A veterinarian is a licensed medical professional who diagnoses and treats illness and injury in animals

Veterinarians work with pets, livestock, wildlife, and zoo animals. They perform physical exams, order and read diagnostic tests like X-rays and blood work, prescribe medication, perform surgery, and advise owners on nutrition, behavior, and preventive care. A veterinarian's job is to keep animals healthy and relieve their suffering when they are sick or hurt.

Most people encounter veterinarians through a local animal clinic or hospital when they own a pet. But veterinarians also work in research facilities, government agencies, farms, zoos, and wildlife rehabilitation centers. Some specialize in a single species or type of medicine — for example, a veterinarian might focus only on horses, or only on dental surgery, or only on exotic birds.

Key Takeaways

  • Veterinarians must complete four years of veterinary school after earning a bachelor's degree, then pass a licensing exam in their state.
  • A routine veterinary visit typically includes a physical exam, discussion of the animal's diet and behavior, and preventive care like vaccinations.
  • Veterinarians can prescribe medication, perform surgery, and order diagnostic imaging, but they cannot treat humans.
  • The cost of veterinary care varies widely depending on the type of animal, the procedure, and your location.

How veterinarians are trained and licensed

To become a veterinarian in the United States, a person must first earn a bachelor's degree, usually with coursework in biology, chemistry, and animal science. Then they attend veterinary school, which takes four years. Veterinary schools are competitive — admission requires strong grades, test scores, and often volunteer or work experience with animals.

After graduation, a new veterinarian must pass the North American Veterinary Licensing Examination (NAVLE) to practice. Each state also has its own licensing requirements, which may include additional exams or paperwork. Once licensed, a veterinarian can work independently or as part of a clinic or hospital staff. Many states require veterinarians to complete continuing education hours each year to keep their license active.

What happens during a routine veterinary visit

A typical visit starts with the veterinarian asking about the animal's medical history, current diet, behavior, and any symptoms the owner has noticed. The veterinarian then performs a physical exam — checking the animal's weight, temperature, heart rate, and breathing, and palpating (feeling) the abdomen and joints to detect pain or abnormalities.

For a young, healthy animal, the visit may include vaccinations to prevent common diseases. For an older animal or one with a known condition, the veterinarian may recommend blood work, urinalysis, or imaging like X-rays or ultrasound. If the animal is sick or injured, the veterinarian will discuss treatment options, which might include medication, dietary changes, or referral to a specialist.

Surgical procedures and emergency care

Veterinarians perform a wide range of surgeries, from routine spaying and neutering to tumor removal, orthopedic repair, and emergency abdominal surgery. These procedures require the same sterile technique and anesthesia management as human surgery. Many veterinary clinics have operating rooms equipped with anesthesia machines, surgical lights, and monitoring equipment.

Emergency veterinary hospitals operate 24 hours a day to handle acute injuries and illnesses — hit-by-car trauma, severe bleeding, difficulty breathing, or sudden paralysis. An emergency veterinarian stabilizes the animal, runs diagnostic tests, and decides whether surgery or intensive care is needed. Emergency care is typically more expensive than routine care because it requires when ready attention and often involves advanced diagnostics and monitoring.

Specializations within veterinary medicine

Just as human doctors specialize, veterinarians can pursue additional training in specific areas. A veterinary surgeon completes a residency in surgical techniques and may focus on orthopedics, soft tissue surgery, or neurosurgery. A veterinary cardiologist specializes in heart disease. A veterinary oncologist treats cancer. Other specialties include dermatology, dentistry, internal medicine, and exotic animal medicine.

To become a specialist, a veterinarian typically completes a residency program lasting two to five years, during which they work under the supervision of an experienced specialist. Some residencies lead to board certification, which means the veterinarian has passed an additional exam and met specific training requirements. Specialist veterinarians usually work at larger hospitals or referral centers and charge higher fees than general practitioners.

The difference between a veterinarian and a veterinary technician

A veterinary technician is a trained professional who assists the veterinarian but is not a veterinarian. Technicians typically complete a two-year associate degree program and pass a licensing exam. They perform tasks like drawing blood, taking X-rays, assisting in surgery, administering medication, and educating owners about pet care.

A veterinarian has the authority to diagnose disease, prescribe medication, and perform surgery. A veterinary technician cannot do these things independently — they work under the direction of a licensed veterinarian. In a typical clinic, the veterinarian examines the animal and makes treatment decisions, while the technician carries out those decisions and handles much of the hands-on care.

Cost and what to expect to pay

The cost of veterinary care depends on the type of animal, the procedure, your location, and whether you visit a general practice or a specialty hospital. A routine wellness exam for a dog or cat typically costs between $50 and $150. Vaccinations, blood work, and dental cleaning add to that cost. Spaying or neutering a dog or cat usually ranges from $200 to $500.

Emergency care and surgery are significantly more expensive. An emergency visit might cost $500 to $2,000 depending on what tests and treatment are needed. Major surgery can cost $1,000 to $5,000 or more. Some owners purchase pet insurance to help cover unexpected costs, though insurance policies vary widely in what they cover and what they cost.

Frequently Asked Questions

Do I need to take my pet to the vet every year?

Most veterinarians recommend at least one wellness visit per year for adult pets, and more frequent visits for puppies, kittens, and senior animals. These visits allow the veterinarian to catch health problems early and keep vaccinations current. Your veterinarian can recommend a schedule based on your pet's age and health status.

Can a veterinarian prescribe medication for my pet?

Yes. A veterinarian can prescribe antibiotics, pain medication, allergy medication, and many other drugs. Some medications are available only by prescription. The veterinarian will explain how to give the medication, how long to continue it, and what side effects to watch for.

What should I do if my pet needs care after hours?

Most general veterinary clinics close in the evening and on weekends. For emergencies outside those hours, look for an emergency veterinary hospital in your area — these operate 24 hours and handle urgent cases. Call ahead if possible so they can prepare for your arrival. Emergency care costs more than routine care.

How do I find a good veterinarian?

Ask friends, family, and neighbors for recommendations. Check online reviews and call clinics to ask about their experience with your type of animal, their hours, and their fees. Many clinics offer a first visit at a reduced rate so you can meet the veterinarian and see the facility before committing.

Can a veterinarian treat exotic animals like birds or reptiles?

Some veterinarians treat exotic animals, but not all. General practice clinics often focus on dogs and cats. If you own a bird, reptile, rabbit, or other exotic pet, ask the clinic whether they have experience with that species before scheduling an appointment. Specialty exotic animal hospitals exist in larger cities.
