A veterinarian (North American English) or a veterinary surgeon (British English), often shortened to vet, is a physician for animals and a practitioner of veterinary medicine. The word comes from the Latin veterinae meaning "draught animals." The word "veterinarian" was first used in English by Thomas Browne (1605-1682).
In the United States veterinarians in private practice earn an average salary of $66,590 per year, while those working for the US government average $78,769 per year (2004 Bureau of Labor Statistics data). More recent data from the American Veterinary Medical Association reports median earnings of $77,500-$98,500, for all types of private, public, and corporate veterinarians. Most veterinarians are paid based on production, rather than a straight salary, so earnings can vary based on type of practice, location of practice, and even the season of the year.
Veterinary medicine is the application of medical, diagnostic, and therapeutic principles to companion, domestic, exotic, wildlife, and production animals. Veterinary science is vital to the study and protection of animal production practices, herd health and monitoring the spread of disease. It requires the acquisition and application of scientific knowledge in multiple disciplines and uses technical skills directed at disease prevention in both domestic and wild animals.
