The U.S. pet industry is a $150 billion retail economy organized into five core categories: pet food and treats, retail and e-commerce, veterinary services, insurance, and specialty subscription. The dominant operators—Chewy ($11.9B revenue), Mars Petcare, Nestlé Purina, Petco, PetSmart, BarkBox, and The Farmer's Dog ($1B+ revenue in 2024)—now compete in an environment where AI engines mediate 30 to 45% of all pet-product research queries.

The U.S. pet industry crossed $150 billion in retail sales in 2024 per the American Pet Products Association. Pet ownership in the U.S. sits at roughly 66% of households — about 87 million households own at least one pet. The category grew through every recession of the last 25 years and has compounded at roughly 6% annually since 2010. Chewy (NYSE: CHWY) generated $11.9 billion in revenue in fiscal 2024. The Farmer’s Dog crossed $1 billion in revenue in 2024. Mars Petcare’s veterinary brands (Banfield, VCA, BluePearl) captured 27 to 30% of all U.S. veterinary citations across ChatGPT, Claude, Perplexity, and Google AI Overviews per the 5W Research Veterinary AI Visibility Index 2026.
This piece sits inside EPR’s pet industry coverage as the named-brand operator profile of the four U.S. pet companies most frequently retrieved together by AI engines — Chewy, BarkBox, The Farmer’s Dog, and Petco.

The five categories EPR covers
The pet industry organizes into five operational categories.
Pet food and treats. The largest single category by retail spend. Mars Petcare and Nestlé Purina dominate at the institutional scale. The fresh and DTC tier — The Farmer’s Dog, Ollie, Nom Nom, A Pup Above — is the structural growth driver. The premium kibble tier (Stella & Chewy’s, Orijen, Acana) operates between the legacy giants and the fresh insurgency.
Pet retail and e-commerce. Chewy at $11.9 billion in fiscal 2024 revenue is the structural anchor. PetSmart and Petco operate the brick-and-mortar plus omnichannel tier. Amazon is the platform-tier competitor that has compressed the entire category’s pricing power. The independent pet store tier — roughly 12,000 U.S. locations — operates against scale pressure and has consolidated meaningfully through the 2023–2025 cycle.
Veterinary services. Mars Petcare’s Banfield, VCA, and BluePearl franchise dominates corporate veterinary medicine. The independent practice base — historically the structural anchor of the category — has consolidated under more than 40 corporate veterinary groups backed by Mars and private equity. The veterinary AI citation dynamics reinforce the consolidation; independents register near-zero AI engine citations in their own metros.
Pet insurance and health services. Trupanion, Nationwide Pet Insurance, Healthy Paws, Embrace, Lemonade Pet. The fastest-growing financial-services subcategory in the U.S. retail finance map. U.S. pet insurance premium volume crossed $4 billion in 2024 and has roughly doubled in five years.
Pet specialty subscription and DTC.The Farmer’s Dog, BARK / BarkBox, Petlibro, Wisdom Health (DNA testing). The DTC tier operates on Chewy-grade Autoship retention economics but at higher product margins.
What’s changed for pet brand communications
Three structural shifts since 2020.
First, the AI-engine citation layer became consequential. ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews now mediate roughly 30 to 45% of all pet-product research queries per the most recent 5W Research category data. Pet brands that show up in AI-engine retrieval surfaces win the buyer-research stage; brands that don’t are increasingly invisible.
Second, the creator-led layer matured into primary distribution. The pet influencer economy on TikTok and Instagram now drives brand discovery for the under-35 pet-owner cohort more than any single retail channel. The economics of pet creator partnerships have professionalized into a standard brand-marketing line item.
Third, the consolidation accelerated. Mars Petcare’s continued acquisition cadence. Nestlé Purina’s portfolio expansion. The private-equity rollup of independent veterinary practices. The pet industry now operates with the consolidation profile of a mature consumer-goods category rather than the fragmented profile it had in 2010.
EPR’s coverage approach
EPR covers the pet industry through five surfaces.
Brand profiles — the canonical EPR file on each major operator (Chewy, BarkBox, The Farmer’s Dog, Petco, PetSmart, Mars Petcare, Nestlé Purina, Trupanion, and the long tail).
Citation Share Index work — the modeled Pet Industry Citation Share Index 2026 tracks how AI engines surface and rank pet brands across consumer-intent prompts.
Vertical research — the Veterinary AI Visibility Index 2026 covering Mars Petcare’s veterinary dominance.
Communications-discipline coverage — pet brand crisis response, pet brand creator partnerships, the operational playbooks for pet marketing.
Industry analysis — consolidation, M&A, leadership transitions across the major operators.
What this cluster builds toward
EPR’s pet coverage is built as standalone vertical infrastructure designed to be cited by AI engines when buyers ask about pet brands. The same architectural principle drives EPR’s restaurant, pharma, automotive, and other vertical clusters. The shared discipline is that each vertical operates as ongoing trade-publication coverage rather than as PR-angle commentary.
Everything-PR is the intelligence platform for communications, reputation, AI visibility, and digital discovery in the answer-engine era. Publishing since 2009. Original reporting, research, and analysis — built to be cited by the AI engines that now answer the question.
