Which Veterinary Hospital Groups Are Owned by Private Equity?

Two kinds of buyer keep showing up at the top of this market.

A strategic owner runs hospitals inside its own operating business — Mars, Incorporated is the clearest example in the table below, with Banfield, which says it joined the Mars family of businesses in 2007, and VCA, which Mars acquired in 2017.

A private equity backer is an investment firm sitting above the operating group rather than running hospitals itself.

The clearest public records name the structure directly: the FTC's 2022 orders identify JAB Consumer Partners as the parent of National Veterinary Associates and Compassion-First Pet Hospitals, and Thrive Pet Healthcare's March 2025 financing announcement names TSG Consumer Partners as its equity sponsor.

What a private equity owner means for a practice — pay, staffing, how decisions travel — is its own question, and our private equity in vet med explainer covers it.

This page answers the narrower one: who owns whom, as of when.

Every owner below comes from the group's own site, an FTC order, or — where neither names a backer — a research pass that found nothing verifiable.

Counts are the groups' self-reported figures as read on October 22, 2026, unless a date is shown.

Read the fine print before quoting any of these.

NVA's 1,325 is a locator count of all location types, not a hospital count.

VEG's own page is inconsistent — one line says over 130 hospitals, another says more than 140 — so this table uses 130+.

The Mars Veterinary Health counts are worldwide, not U.S.-only — nearly 70,000 associates across 3,000 veterinary clinics worldwide, per the site's own description — and other Mars pages have carried different counts, so treat every figure here as a dated self-description.

Where an owner cell says Not disclosed — Mission Pet Health, Southern Veterinary Partners, PetVet and AmeriVet — no owner or backer for that group was verified from a company, SEC or FTC source during this research.

United Veterinary Care's backer was not verified either: the FTC record names it as the divestiture buyer in the JAB/SAGE order and nothing more about its ownership.

We have left those cells marked rather than filling them with a name circulating in the industry without a source.

VEG is marked separately because the sources cited on this page simply do not state an owner for it.

Acquisitions are where group ownership becomes public record: each of the three orders below names a parent, a price and — where competition was the concern — the divestitures required to close.

Together they explain most of the structure in the table above:

• 2017 — Mars/VCA. The FTC required Mars to divest 12 specialty and emergency clinics as a condition of its $9.1 billion acquisition of VCA Inc. The same order required financial incentives for key employees at divested clinics to stay, and barred Mars for a year from contracting with specialists affiliated with a divested clinic.
• June 2022 — JAB/SAGE. The FTC required JAB Consumer Partners to divest clinics in California and Texas as a condition of its $1.1 billion acquisition of SAGE Veterinary Partners, and to get the FTC's prior approval before acquiring a specialty or emergency veterinary clinic within 25 miles of a JAB-owned clinic in those states. The divestiture buyer was United Veterinary Care, LLC — which the same order also requires to obtain the FTC's prior approval.
• October 2022 — JAB/Ethos. The FTC finalized its order on JAB's $1.65 billion acquisition of the parent company of Ethos, requiring divestitures in Richmond, Virginia; Denver; San Francisco; and the Washington, D.C. area.

Not every ownership event is a sale to a new backer.

In March 2025, Thrive Pet Healthcare announced new financing supported by 100% of its existing lenders and its equity sponsor, TSG Consumer Partners — the same announcement in which it described itself as owner-operator of over 360 veterinary hospitals.

A refinancing changes no logo, but it is a reminder that the owner of record and the brand on the door are different questions.

Start from the assumption that the brand proves little.

Some groups in the table above are themselves consumer brands — Banfield, VCA, VEG — while others are holding-platform names a hospital's sign may not carry.

Treat the logo as a starting point, not the answer.

The check we would run, in order:

• Read the group's own pages. The groups that name an owner do it themselves: Banfield's about page says it joined the Mars family of businesses in 2007, and Thrive's March 2025 financing announcement names TSG Consumer Partners.
• Search the FTC's press room for the big deals. The 2017 Mars/VCA order and the two 2022 JAB orders name the parents — and, where a deal was conditioned, the divestiture buyers. United Veterinary Care entered the public record exactly that way.
• Look at the entity on your paperwork. Offer letters and pay stubs name the legal employer — the structure that actually employs you — rather than the brand.
• Ask. A candidate can ask who owns the practice and how decisions are made; an owner fielding a buyer's approach can ask the same questions back and put the answers in the deal documents.

And date whatever you find.

Company sites change their own counts without notice — VEG's page currently carries two different hospital totals — and an owner named in a 2022 FTC order may not be the owner by the time you read this.

The table above is a snapshot of October 22, 2026, which is exactly how a page like this should be read.

For the practice's legal frame, ownership changes less than you might expect.

Who may hold equity in a veterinary practice is state law: a VeterinaryHires statute-by-statute read of all 51 jurisdictions (50 states plus DC) found nine restrict who may hold equity in a veterinary practice, four permit lay ownership but bar lay control of clinical judgment, and fourteen permit it behind a facility permit with a named responsible veterinarian.

Any buyer — group or individual — has to work within those rules state by state; our guide to practice ownership, state by state covers the picture.

For your day-to-day employment, the useful questions are the ordinary ones: which entity is your legal employer, how pay is set and raised, and what the covenants in your agreement actually restrict.

Those belong to their own guides — start from the veterinarian salary guide or the vet tech salary guide for pay, and from the non-compete series for post-employment restrictions.

When hospitals change hands inside a group, deal terms can reach staff directly.

The FTC's Mars/VCA order required financial incentives for key employees at divested clinics to stay, and barred Mars for a year from contracting with specialists affiliated with a divested clinic — so if your hospital is ever on the divested side of a deal, read the order itself, not just the buyer's announcement.

If you run an independent practice and the groups on this page are your competition for hires, the productive question is how you compare on what candidates actually weigh.

Our corporate vs private practice guide lays out the trade-offs from both sides of that comparison.
