A vet is a doctor trained to diagnose and treat illness and injury in animals

Veterinarian is the formal title; vet is the everyday word for the same person. A vet has completed a four-year veterinary degree after undergraduate study, passed licensing exams in their state, and holds a current license to practice. They examine animals, run diagnostic tests, prescribe medication, perform surgery, and advise owners on nutrition, behavior, and preventive care.

The work is similar to human medicine but adapted for animals that cannot describe their symptoms in words. A vet learns to read body language, palpate (feel) for problems under the skin, and recognize species-specific diseases. They work with dogs, cats, birds, rabbits, horses, livestock, and exotic animals depending on their training and practice focus.

Most vets work in small-animal clinics treating pets, but others specialize in large animals (horses, cattle), exotic species, laboratory animals, or wildlife. Some work in research, public health, or food safety. The title "vet" applies to all of them.

Key Takeaways

  • A vet is a licensed medical professional with a four-year degree and state licensure, not a pet groomer or trainer.
  • Vets diagnose disease, prescribe medication, perform surgery, and give preventive care information for animals that cannot describe their own symptoms.
  • Most vets in private practice treat dogs and cats, but some specialize in horses, exotic pets, livestock, or wildlife.
  • You should call a vet when your pet shows signs of illness, injury, or behavior change, or for routine checkups and vaccinations.
  • Emergency vets are available after hours and on weekends for injuries, difficulty breathing, poisoning, or sudden severe illness.

When to call your regular vet

Call your vet for a routine appointment if your pet needs a checkup, vaccinations, dental cleaning, or preventive care. Most vets recommend annual exams for healthy adult pets and twice-yearly exams for senior animals (usually age seven and older, though this varies by species). These visits catch early signs of disease before symptoms become severe.

Also call for non-emergency illness or injury: vomiting or diarrhea lasting more than a day, limping, ear infections, skin problems, behavioral changes, weight loss, or difficulty eating. Your vet will examine your pet, may run blood work or imaging, and recommend treatment. Many conditions are manageable if caught early.

Routine appointments usually require scheduling days or weeks in advance. Call during business hours and expect to wait for an opening unless your vet has same-day slots.

When to go to an emergency vet

Emergency vets handle urgent situations that cannot wait for a regular appointment. Go to an emergency clinic or animal hospital if your pet is having difficulty breathing, choking, unconscious, severely bleeding, unable to urinate or defecate, in obvious severe pain, seizing, or hit by a car. Poisoning (including chocolate, xylitol, antifreeze, or medications) also requires when ready care.

Emergency clinics are open nights, weekends, and holidays when regular vets are closed. They are more expensive than routine visits because they staff veterinarians and technicians around the clock and have surgical facilities ready. Call ahead if you can so they know you are coming, but do not delay transport to your pet if it is a life-threatening situation.

If you are unsure whether your pet needs emergency care, call your regular vet's after-hours line or the emergency clinic directly. They can advise whether to come in or wait until morning.

What happens during a vet visit

A vet visit typically starts with a technician taking your pet's weight, temperature, heart rate, and respiratory rate. They ask about your pet's diet, behavior, bathroom habits, and any symptoms you have noticed. This information helps the vet focus the exam.

The vet then examines your pet from nose to tail: looking at eyes, ears, and mouth; listening to the heart and lungs with a stethoscope; feeling the abdomen for lumps or pain; checking joints and limbs; and observing gait and behavior. They may recommend blood work, urinalysis, X-rays, ultrasound, or other tests depending on what they find or what you report.

After the exam, the vet discusses findings with you, explains any diagnosis, and recommends treatment options. Treatment might be medication, dietary change, surgery, physical therapy, or monitoring at home. The vet will explain costs and answer questions before proceeding.

The difference between a vet and other pet professionals

A veterinary technician or vet tech is trained to information the vet but is not a veterinarian. They draw blood, take X-rays, clean teeth, monitor anesthesia during surgery, and handle restraint and basic care. They have completed a two-year or four-year program and are licensed in most states, but they cannot diagnose disease or prescribe medication without a vet's direction.

A pet groomer bathes, brushes, and trims your pet's coat and nails. They are not trained in medicine and cannot diagnose or treat health problems. A dog trainer or behaviorist works on behavior and obedience, not medical issues. A pet sitter or dog walker provides care and exercise but is not a medical professional.

If your pet has a medical problem, only a licensed vet can diagnose and treat it. Groomers, trainers, and sitters can notice signs of illness and alert you to call a vet, but they cannot provide medical care.

How to find and choose a vet

Start by asking friends, family, or neighbors for recommendations. You can also search online for vets in your area and read reviews, but remember that reviews reflect individual experiences and may not predict your own. Call a few clinics and ask about their hours, whether they accept new patients, and what services they offer.

Visit the clinic before scheduling an appointment if you can. Look at cleanliness, organization, and how staff interact with animals and owners. Ask whether the vet has experience with your species or breed, especially if you have an exotic pet or a breed with known health issues.

Cost varies widely by location and clinic. Some clinics are nonprofit or low-cost; others are full-service with advanced equipment and specialists. Choose based on your budget, your pet's needs, and how comfortable you feel with the vet and staff. It is normal to try a clinic and switch if it is not a good fit.

What vets study and how they are licensed

Veterinary school is a four-year graduate program that requires prerequisite science courses (biology, chemistry, organic chemistry, physics, biochemistry). Students learn anatomy, physiology, pharmacology, surgery, and medicine for multiple species. They also study public health, food safety, and ethics.

After graduation, vets must pass the North American Veterinary Licensing Examination (NAVLE) to be licensed. Each state has its own licensing board and requirements; some states require additional exams or continuing education. Licensed vets must renew their license periodically and complete continuing education hours to stay current.

Some vets pursue additional training in a specialty such as surgery, cardiology, dermatology, or orthopedics. Board certification in a specialty requires extra years of training and passing a specialty exam, but it is not required to practice general veterinary medicine.

Frequently Asked Questions

How often should I take my pet to the vet?

Healthy adult pets usually need an annual exam. Puppies and kittens need multiple visits in their first year for vaccinations and checkups. Senior pets (usually seven and older) benefit from twice-yearly exams because age-related diseases develop faster. If your pet has a chronic condition, your vet may recommend more frequent visits.

Can a vet prescribe medication over the phone?

Most vets will not prescribe medication without examining your pet first, because they need to confirm the diagnosis. Some established clients can get refills of ongoing medications by phone or online, but new problems require an in-person visit. Emergency situations may be an exception; call your vet to ask.

What should I do if I cannot afford vet care?

Look for low-cost clinics in your area, which charge reduced fees based on income. Some animal shelters and rescue organizations offer discounted services. Ask your regular vet about payment plans or whether they know of financial resources. Pet insurance and care credit programs can help spread costs over time, though they require enrollment before illness occurs.

Is a vet the same as a veterinarian?

Yes. "Vet" is the informal, everyday term for a veterinarian. Both words refer to the same licensed medical professional. You might also hear "DVM" (Doctor of Veterinary Medicine) or "VMD" (Veterinariae Medicinae Doctoris), which are the degree titles vets earn.

What is the difference between a vet and an animal hospital?

A vet is a person; an animal hospital or veterinary clinic is a building where vets work. A small clinic might have one or two vets, while a large animal hospital might have many vets and specialists, plus surgical suites and advanced equipment. Both are run by licensed veterinarians.
