Veterinarians do not attend medical school, but they complete a similarly rigorous education called veterinary school

Veterinarians earn a degree called a Doctor of Veterinary Medicine (DVM) or, in some countries, a Bachelor of Veterinary Science (BVSc). This is a separate professional degree from the MD (Medical Doctor) that human physicians earn. Veterinary school is a four-year graduate program that requires specific prerequisites and entrance exams, much like medical school does for doctors, but the curriculum focuses on animal anatomy, physiology, and disease rather than human medicine.

The confusion often arises because both paths lead to a "doctor" title and both require advanced education after a bachelor's degree. However, veterinarians and human doctors train in different schools, study different systems, and take different licensing exams. A veterinarian cannot practice human medicine, and a human doctor cannot practice veterinary medicine, even though some of the foundational science overlaps.

Key Takeaways

  • Veterinarians attend four-year veterinary schools, not medical schools, and earn a DVM degree instead of an MD.
  • Admission to veterinary school requires a bachelor's degree, specific science courses, a competitive entrance exam (the GRE or veterinary-specific exam), and often veterinary experience.
  • Veterinary school covers animal anatomy, pharmacology, surgery, and disease diagnosis across multiple species, not human medicine.
  • After graduation, veterinarians must pass a licensing exam called the NAVLE (North American Veterinary Licensing Examination) to practice in the United States.
  • Some veterinarians pursue additional specialty training through internships and residencies, similar to how some human doctors specialize.

What veterinary school requires before admission

To enter veterinary school, you must first complete a bachelor's degree from an accredited college or university. Unlike medical school, you do not have to major in biology or chemistry, but you must complete specific prerequisite courses. These typically include general biology, organic chemistry, biochemistry, physics, and sometimes microbiology or animal science. Different veterinary schools have slightly different requirements, so applicants usually check the schools they are interested in before choosing their coursework.

After completing your bachelor's degree, you take an entrance exam. Most veterinary schools in the United States require the Graduate Record Examination (GRE), though some schools use the Veterinary Medical College Admission Test (VMCAT). Your score, your undergraduate GPA, and your performance in science courses all factor into admission decisions. Veterinary schools are competitive, and many applicants are rejected each year.

Most veterinary schools also expect applicants to have hands-on experience with animals. This might be veterinary clinic work, shadowing a veterinarian, farm experience, or research involving animals. Schools want to see that you understand what the job actually involves and are committed to it. The amount of experience required varies by school, but 100 to 200 hours is common.

What veterinary school teaches over four years

The first two years of veterinary school focus on foundational science. You study animal anatomy (the structure of animal bodies), physiology (how animal bodies function), pharmacology (how drugs work in animals), and pathology (how disease develops). You also learn about different animal species—dogs, cats, horses, cattle, birds, and exotic animals—because a veterinarian may treat any of them. This is different from medical school, where the focus is exclusively on human anatomy and physiology.

The second half of veterinary school shifts toward clinical practice. You take courses in surgery, internal medicine, dentistry, reproduction, and nutrition. You also begin working in teaching hospitals or clinics, where you examine real animals under supervision, perform procedures, and diagnose conditions. By the end of your fourth year, you are spending most of your time in hands-on clinical work rather than in lectures.

Veterinary school also includes courses on business and ethics, because many veterinarians eventually own or manage a practice. You learn about client communication, medical record-keeping, and the legal and ethical responsibilities of veterinary medicine. Some schools also require courses on public health or food safety, especially if they have programs focused on livestock or food-producing animals.

How veterinary licensing works after graduation

After you graduate from veterinary school with your DVM, you cannot practice as a veterinarian until you pass the North American Veterinary Licensing Examination (NAVLE). This is a computer-based test administered by the North American Association of State Veterinary Boards (NASB). The exam covers all the major areas of veterinary medicine—surgery, internal medicine, pharmacology, and more—and tests whether you can make safe, competent decisions about animal care.

Each state also has its own licensing board and may require additional exams or paperwork beyond the NAVLE. Some states require a state-specific jurisprudence exam that covers that state's veterinary laws and regulations. Once you pass the NAVLE and meet your state's requirements, you receive a veterinary license and can legally practice.

Specialty training and advanced degrees for veterinarians

After earning a DVM and passing the NAVLE, some veterinarians pursue additional training in a specialty. This might be surgery, cardiology, dermatology, or any of dozens of other fields. To specialize, a veterinarian typically completes an internship (usually one year) followed by a residency (usually two to three years) in their chosen specialty. During this time, they work at a teaching hospital or referral center and study for board certification exams.

Some veterinarians also earn a master's degree or PhD in fields like epidemiology, public health, or animal behavior. These advanced degrees are separate from the DVM but often pursued by veterinarians who want to work in research, government, or public health rather than in clinical practice. A veterinarian with a PhD is not the same as a human doctor with a PhD—the credentials mean different things and prepare you for different careers.

How veterinary training differs from human medical training

The biggest difference is that veterinarians study multiple species, while human doctors study only human anatomy and physiology. A veterinarian must understand how a dog's heart differs from a cat's heart, how a horse's digestive system works, and how to treat a bird or a rabbit. Human doctors never need this knowledge because they only treat humans.

Another difference is that veterinarians often work alone or in small teams, making independent decisions about diagnosis and treatment. Human doctors in hospitals often work within larger teams and may consult specialists more frequently. Veterinarians also spend more time on preventive care and wellness—vaccines, dental cleaning, weight management—whereas human medicine often focuses on treating disease after it develops.

Finally, veterinarians must communicate with animal owners rather than with patients. You cannot ask a dog what hurts or whether it has been taking its medication. Veterinarians rely on owner observations, physical examination, and diagnostic tests, which requires a different skill set than human medicine.

Frequently Asked Questions

Can a veterinarian become a human doctor?

A veterinarian cannot automatically become a human doctor. They would need to explore to medical school and complete the full four-year program, just like anyone else. Some veterinarians have done this, but it requires starting over with medical school education. The two degrees are not interchangeable.

Is veterinary school harder than medical school?

Both are competitive and rigorous, but they are difficult in different ways. Veterinary school requires mastery of multiple animal species and systems, while medical school focuses deeply on human medicine. Admission rates and course difficulty vary by school. Most experts say they are roughly equivalent in overall difficulty, not that one is objectively harder than the other.

How long does it take to become a veterinarian?

The minimum is six years after high school: four years for a bachelor's degree with veterinary prerequisites, then four years of veterinary school. If you pursue a specialty like surgery, add another three to four years for internship and residency. Most veterinarians are practicing by their late twenties or early thirties.

Do veterinarians take the same exams as human doctors?

No. Veterinarians take the NAVLE (North American Veterinary Licensing Examination), while human doctors take the USMLE (United States Medical Licensing Examination) or COMLEX (for osteopathic doctors). These are completely separate exams testing different knowledge and skills.

What is the difference between a DVM and a VMD?

Both are veterinary degrees earned from accredited veterinary schools in the United States. DVM stands for Doctor of Veterinary Medicine, and VMD stands for Veterinariae Medicinae Doctoris (a Latin form of the same degree). The University of Pennsylvania uses VMD, while most other schools use DVM, but they represent the same credential and qualification.
