Veterinarians study animal biology, medicine, and surgery in a four-year professional program

A veterinary degree requires a Doctor of Veterinary Medicine (DVM) or Doctor of Veterinary Science (DVS) — a four-year professional program that comes after completing prerequisite coursework in college. The curriculum covers anatomy, physiology, pharmacology, and pathology across multiple animal species, alongside hands-on clinical training with real patients. By graduation, a vet has studied how to diagnose disease, perform surgery, prescribe medication, and manage the health of animals ranging from household pets to livestock to exotic species.

The path to becoming a veterinarian is longer and more structured than many other professions. You cannot major in veterinary medicine as an undergraduate; instead, you complete a bachelor's degree in any field while taking specific prerequisite courses — typically biology, chemistry, organic chemistry, biochemistry, physics, and mathematics. After that, you explore to veterinary school, where the actual DVM program begins. Most schools require a minimum GPA and scores on the Graduate Record Examination (GRE) or the Veterinary Medical College Admission Test (VMCAT).

Key Takeaways

  • Veterinary school is a four-year professional program that comes after completing a bachelor's degree and prerequisite science courses.
  • The curriculum includes anatomy, physiology, pharmacology, pathology, and clinical practice across different animal species.
  • Veterinarians must pass the North American Veterinary Licensing Examination (NAVLE) to practice, and most states require additional state-specific exams.
  • Specialization in areas like surgery, dermatology, or exotic animal medicine requires additional years of residency training after the DVM.
  • Veterinary school typically costs between $100,000 and $200,000 in total tuition, depending on whether the school is public or private.

Core coursework in the first two years focuses on foundational science

The first year and half of veterinary school emphasizes the basic sciences that underpin animal medicine. You study gross anatomy (the structure of organs and systems), histology (tissue structure under a microscope), and physiology (how those systems function). You also take pharmacology, which teaches how drugs work in animal bodies, and biochemistry, which explains the chemical processes inside cells.

Pathology — the study of disease and how it damages tissues — is another major focus. These courses are often taught in lecture halls and laboratory settings, with some hands-on work using animal specimens or models. Many schools also introduce clinical skills early, teaching students how to handle animals safely, take blood samples, and use diagnostic equipment like ultrasound machines.

Clinical training in years three and four involves working with real patients

The second half of veterinary school shifts toward direct patient care. You rotate through different clinical services — small animal medicine and surgery (dogs and cats), large animal medicine (horses and cattle), exotic animal medicine, and sometimes emergency or specialty services. During these rotations, you work under the supervision of licensed veterinarians, performing examinations, assisting in surgeries, and learning to make treatment decisions.

Clinical rotations are where you develop the practical skills that classroom learning cannot teach: how to restrain an anxious animal, how to read an X-ray in real time, how to communicate with owners about treatment options, and how to manage the emotional weight of euthanasia decisions. By the end of your fourth year, you have worked with hundreds of animals and seen a wide range of conditions.

Licensing requires passing the NAVLE and often a state-specific exam

After graduation, you must pass the North American Veterinary Licensing Examination (NAVLE), a comprehensive test covering all areas of veterinary medicine. This exam is administered by the North American Association of Veterinary Medical Boards (AAAVMB) and is required in all 50 U.S. states, Canada, and several other countries.

Many states also require a separate state-specific jurisprudence exam that covers local regulations, animal welfare laws, and prescribing rules. Some states have additional practical exams. Once you pass these exams and meet your state's other requirements — which may include a certain number of supervised practice hours — you receive your veterinary license and can practice independently.

Specialization requires additional residency training after the DVM

If you want to specialize — in surgery, dermatology, cardiology, orthopedics, exotic animal medicine, or another field — you pursue a residency after your DVM. A residency typically lasts two to four years and involves intensive training in a specific area under board-certified specialists. During a residency, you work full-time in that specialty, take additional exams, and often conduct research or publish case studies.

After completing a residency, you can sit for a board certification exam in your specialty, which allows you to call yourself board-certified in that field. This credential signals to employers and clients that you have informed beyond the general DVM. Board certification is optional but common in specialty practices and academic veterinary medicine.

Continuing education is required to maintain your license

Veterinary medicine changes constantly — new drugs are approved, surgical techniques improve, and understanding of animal diseases evolves. Most states require veterinarians to complete a certain number of continuing education hours each year or every few years to keep their license active. These hours can come from conferences, online courses, journal clubs, or university-based programs.

The amount required varies by state. Some require 10 to 20 hours per year; others require 30 or more. Many veterinarians pursue continuing education in areas that interest them or that their practice needs, so a small animal veterinarian might take courses in pain management, while a large animal veterinarian might focus on reproduction or herd health.

Different career paths require different additional training

A general practice veterinarian — the kind you see at a local animal hospital — needs only the DVM and a license. But other paths require more schooling. A veterinary pathologist who diagnoses disease from tissue samples typically completes a residency in anatomic or clinical pathology. A veterinary epidemiologistfood animal veterinarian

Research veterinarians, government veterinarians (working for the USDA or FDA), and academic veterinarians teaching at universities may pursue a PhD in addition to or instead of a residency. The specific path depends on your career goals and the field you want to enter.

Frequently Asked Questions

Can I major in veterinary medicine as an undergraduate?

No. You complete a bachelor's degree in any field while taking prerequisite science courses, then explore to veterinary school. Veterinary medicine is a professional degree you pursue after your undergraduate work, similar to law school or medical school.

How long does it take to become a veterinarian?

A minimum of eight years: four years for a bachelor's degree (with veterinary prerequisites built in) and four years for the DVM. If you pursue a specialty residency, add two to four more years. Some people take longer if they work before explore to veterinary school or if they need extra time to complete prerequisites.

What is the difference between a DVM and a DVS?

They are the same degree with different names. DVM (Doctor of Veterinary Medicine) is used in the United States; DVS (Doctor of Veterinary Science) is used in some other countries. Both represent the same four-year professional veterinary degree and both require licensing to practice.

Do I need a master's degree or PhD to be a veterinarian?

No. The DVM alone is sufficient to practice as a general veterinarian. A master's degree or PhD is only necessary if you want to specialize in research, epidemiology, or certain academic roles. Most practicing veterinarians have only the DVM.

What happens if I fail the NAVLE?

You can retake the exam. Most states allow you to retake it multiple times, though some have limits on how many attempts you can make or how quickly you can retake it. You will need to pay the exam fee again and meet any other state requirements for retesting.
