Veterinarians diagnose medical problems, dress wounds, set broken bones, perform surgery, prescribe and administer medicines, and vaccinate animals against diseases. They also advise owners on care and breeding.
Most veterinarians are in private practice.
Some have a general practice, treating all kinds of animals. The majority, however, just treat small companion animals such as dogs, cats, and birds. Others treat both small and larger animals, and some treat only large animals, such as cattle and horses. Veterinarians in companion animal medicine provide services in 20,000 animal hospitals or clinics. Veterinarians for large animals treat and care for cattle, horses, sheep, and swine.
