Largest Veterinary Chains in the US: Mars Owns 2,081 US Hospitals, Top 10 Hold ~14%.

Orbital counts 54,297 active US veterinary care locations as of June 2026. The AVMA reports roughly 32,000 US practice entities. Both numbers are right; they answer different questions. Orbital counts every location (mobile pop-up addresses, in-store retail clinics, satellite ER hospitals, house-call businesses) as a separate site. AVMA counts each practice entity once. Vendors prospecting by sales territory want the location count. Vendors prospecting by buying entity want the practice count.

Mars Petcare runs 2,081 US veterinary hospitals across three brands: VCA Animal Hospitals at 982 sites, Banfield Pet Hospital at 999 sites (most of which sit inside PetSmart stores), and BluePearl Specialty and Emergency at 100 sites. That total reconciles within about 10 percent of Mars Veterinary Health's own corporate communications, which cite roughly 2,000 US hospitals. No other operator is close.

AVMA's annual census is entity-grain and self-reported. Orbital's count is location-grain, signal-driven, and refreshed monthly. The two diverge because of mobile-clinic networks, in-store retail clinics at Petco and PetSmart, satellite emergency hospitals, and house-call businesses, all of which AVMA folds into a single practice entity and Orbital counts as separate operating sites. Neither approach is wrong. Pick the one that matches your sales motion.

NVA (National Veterinary Associates), backed by JAB Holding, runs roughly 1,100 US clinics. VetCor runs roughly 700. Thrive Pet Healthcare (TSG Consumer Partners) runs 305. Ethos Veterinary Health runs roughly 145 specialty hospitals. VEG (Veterinary Emergency Group) is at 114, also under JAB. Lap of Love runs 101 in-home hospice businesses. Combined, the PE-rolled networks below Mars own roughly 5 percent of US locations and most of the dollar growth in the segment over the last decade.

They are a different business entirely. VIP Petcare runs 2,105 pop-up community clinics inside Tractor Supply, Pet Supermarket, and similar retail partners. Each pop-up uses the host retailer's address. There is no freestanding hospital. ShotVet runs 372 of the same model. Petco operates 1,633 in-store Vetco clinics, a mix of full-service Vetco Total Care hospitals and walk-in vaccination clinics. Treat these as a distinct ICP: they buy vaccines and pop-up logistics, not exam-room equipment.

Yes. The dataset is segmentable by state, metro, model (freestanding hospital, mobile, in-store, urgent care, emergency, hospice), parent group (Mars, PE-rollup, true independent), and chain affiliation. The sample includes 100 records pulled to your filter; if you want California-only Mars VCA hospitals or Texas-only true independents, that is what arrives.

If you only sell to one or two corporate accounts (Mars's procurement team or NVA's central supply group), you do not need 54,297 records. You need a named contact at two companies. If your product is for pet owners (a consumer app, a direct-to-consumer pet food), this is operator-side data, wrong audience. If you need clinical or DEA-regulated practice data (Schedule II inventory, board complaints), state veterinary boards and the DEA are your sources, not us.

Orbital's chain resolver currently keeps NVA's acquired-brand identities (Carolina Veterinary Specialists, Mission Veterinary Partners pre-merger entities, and so on) separate from the NVA parent, so the NVA chain entity surfaces only one or two US locations in our raw data. Public PE coverage and NVA's own corporate communications cite roughly 1,100 US clinics, and that number is consistent across sources. Re-rolling the acquired brands under their PE parent is on our engineering backlog. We surface the public number on this page because it is closer to ground truth than our current chain entity.
