What You Need to Study to Become a Veterinarian

To become a veterinarian in the United States, you need a Doctor of Veterinary Medicine (DVM) degree from an accredited veterinary school, which takes four years to complete. Before you can enter veterinary school, you must finish a four-year bachelor's degree with specific science courses. After graduation, most states require you to pass the North American Veterinary Licensing Examination (NAVLE) before you can practice.

The total time from high school to a licensed veterinarian is typically eight years — four years of undergraduate study plus four years of veterinary school. Some people add extra time for internships or residencies if they want to specialize in areas like surgery, dentistry, or exotic animal medicine.

Key Takeaways

  • You must earn a bachelor's degree with courses in biology, chemistry, organic chemistry, biochemistry, physics, and mathematics before explore to veterinary school.
  • Veterinary school is a four-year DVM program offered only at accredited schools, and admission is competitive based on grades, test scores, and animal experience.
  • After graduation, you must pass the NAVLE exam and meet your state's licensing requirements before you can legally practice as a veterinarian.
  • Gaining hands-on experience with animals through volunteer work, internships, or jobs at veterinary clinics strengthens your process to veterinary school.
  • Specialization in areas like surgery or emergency medicine requires additional training through internships and residencies after your DVM degree.

Undergraduate Degree Requirements

Your bachelor's degree does not have to be in biology or pre-veterinary studies, but it must include specific science courses that veterinary schools require. These courses typically include general biology, organic chemistry, general chemistry, biochemistry, physics, and mathematics through calculus. Most schools also want to see courses in microbiology, genetics, and animal or cell biology.

Veterinary schools look at your overall grade point average (GPA) and your science GPA separately. A competitive applicant usually has a GPA of 3.5 or higher, though some schools accept students with lower grades if other parts of the process are strong. You should plan to take the Graduate Record Examination (GRE) during your junior or senior year, as most veterinary schools require this test score.

Beyond coursework, veterinary schools want to see that you have spent time around animals and understand what the job involves. This can come from working at a veterinary clinic, shadowing a veterinarian, volunteering at an animal shelter or rescue, or working on a farm. Schools typically want to see at least 200 to 500 hours of animal-related experience, though more is better.

Veterinary School: The Four-Year DVM Program

Veterinary school is a four-year professional program that combines classroom learning with hands-on clinical training. The first two years focus on foundational sciences — anatomy, physiology, pharmacology, pathology, and microbiology — along with courses on animal behavior and nutrition. You will spend time in laboratories and on practice animals learning surgical techniques and diagnostic skills.

The second two years shift toward clinical work. You will rotate through different areas of veterinary medicine, including small animal medicine, large animal medicine, surgery, dentistry, and emergency care. These rotations take place at the veterinary school's teaching hospital or affiliated clinics, where you work under the supervision of licensed veterinarians and gain experience diagnosing and treating real animals.

Admission to veterinary school is competitive. Schools consider your undergraduate GPA, GRE scores, letters of recommendation, your personal statement, and your animal experience. The number of applicants far exceeds the number of spots available — some schools receive over 1,000 applications for 100 positions. Starting your preparation early and building a strong process over several years increases your chances.

Licensing and the NAVLE Exam

After you graduate from veterinary school with your DVM degree, you cannot legally practice as a veterinarian until you pass the North American Veterinary Licensing Examination. This exam tests your knowledge of veterinary medicine and your ability to explore that knowledge to real cases. Most graduates take the NAVLE in the months after graduation, and you typically have a few attempts to pass if needed.

Each state also has its own licensing requirements beyond the NAVLE. Some states require additional state-specific exams, continuing education hours, or fees. A few states have reciprocity agreements that allow you to transfer a license from another state, but most require you to meet their specific requirements. You should check your state's veterinary board website to understand what is needed in your area.

Specialization and Advanced Training

If you want to specialize in a particular area of veterinary medicine — such as surgery, internal medicine, emergency and critical care, dentistry, or exotic animal medicine — you will need additional training beyond your DVM. This usually takes the form of a one- to three-year internship followed by a two- to four-year residency program in your chosen specialty.

Internships are paid positions at veterinary hospitals or universities where you work full-time under supervision, gaining deeper experience in a specific area. Residencies are more advanced and competitive; they are typically offered at veterinary schools or large specialty hospitals. Completing a residency allows you to become board-certified in your specialty through organizations like the American College of Veterinary Surgeons or the American College of Veterinary Internal Medicine.

Specialization is optional. Many veterinarians work in general practice their entire career without pursuing additional credentials. However, specialists typically earn higher salaries and may have more job options in urban areas or at large animal hospitals.

Continuing Education After Licensure

Once you are licensed, you must complete continuing education hours to keep your license active. The number of hours required varies by state — some require 20 to 30 hours per year, while others require less. These hours can come from attending conferences, taking online courses, reading veterinary journals, or teaching other veterinarians.

Continuing education keeps your knowledge current as veterinary medicine evolves. New drugs, surgical techniques, and diagnostic tools are developed regularly, and staying informed helps you provide the best care to your patients. Many veterinarians view this requirement as an opportunity to deepen their informed in areas that interest them.

Cost and Time Investment

Veterinary school is expensive. Tuition and fees at public veterinary schools typically range from $15,000 to $30,000 per year, while private schools can cost $40,000 to $60,000 per year. Over four years, the total cost can reach $60,000 to $240,000 depending on the school and whether you attend in-state or out-of-state. Many graduates finish with student loan debt that takes years to repay.

The time investment is also significant. Between your bachelor's degree, veterinary school, and licensing exams, you are looking at eight years minimum before you can practice independently. If you pursue specialization, add another three to seven years. This long training period means you will not start earning a veterinarian's salary until your late twenties or early thirties.

Frequently Asked Questions

Can I become a veterinarian without a four-year bachelor's degree?

No. Veterinary schools require a bachelor's degree with specific science courses before you can explore. You cannot skip this step or substitute it with other credentials. Some people complete their bachelor's degree while working or attending school part-time, but the degree itself is mandatory.

What if I did not take the right science courses in my bachelor's degree?

You can take the missing courses after you finish your degree. Many people complete prerequisite science courses at community colleges or through post-baccalaureate programs. This adds time and cost, but it allows you to meet veterinary school requirements if your original degree did not include them.

How many times can I take the NAVLE if I fail?

You can retake the NAVLE, but the number of attempts and waiting periods between attempts vary by state. Most states allow multiple attempts, but some limit you to a certain number within a set timeframe. Check your state's veterinary board rules for specific policies.

Do I need to specialize to have a good career as a veterinarian?

No. Many veterinarians work in general practice at small animal clinics, large animal practices, or mixed-animal facilities without any specialization. Specialization is optional and is mainly for people who want to focus on a specific area or earn higher income. A DVM degree alone qualifies you for most veterinary jobs.

Can I practice as a veterinarian in another country with a U.S. DVM degree?

It depends on the country. Some countries recognize U.S. veterinary degrees, while others require you to pass their own exams or complete additional training. If you plan to work internationally, research the requirements in that country before you finish your degree.
