Veterinary medicine is widely practiced, both with and without professional supervision. Professional care is most often led by a
veterinary physician (also known as a veterinarian, veterinary surgeon, or "vet"), but also by
paraveterinary workers, such as veterinary nurses, veterinary technicians, and veterinary assistants.

after observing the devastation being caused by
cattle plague to the French herds, Bourgelat devoted his time to seeking out a remedy. This resulted in founding a veterinary school in Lyon in 1761, from which establishment he dispatched students to combat the disease; in a short time, the plague was stayed and the health of stock restored, through the assistance rendered to agriculture by veterinary science and art.
[J.L.Lupton, "Modern Practical Farriery", 1879, in the section: "The Diseases of Cattle Sheep and Pigs" pp. 1] The school received immediate international recognition in the 18th century and its pedagogical model drew on the existing fields of human medicine,

Thomas Burgess, began to take up the cause of animal welfare and campaign for the more humane treatment of sick animals. A 1785 society meeting resolved to "promote the study of Farriery upon rational scientific principles."
Physician James Clark wrote a treatise entitled ''Prevention of Disease'' in which he argued for the professionalization of the veterinary trade, and the establishment of veterinary colleges. This was finally achieved in 1790, through the campaigning of
Granville Penn, who persuaded Frenchman Benoit Vial de St. Bel to accept the professorship of the newly established veterinary college in London.

Veterinary workers
Veterinary physicians

Veterinary care and management are usually led by a veterinary physician (usually called a veterinarian, veterinary surgeon or "vet") who has received their doctor of veterinary medicine degree. This role is the equivalent of a physician or surgeon (medical doctor) in
human medicine, and involves postgraduate study and qualification.
In many countries, the local nomenclature for a vet is a protected term, meaning that people without the prerequisite qualifications and/or registration are not able to use the title, and in many cases, the activities that may be undertaken by a vet (such as animal treatment or surgery) are restricted only to those people who are registered as vet. For instance, in the United Kingdom, as in other jurisdictions, animal treatment may be performed only by registered vets (with a few designated exceptions, such as
paraveterinary workers), calling oneself a vet without being registered or performing any treatment is illegal.
Most vets work in clinical settings, treating animals directly. They may be involved in a general practice, treating animals of all types; may be specialized in a specific group of animals such as
companion animals,

s; or may specialize in a narrow medical discipline such as veterinary surgery, dermatology, cardiology, neurology, laboratory animal medicine, internal medicine, and more.
As healthcare professionals, vets face ethical decisions about the care of their patients. Current debates within the profession include the
veterinary ethics of purely cosmetic procedures on animals, such as
declawing of cats,
docking of tails,
cropping of ears, and
debarking on dogs.
A wide range of surgeries and operations is performed on various types of animals, but not all of them are carried out by vets. In a case in

, for instance, an eye surgeon managed to perform a successful cataract surgery on a
rooster for the first time in the world.
Paraveterinary workers

Paraveterinary workers, including veterinary nurses, veterinary technicians, and veterinary assistants,
either assist vets in their work, or may work within their own scope of practice, depending on skills and qualifications, including in some cases, performing minor surgery.
The role of paraveterinary workers is less homogeneous globally than that of a vet, and qualification levels, and the associated skill mix, vary widely.
Allied professions
A number of professions exist within the scope of veterinary medicine, but may not necessarily be performed by vets or veterinary nurses. This includes those performing roles which are also found in human medicine, such as practitioners dealing with
musculoskeletal disorders, including
osteopaths,
chiropractors, and
physiotherapists.
Some roles are specific to animals, but which have parallels in human society, such as animal grooming and animal massage. Some roles are specific to a species or group of animals, such as farriers, who are involved in the shoeing of horses, and in many cases have a major role to play in ensuring the medical fitness of horses.
Veterinary research

Veterinary research includes prevention, control, diagnosis, and treatment of diseases of animals, and basic biology, welfare, and care of animals. Veterinary research transcends species boundaries and includes the study of spontaneously occurring and experimentally induced models of both human and animal diseases and research at human-animal interfaces, such as food safety, wildlife and ecosystem health,
zoonotic diseases, and public policy. By value the most important Animal Health pharmaceutical supplier worldwide is by far Zoetis (United States).
Clinical veterinary research
As in medicine,
randomized controlled trials also are fundamental in veterinary medicine to establish the effectiveness of a treatment. Clinical veterinary research is far behind human medical research, though, with fewer randomized controlled trials, that have a lower quality and are mostly focused on research animals. Possible improvement consists in creation of networks for inclusion of private veterinary practices in randomized controlled trials. Although the FDA approves drugs for use in humans, the FDA keeps a separate "Green Book", which lists drugs approved specifically for veterinary medicine (about half of which are separately approved for use in humans
No studies exist on the effect of community animal health services on improving household wealth and the health status of low-income farmers.

stem-cell therapy to treat lesions in a wild animal occurred in 2011 in Brazil.
