What Does a Veterinarian Do?

Start with the boundary, because it defines everything else about how a practice is staffed.

The acts that define veterinary medicine — diagnosis, prescribing and surgery — sit with the licensed veterinarian.

AVMA policy says a veterinary technician works under the direction, supervision and responsibility of veterinarians, and that a technician's duties "shall not include diagnosing, prescribing, or performing surgery except where explicitly permitted by regulation."

The exact shape of the boundary lives in each state's practice act — verify with your state board.

That is also why supervision exists as a system: clinical work is delegated, and the veterinarian remains responsible for it.

If you are staffing a practice, the practical question is never "who can do this task" in isolation — it is what may be delegated, to whom, and at what level of supervision.

The delegation side of that is covered from the team's perspective in the supervision guide.

Stripped to its core, a veterinarian's job description is the acts above — diagnosis, prescribing and surgery — wrapped in the daily work of examination, client communication and case management.

The responsibilities that make up the role, in one list:

• Wellness examinations, vaccination and preventive care — the routine backbone of general practice.
• Diagnosing and working up sick or injured patients — receiving the case, forming the diagnosis and the prognosis.
• Performing surgery — in companion-animal practice, the routine end of it runs from spays and neuters to dentistry, which AVMA policy counts as part of the practice of veterinary medicine, and mass removals.
• Prescribing medication and treatment — one of the acts AVMA policy keeps off the technician's task list, except where a regulation explicitly permits otherwise.
• Client communication — BLS lists communication and compassion among the important qualities for veterinarians; the conversations run from a diagnosis and the treatment options to end-of-life decisions.
• Euthanasia — BLS lists it among the emotionally stressful parts of the job, alongside supporting anxious owners.

That list is the career description in brief; how the work is weighted changes with the practice type and setting covered below.

If you are an employer writing one of these, start from the veterinarian job description template rather than a blank page.

In companion-animal general practice, the day mixes scheduled wellness visits, sick-patient work-ups and surgery.

Threaded through it is the communication half of the job — BLS's important-qualities list for veterinarians runs communication, compassion, decision-making, manual dexterity and problem-solving.

There is also a management layer: technicians work under the veterinarian's direction, supervision and responsibility, and handling controlled substances runs through the DEA registration system.

Species is the first fork in the job.

Small animal — companion-animal practice, dogs and cats predominantly — is where most of the profession sits: BLS says most veterinarians work in private clinics and hospitals, and about three in four veterinarians in practice work in companion-animal care (AVMA, 2023).

Mixed practice covers both companion and farm species, and the farm-species side is ambulatory: BLS describes the veterinarians who treat horses or food animals as travelling between their offices and farms and ranches, working outdoors in all kinds of weather and sometimes performing surgery in remote locations.

Large animal and food animal work centres on the herd rather than the appointment — BLS describes food-animal veterinarians as visiting farms and ranches to treat ill and injured animals, test for and vaccinate against disease, and advise owners or managers on feeding, housing and general health practices.

Equine practice is its own world — largely on the road, by BLS's description of the veterinarians who treat horses — and BLS notes that work on farms and ranches can be physically demanding.

Beyond private practice, the track list runs through shelter medicine, laboratory animal medicine, zoo and exotics, government and public health, academia and industry — AVMA counts active diplomates in laboratory animal medicine (ACLAM), zoological medicine (ACZM) and shelter medicine (ABVP), and in the public sector its largest employer of veterinarians is colleges and universities.

The three main species tracks — what each involves, where the jobs are, and what sourced data does and doesn't show — are compared in full on the small animal vs mixed vs large animal page.

Within small-animal work, the practice model is the career-shaping fork — and for the newest class it was already partly settled at graduation: 28.2% of 2026 new veterinarians had accepted advanced education (internships, residencies, graduate study) by the time of AVMA's Senior Survey, taken about four weeks before graduation.

General practice runs on an appointment book and continuity of care — you see the same patients over years, and the caseload spans wellness through chronic disease and routine surgery.

Emergency and critical care is triage-driven and shift-based.

BLS notes that some veterinarians work nights or weekends and may have to respond to emergencies outside scheduled hours, and the hospitals that train ACVECC residents must, under the college's standards, be open 24 hours a day, every day of the year.

The medicine is acute and unscheduled — see what an emergency veterinarian does for the credentials, pace and pay specific to that track.

Specialty referral runs through a rotating internship and a residency to board certification — AVMA recognises 22 specialty organisations comprising 48 distinct specialties.

ACVS's sequence, for example, is a 12-month rotating internship (or equivalent) followed by a residency of at least three years; ACVECC's residency minimum is 36 months.

AVMA's 2026 Senior Survey averaged starting pay at $59,436 for internships and $54,988 for residencies, against $131,784 for graduates entering full-time employment.

There is also relief work: covering shifts across practices on a contract basis rather than holding a staff position.

It is structured — and taxed — differently from employment; the relief-work page covers classification and what a rate has to absorb.

No practical difference.

BLS states the requirement as a DVM or VMD from an accredited veterinary college, plus a state licence — one requirement, two degree names.

The federal government reads them the same way: for its veterinarian roles, FSIS lists "Veterinary Medical Doctor (VMD)" as the equivalent degree to the Doctor of Veterinary Medicine from a school accredited by the AVMA Council on Education.

Whichever abbreviation a school uses, the licence path is the same: the NAVLE — administered by the ICVA since 2000 and a requirement for licensure in all U.S. and Canadian licensing jurisdictions — and then the state licence.

If you see both abbreviations in a practice's staff list, both names mark the same qualification.

Three gates, and the first is the long one.

Foreign-trained veterinarians certify their education before the exam: AVMA's ECFVG certificate is accepted by all U.S. state veterinary regulatory boards — and the federal government — as meeting, in part or in full, the educational prerequisite for licensure, and AAVSB's PAVE serves graduates of international, non-accredited programs, with acceptance to be confirmed per jurisdiction.

The full sequence — prerequisites, VMCAS, exact NAVLE structure, and how state licensing diverges — is covered step by step in how to become a veterinarian.

Beyond licensure, an optional rotating internship — a one-year position, or equivalent experience, on the route the specialty colleges set — and a residency of several years lead to board certification in a specialty.

Neither is required to practise, and for those who take one, AVMA strongly recommends choosing an internship with a clear path to career advancement.

The Bureau of Labor Statistics puts the median at $130,100 a year (May 2025), with the middle half of veterinarians earning between $101,460 and $166,120.

The lowest 10% earned less than $73,920; the highest 10% more than $215,700.

The headline hides several axes.

BLS's own median by industry ranged from $115,210 in government to $131,760 in social advocacy organizations in May 2025, and its state-by-state medians differ again — the state series is on the highest-paying states page.

The third axis is the contract itself: how compensation is structured — flat salary, production-based, or a hybrid — decides what a caseload actually pays, and the details inside a formula matter as much as the headline number.

ProSal and production pay takes the formula apart — base, percentage, and the negative-accrual clause inside it.

And the other half of the economic picture is debt: AVMA puts the average debt-to-income ratio for 2026 graduates entering full-time employment at 1.5:1, with 18.1% of new graduates at 2.5:1 or higher.

The debt-to-income page carries the full figures.
