In the United States, AVMA-recognized specialty organizations certify veterinarians who complete advanced training and meet that organization’s own requirements. AAHA’s 2025 referral guidelines count 22 recognized specialty organizations and 46 specialty types. Those counts are a snapshot, so check the AVMA’s directory of recognized specialties for the current list.
What a veterinary specialty actually is
A specialty is an area of practice in which a veterinarian has earned formal recognition through a specialty organization. The recognition comes from the organization, not from the veterinarian’s interests or the amount of time spent on a topic. A general practitioner who sees many cases of skin disease, for example, is not a dermatologist unless he or she has been certified by the relevant specialty board.
Specialties are not organized in a single way. Some are defined by species or by a type of clinical practice, such as avian or equine medicine. Others are defined by a discipline that cuts across species, such as surgery, cardiology, pathology, or behavior. Readers will see both kinds of label in the same directory, so it helps to keep the distinction in mind when comparing them.
A practical map of the field
An alphabetical list of specialties is hard to use, so the field is easier to understand in three clusters.
#1 Best Overall
Species and clinical-practice focus
ABVP, the American Board of Veterinary Practitioners, lists 12 recognized practice categories. Examples include:
- Avian practice
- Equine practice
- Feline practice
- Food animal practice
- Dairy and beef cattle practice
- Swine health management
- Reptile and amphibian practice
- Exotic companion mammal practice
- Shelter medicine
Clinical disciplines
AAHA’s 2025 referral guidelines describe a range of recognized disciplines and subfields. Commonly cited examples include internal medicine (with subfields such as cardiology, neurology, oncology, and nutrition), surgery, anesthesia and analgesia, dermatology, ophthalmology, emergency and critical care, dentistry, and behavior. These areas usually involve managing a particular organ system, a type of disease, or a clinical service.
Diagnostic, population, and other work
Some specialties focus less on treating individual patients directly and more on diagnosis, laboratory work, or whole populations of animals. Examples in AAHA’s listing include clinical pathology, anatomic pathology, microbiology, laboratory animal medicine, animal welfare, toxicology, and theriogenology (reproduction).
A specialty name tells you the area of certified expertise. It does not tell you exactly which patients, services, or procedures a given specialist handles. Those vary by specialist, practice, and region, so ask the practice directly.
Rank #2
What does a veterinary specialist do?
Specialists generally manage patients with complex conditions or needs that call for advanced diagnostics or treatment. Their work commonly includes:
- Consultation: reviewing a case and advising the referring veterinarian on diagnosis or a treatment plan.
- Diagnostic interpretation: reading imaging, laboratory, or pathology results that require specialized training.
- Procedures: performing surgery or other advanced interventions within their field.
- Acute or critical care: managing urgent cases in emergency or intensive settings.
- Ongoing case management: following a referred problem over time.
Not every specialist does all of these. Some work mainly as consultants, while others take on a referred problem for its full course. The care relationship is part of the picture, as covered below.
How does a veterinarian become a specialist?
The general path is consistent: a veterinarian first earns a veterinary degree, then completes advanced, specialty-specific training and satisfies the credentialing and examination rules of the relevant specialty organization. The details differ by specialty. There is no single pathway across all specialties, and readers should not assume that every candidate follows the same internship-plus-residency sequence.
One example: ABVP’s two routes
ABVP shows how much these rules can vary. Its website describes two routes to board certification:

These are ABVP-specific rules. They are not a universal veterinary-specialty timeline, and other organizations set their own requirements. For the current requirements of any specialty, check its certifying organization.
Surgery and the word “specialist”
The American College of Veterinary Surgeons (ACVS) distinguishes large-animal and small-animal surgery designations. Its terminology guidance says the title “specialist” may be used only for veterinarians certified by an AVMA-recognized specialty organization. When describing a surgeon or diplomate, follow the college’s precise rules on how to state certification status.
Using the terms accurately
“Veterinary specialist” and “board-certified” are formal credentials. A veterinarian who simply practices in an area, reads widely about it, or has a strong interest in it has not earned either term. ABVP makes a related point in its own words: “Most veterinarians performing broad-based clinical practice are not board-certified.” That sentence describes the scope of board certification. It is not a judgment about the quality of general practice, which is the foundation of most pet care.
How primary care and specialty care fit together
AAHA’s guidelines describe two teams. The primary care team is the group in a primary-care practice responsible for establishing and maintaining the veterinary-client-patient relationship for ongoing care. The specialty care team provides care for complex conditions or needs that call for advanced diagnostics and treatments.

A referral is a collaboration around a specific clinical need. In practice:
- The specialist may direct care for the referred condition while the referral is active.
- When the referral ends, the primary-care veterinarian generally resumes that role.
- A referral may be a single consultation or may extend into longer-term oversight.
Questions to ask your veterinarian
These questions are based on the referral roles AAHA describes. They are a way to organize the conversation, not individualized medical advice.
- What exactly will the specialist handle, and what stays with you?
- Will the specialist see my pet once, or will they manage the problem over time?
- How will the two teams share records, test results, and updates?
- Who will coordinate follow-up, and who should I contact with questions?
How to compare specialties
When you are trying to understand a referral or weighing a career direction, five axes make the differences clearer:
- Patients: the species, age, or population served.
- Problem area: the organ system, disease type, diagnostic focus, or population need.
- Day-to-day work: consultation, interpretation, procedures, acute care, case management, research, or population-level work.
- Training and credential: the certifying organization, the available pathways, and that specialty’s current requirements.
- Care relationship: whether the specialist consults, temporarily takes over a referred problem, or provides ongoing follow-up.
The sources behind this overview do not provide a comparable, current picture of compensation, working hours, match rates, or competitiveness across specialties. Those factors should be researched separately for any specialty you are considering.

How many specialists are there?
Several figures are often quoted, and they come from different sources, dates, and counting methods. Keep each one attached to its source:
- 22 specialty organizations and 46 specialty types: stated in the introduction to AAHA’s 2025 referral guidelines (AAHA, Introduction, Definitions and Recognized Veterinary Specialties (2025)).
- More than 16,500 veterinarians with diplomate status in one or more organizations: reported in AAHA’s 2025 referral guidelines. The passage does not give a count date.
- About 18,000 diplomates worldwide as of December 31, 2024: reported in AAHA’s article “Know your veterinary specialties,” published July 17, 2025 (AAHA, Know your veterinary specialties). AAHA notes that some veterinarians hold more than one specialty and that totals can fluctuate.
The last two totals are not identical and should not be merged into one count. Neither should be treated as an exact, current census.
Where to check current information
Specialty names, descriptions, and certification requirements change over time. For the current list of recognized specialties, use the AVMA’s directory of recognized specialties. For the rules of a particular field, go to that specialty’s certifying organization. For example, ABVP’s “Become a Specialist” page is at abvp.com/become-a-specialist/, and ACVS’s terminology guidance is at ACVS certification status terminology and use.
Keep in mind that this overview uses U.S. AVMA-recognized terminology. Other countries may use different recognition and certification systems.
