Chewy Pet Category Analytics: What the 10-K Shows and What to Track

The short answer

Chewy's own filings establish that it is a subscription-dominated US pet retailer whose fastest-growing reported categories are pet health and hardgoods, and whose Autoship program now covers the large majority of net sales. Its fiscal 2025 Form 10-K (fiscal year ended February 1, 2026) reports net sales of $12.6 billion, up 6.2% year over year, with Autoship customer sales of $10.5 billion equal to 83.3% of net sales, up from 79.2% the prior year. Those figures come from Chewy's fiscal 2025 annual report on SEC EDGAR and investor.chewy.com.

What the filings do not establish is equally important: item-level sales, brand share of category, search placement, sponsored-ad spend by vendor, or stock status. None of those are disclosed at SKU resolution, which is exactly why brands track the storefront directly rather than relying on investor materials alone.

What the fiscal 2025 10-K actually reports

Active customers reached 21.3 million (+4.0%) and net sales per active customer $591 (+2.2%). Gross margin rose 60 basis points to 29.8%, which the company attributes to sponsored ads growth and consumables margin — not to pharmacy, whose specific profitability is not broken out anywhere in public reporting.

Autoship economics: read the definition before quoting the number

The headline figure is easy to misquote. Chewy defines Autoship customer sales as all purchases — inside the subscription and outside it — made by customers who used Autoship at some point in the preceding 364 days. The 83.3% figure is therefore a customer-cohort share of revenue, not the share of orders placed on automatic renewal. Both readings matter for brands, but they answer different questions:

• Cohort share (83.3%) tells you how much of Chewy's revenue comes from committed households — useful for judging how much weight a Chewy observation carries.
• Subscription-order share would tell you how often a given SKU sells on a recurring schedule — that is not disclosed and must be inferred from storefront behavior.
• A January 2025 Packaged Facts survey cited in the 10-K found 49% of online pet-product buyers had used an autoship-style program in the prior 12 months — so subscription behavior is category-wide, not a Chewy artifact.

Practically, autoship concentration means price and promotion observations on Chewy behave differently than on open marketplaces: a household that locks a staple into autoship may never see a promotion targeted at first-time buyers, and vice versa. Segmenting observed promotions by new-versus-repeat context is one of the more sensible early tests when standing up monitoring here.

Pharmacy and Chewy Health: strong claims, partial disclosure

Chewy states in the 10-K that it operates “the #1 pet pharmacy in America” — a self-characterization, though the surrounding infrastructure is concrete: roughly 20,000 veterinary practices enrolled in PracticeHub as of February 1, 2026, which the company estimates at about half of US vet clinics, plus 18 Chewy Vet Care locations after opening eight in 2024 and ten more in 2025. The same filing flags the dependency plainly: prescription sales rely on veterinarians authorizing scripts, the business is subject to extensive state and federal pharmacy regulation, and vet resistance could reduce sales. For analytics purposes, pharmacy is best treated as a high-value, regulatorily mediated category where listing-level signals are observable but conversion is not.

Private labels compete on the same shelf

Chewy partners with approximately 4,000 third-party brands while offering roughly 190,000 products — and its own private brands sit inside those results: Frisco (hardgoods, 2016), American Journey and Tylee's (consumables), Vibeful (wellness, 2022), and Get Real, a fresh, minimally processed dog food line launched in 2025 as a Chewy exclusive. Any share-of-shelf measurement that ignores house brands will systematically misstate the competitive set, particularly in consumables where private label is strongest.

Pet categories worth tracking

What pet brands should track on Chewy

• Share of shelf in search: rank position for category and branded keywords, keeping sponsored and organic placements distinct — Chewy's sponsored ads offering has expanded since its 2022 beta and now influences gross margin.
• Out-of-stocks: distinguish in-stock, out-of-stock, unserved, and unlisted states; an interrupted autoship staple is a substitution event, so availability gaps carry more weight here than on browse-led marketplaces.
• Review velocity: new reviews per SKU per week as a directional proxy for shipment momentum — a proxy only, never a sales estimate.
• Price and promotion parity against other US pet channels, including whether Chewy-exclusive bundles or sizes blunt direct comparison.
• Private-label adjacency: where Frisco, American Journey, Vibeful, or Get Real appear relative to your SKUs in search and category pages.

Two scope notes before you build the panel

First, geography: Chewy launched Chewy Canada in 2023, and its 10-K cites an October 2025 Packaged Facts estimate that about 62% of Canadian households have pets. If your category review covers North America rather than the US alone, decide explicitly whether chewy.com/ca is in scope, because assortment and pricing differ across the two sites. Second, fulfillment: Chewy ships from its own fulfillment centers and states it can reach over 80% of the US population overnight and nearly 100% in two days. Availability observed on the site therefore reflects Chewy-owned inventory, not marketplace sellers, so out-of-stock readings are cleaner but also mean there is no third-party seller layer to analyze separately.

Third, cadence: because the customer base is subscription-weighted and the category has low seasonality — both noted by Chewy as drivers of its network efficiency — most pricing moves are competitive responses rather than seasonal resets. That argues for steady daily observation over event-driven snapshots: the interesting signal is a competitor holding a new price for weeks, not a one-day promo.

What this data cannot tell you

None of these observations establishes unit sales, inventory quantities, or causal campaign lift. They establish what shoppers were shown, at what price, in what position, and whether they could buy it — which is the evidence base a brand actually makes decisions against. Three specific limits deserve stating:

• No conversion data. A high rank with strong review velocity still does not reveal whether shoppers bought.
• No margin data. Observed retail prices say nothing about trade spend, co-op funding, or the effective wholesale price behind a promotion.
• No subscriber visibility. Which offers reach autoship households versus new customers is not observable from a single session profile.

Bottom line

Chewy's filings justify treating it as the center of gravity for US pet-care ecommerce intelligence: a $12.6 billion revenue base, 83.3% of it flowing through autoship-affiliated households, health products growing double digits, and private labels pushing into fresh food. The storefront-level questions — who ranks, at what price, in stock or not — remain unanswered by filings and answerable only through systematic collection.
