Veterinarians are physicians for animals, diagnosing and treating diseases, injuries, and conditions in companion animals (dogs, cats, birds, reptiles, exotic pets), livestock (cattle, horses, pigs, sheep, goats, poultry), and wildlife. But veterinary medicine extends far beyond animal care. Veterinarians play critical roles in public health (monitoring and controlling zoonotic diseases that spread from animals to humans, including rabies, avian influenza, and emerging pathogens), food safety (inspecting meat, poultry, and dairy operations to ensure the safety of the food supply), biomedical research (using animal models to study human diseases and develop treatments), wildlife conservation (managing endangered species populations and treating injured wild animals), and military and government service (protecting both human and animal health in federal agencies). The One Health concept, which recognizes the interconnection between human health, animal health, and environmental health, positions veterinary medicine as an increasingly important part of the broader healthcare ecosystem.
Education Pathway
Undergraduate (4 years): Complete a bachelor’s degree with prerequisites similar to pre-med (biology, chemistry, organic chemistry, physics, biochemistry, statistics, English). Veterinary schools also typically require coursework or experience in animal science, zoology, or animal nutrition. Significant animal experience is required for competitive applications: veterinary hospital or clinic volunteering, farm or livestock experience, wildlife rehabilitation, animal shelter work, research involving animals, and experience with multiple species (not just companion animals). GRE®: Most veterinary schools require the GRE® rather than the MCAT®. See our GRE® prep guide. Veterinary School (4 years): The Doctor of Veterinary Medicine (DVM or VMD) curriculum parallels medical school: 2 years of preclinical sciences (anatomy, physiology, pharmacology, pathology, microbiology) covering multiple species, followed by 2 years of clinical rotations in small animal medicine and surgery, large animal medicine, emergency and critical care, radiology, ophthalmology, dermatology, and elective rotations. Apply through VMCAS (Veterinary Medical College Application Service). There are 33 accredited veterinary schools in the U.S. Optional Residency (3 to 4 years): Board certification in veterinary specialties (surgery, internal medicine, oncology, neurology, cardiology, dermatology, emergency and critical care, and others) requires a 3 to 4 year residency after veterinary school. Specialty training is competitive and typically includes a research component.
What Veterinarians Do
Companion Animal Practice: The most common veterinary career path. Companion animal veterinarians examine pets, diagnose illnesses, perform surgeries (spay/neuter, tumor removal, fracture repair, dental procedures), prescribe medications, administer vaccinations, and counsel pet owners on nutrition, behavior, and preventive care. A typical day involves seeing 15 to 25 patients with conditions ranging from routine wellness checks to complex medical cases and surgical emergencies.
Large Animal and Food Animal Practice: Large animal veterinarians work with livestock on farms and ranches, treating illness, performing reproductive management (pregnancy diagnosis, artificial insemination), managing herd health, and ensuring compliance with food safety regulations. This practice setting involves significant travel (farm calls), physical demands, and outdoor work in all weather conditions. Food animal veterinarians play a direct role in the safety and sustainability of the food supply.
Public Health and Research: Veterinarians in public health work for agencies like the CDC, USDA, FDA, and state health departments, monitoring zoonotic diseases, inspecting food processing facilities, responding to disease outbreaks, and developing policies that protect both human and animal health. Research veterinarians work in universities, pharmaceutical companies, and government laboratories, studying diseases, developing vaccines and treatments, and conducting clinical trials. The COVID-19 pandemic highlighted the critical importance of veterinarians in surveillance and response to emerging infectious diseases with zoonotic origins.
Salary and Job Outlook
The median annual salary for veterinarians is approximately $119,100 according to the Bureau of Labor Statistics. Salaries vary significantly by practice type: companion animal practice averages $100,000 to $130,000, while board-certified specialists can earn $175,000 to $300,000+. Veterinary school tuition averages $200,000 to $300,000 for the four-year program, creating a debt-to-income ratio that is a serious concern for the profession (veterinary student debt often exceeds the profession’s earning potential by a wider margin than medical school debt). The profession is projected to grow 19 percent through 2032, driven by increasing pet ownership, growing demand for veterinary specialty care, and expanding roles in public health and food safety.
Advantages and Challenges
Advantages: Working with animals (for students whose primary motivation is animal welfare, there is no substitute), the medical and surgical complexity that rivals human medicine, diverse career paths (clinical practice, research, public health, wildlife conservation, military service), the One Health connection to human healthcare, and the deep bonds formed with patients and their owners.
Challenges: The debt-to-income ratio is the worst among doctoral-level healthcare professions (median debt exceeding $180,000 for a career with a median salary of $119,000), compassion fatigue and burnout are significant (veterinarians have one of the highest rates of suicide among healthcare professionals, driven by emotional demands, financial stress, and access to euthanasia drugs), euthanasia is a routine part of practice that takes an emotional toll, the physical demands are substantial (restraining large animals, standing for long surgeries, being bitten or kicked), and the job market for companion animal positions in desirable urban areas is competitive despite overall growth.
Getting Started
Middle school: Spend time with animals and explore biology. High school: Take science courses, volunteer at animal shelters, veterinary hospitals, and farms. Undergraduate: Complete prerequisites, build extensive and diverse animal experience (companion and large animal), pursue research opportunities, and apply through VMCAS.
Specialty Veterinary Medicine: Veterinary medicine has developed a robust specialty system parallel to human medicine. Board-certified veterinary specialists complete residency training and pass rigorous board examinations in areas including internal medicine, surgery, oncology, cardiology, neurology, dermatology, ophthalmology, emergency and critical care, radiology, anesthesiology, pathology, and behavioral medicine. Specialty hospitals and referral centers provide advanced diagnostic and treatment capabilities (MRI, CT, radiation therapy, laparoscopic surgery, interventional cardiology) that rival human medical technology. Specialty veterinary medicine offers the highest salaries in the profession ($175,000 to $300,000+) but requires 3 to 4 additional years of training beyond veterinary school and the research productivity and competitive application process required for residency positions.
Mental Health in Veterinary Medicine: The veterinary profession faces a serious mental health crisis. Veterinarians experience depression, anxiety, burnout, and suicidal ideation at rates significantly higher than the general population and higher than most other healthcare professions. Contributing factors include the emotional toll of euthanasia (veterinarians euthanize patients regularly, a burden that no other healthcare profession carries), the financial stress of educational debt that often exceeds earning potential, compassion fatigue from caring for suffering animals and their distressed owners, long hours and demanding work environments, and the phenomenon of cyberbullying and online harassment by clients who blame veterinarians for outcomes beyond their control. If you are considering veterinary medicine, take this reality seriously. Develop strong mental health habits, build a support network, and know how to access mental health resources throughout your career. The profession is actively working to address these challenges through wellness programs, student debt reform advocacy, and mental health resources for practitioners. See our mental health and wellness page.
Emerging Opportunities: The veterinary profession is expanding into new areas that create career opportunities beyond traditional clinical practice. Shelter medicine focuses on the health and welfare of animals in shelters and rescue organizations. Conservation medicine addresses the health of wildlife populations and ecosystems. Regulatory medicine involves working for government agencies that oversee food safety, animal welfare, and disease control. Telemedicine (providing veterinary consultations remotely) is growing rapidly and expanding access to care in underserved areas. Veterinary informatics applies data science and technology to veterinary practice management, electronic medical records, and population health surveillance. These emerging fields offer career paths that combine veterinary training with interests in policy, technology, conservation, and public health.
