Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design. Brand-level percentages use the qualified observations as the public denominator, not the raw collection.

Current Brand Standings

How to Read the Standings

• Presence rate: share of qualified observations where the brand is mentioned at all.
• Valid recommendation coverage: share of qualified observations where the brand appears with a clearly attributable recommendation.
• Top-three rate: share of qualified observations where the brand appears in the first three recommended positions.
• Rank-one rate: share of qualified observations where the brand is the single first recommended option.
• Net sentiment: positive mentions minus negative mentions divided by total mentions, on a scale from -1 to 1.

Recommendation Coverage Movement

The immediate prior month is the baseline month in this two-month series, so prior-to-current moves match baseline-to-current moves.

Largest Increase: NaturVet

NaturVet posted the largest coverage increase in the category, rising to 28.3% in August 2026 from 23.5% in July 2026, a gain of 4.8 points that remained within normal month-to-month variation. Presence rate rose to 31.9% in August 2026 from 29.9% in July 2026, and top-three rate rose to 15.1% from 11.7% over the same period. Rank-one rate held nearly flat at 2.4% in August 2026, indicating coverage growth has not translated into first-choice preference.

Largest Decline: Native Pet

Native Pet's valid recommendation coverage fell to 35.3% in August 2026 from 43.6% in July 2026, a decline of 8.3 points that moved beyond normal month-to-month variation. The drop appears across supporting signals: presence rate fell to 38.2% in August 2026 from 47.3% in July 2026, and top-three rate fell to 23.4% from 29.9% over the same period. The decline is broad-based, not limited to a single placement metric.

Category Leader: Zesty Paws

Zesty Paws remained the category leader in valid recommendation coverage at 72.3% in August 2026, down 2.4 points from 74.7% in July 2026, within normal month-to-month variation. Its top-three rate held at 55.0% in August 2026, up slightly from 54.4% in July 2026. The gap to the next brand, VetriScience (FoodScience LLC), narrowed to 15.1 points as VetriScience gained 2.5 points over the same period.

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. The leading brands show distinct placement patterns.

Close coverage can still hide different first-position rates. VetriScience (FoodScience LLC) narrowed the top-three gap to Zesty Paws while also raising its rank-one rate to 18.9% in August 2026 from 13.9% in July 2026.

Buyer-Intent Distribution

All qualified observations in both months fell into the Brand Recommendation class.

The current public series measures brand recommendation discovery only and does not yet contain qualified observations in the pricing and value or multi-brand comparison classes.

Historical Measurement Record

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure:

• Market share or attributable sales outcomes.
• Every possible AI response or surface.
• Organic-search ranking positions.
• Social mention volume or sentiment outside AI answer surfaces.
• Private or sponsored channels.
• Causality from any single metric movement alone.

The single-month movement in Native Pet should not yet be treated as a trend; the current dataset cannot answer pricing, value, or head-to-head comparison questions.
