Veterinarians are not medical doctors, but they complete medical training that is similar in length and rigor

A veterinarian holds a Doctor of Veterinary Medicine (DVM) degree, which is a doctoral degree in medicine. However, they are not an MD (Medical Doctor) or DO (Doctor of Osteopathic Medicine), which are the titles for human physicians. The difference is not in the level of training but in the field: veterinarians study animal anatomy, physiology, and disease instead of human anatomy and disease.

Both paths require four years of professional school after a bachelor's degree, plus prerequisite coursework. Both involve clinical rotations, board exams, and licensing. A veterinarian's training is as demanding as a physician's—it is straightforward applied to a different species. Some veterinarians go on to specialize further, earning additional certifications in surgery, cardiology, or other fields, much as human doctors do.

Key Takeaways

  • Veterinarians earn a DVM degree through four years of veterinary school, which requires the same level of academic rigor as medical school for human doctors.
  • The title "veterinarian" is legally protected; only graduates of accredited veterinary schools who pass licensing exams can use it.
  • Veterinary training covers diagnosis, surgery, pharmacology, and disease management, but for animals rather than humans.
  • Some veterinarians pursue board certification in specialties like orthopedic surgery or internal medicine, similar to how human physicians specialize.

How veterinary school compares to medical school

Both veterinary and medical schools require a bachelor's degree first, along with prerequisite courses in chemistry, biology, organic chemistry, and physics. Admission to either program is competitive and based on GPA, entrance exam scores (the MCAT for medical school, the GRE or veterinary-specific exams for vet school), and clinical experience.

Veterinary school lasts four years, as does medical school. The curriculum covers anatomy, physiology, pharmacology, pathology, and clinical diagnosis—the same core subjects as medical school, but applied to animals. In the final two years, veterinary students work with live animals under supervision, performing exams, taking radiographs, drawing blood, and assisting in surgery. Medical students do the same with human patients.

After graduation, veterinarians must pass the North American Veterinary Licensing Examination (NAVLE) to practice. Medical doctors must pass the United States Medical Licensing Examination (USMLE) or the Comprehensive Osteopathic Medical Licensing Examination (COMLEX). Both are rigorous, multi-part exams that test knowledge and clinical judgment.

What veterinarians are trained to do

Veterinarians diagnose and treat disease, perform surgery, prescribe medication, and manage preventive care—the same core functions as human physicians. They take medical histories, perform physical exams, order and interpret lab work and imaging, and develop treatment plans. They can prescribe controlled substances and perform procedures ranging from routine vaccinations to complex orthopedic surgery.

The scope of practice varies by state, but veterinarians in all states can perform surgery, dental work, and anesthesia. Some states allow veterinarians to perform certain procedures on exotic animals or wildlife that would be outside the scope of a typical small-animal or large-animal practice. Veterinarians also work in public health, food safety, research, and disease surveillance—roles that require the same epidemiological and diagnostic training as human medicine.

Why veterinarians are not called "medical doctors"

The title "medical doctor" or "MD" is reserved by law for physicians who have completed medical school accredited by the Liaison Committee on Medical Education (LCME) or the American Osteopathic Association (AOA). Veterinarians graduate from schools accredited by the American Veterinary Medical Association (AVMA), which is a separate accrediting body. The distinction is historical and regulatory, not a reflection of training quality.

Veterinarians may use the title "Doctor" in conversation and on business cards—many do—but the credential "DVM" or "VMD" (Doctor of Veterinary Medicine, the older title still used by some schools) is what legally identifies them. Using "MD" without having earned it from an LCME- or AOA-accredited medical school is illegal and constitutes fraud.

Specialization and advanced training for veterinarians

After earning a DVM and passing the NAVLE, veterinarians can pursue board certification in a specialty. The American Board of Veterinary Specialties (ABVS) recognizes more than 20 specialties, including surgery, internal medicine, cardiology, oncology, dermatology, and emergency and critical care. To become board-certified, a veterinarian typically completes a residency (two to four years of advanced training) and passes a specialty exam.

This pathway mirrors human medicine closely. A human physician completes medical school, passes the USMLE, and then enters a residency in their chosen field. A veterinarian does the same, except the residency is in veterinary surgery or veterinary internal medicine, and the board is the ABVS rather than the American Board of Medical Specialties (ABMS).

Where veterinarians work and what they earn

Veterinarians work in private practice (small-animal clinics, equine hospitals, large-animal farms), emergency and specialty hospitals, research institutions, government agencies, and industry. The Bureau of Labor Statistics tracks veterinarian employment and salary data, though the figures vary by location, experience, and specialization. Veterinarians in rural areas or specialized fields like equine surgery often earn differently than those in urban small-animal practices.

The path to becoming a veterinarian requires the same commitment as becoming a human physician: years of prerequisite coursework, a competitive entrance exam, four years of professional school, clinical training, and a licensing exam. The main difference is the population served—animals instead of humans—not the depth or rigor of the training.

Frequently Asked Questions

Can a veterinarian treat humans?

No. Veterinarians are trained in animal anatomy and physiology, not human medicine. Treating a human patient without a medical license is illegal. Some veterinary knowledge overlaps with human medicine—pharmacology, for instance—but a DVM does not may have access to someone to practice human medicine.

Is a DVM the same as an MD?

No. Both are doctoral degrees in medicine, but an MD is earned from a human medical school and qualifies someone to practice human medicine. A DVM is earned from a veterinary school and qualifies someone to practice veterinary medicine. The training is similar in length and rigor but covers different subjects.

Do veterinarians have to pass a licensing exam?

Yes. All veterinarians must pass the North American Veterinary Licensing Examination (NAVLE) before they can practice. Some states also require additional state-specific exams. Licensing ensures that veterinarians meet a standard of knowledge and competence.

Can a veterinarian become a human doctor?

A veterinarian cannot use their DVM to practice human medicine. However, a veterinarian could explore to medical school if they wanted to become an MD or DO. Medical schools would evaluate their process like any other, though some prerequisite coursework might already be completed.

What is the difference between a DVM and a VMD?

DVM (Doctor of Veterinary Medicine) and VMD (Veterinariae Medicinae Doctor) are the same credential with different Latin word orders. Most schools now use DVM, but some older institutions still award the VMD. Both may have access to a graduate to take the NAVLE and practice as a veterinarian.
