top-3 pick.
- Perplexity is the most consolidated and uniquely surfaces Natures Recipe and the Blue Buffalo Jolly Joints variant.
