Nature of Work: Veterinary medicine is a health profession dedicated to the diagnosis, treatment, and prevention of animal diseases and injuries. Veterinarians use scientific knowledge and decisionmaking processes to enhance the health, welfare, and productivity of animals. They contribute to human as well as animal health by engaging in research, food safety inspection, education, regulatory medicine, and public health. This comprehensive health profession is increasingly important as animal and human populations grow. Most veterinarians in the United States and Canada work in private practices. Specialties within veterinary medicine include research, education, laboratory animal medicine, zoo animal medicine, equine sports medicine, wildlife animal medicine, animalassisted activities, marine biology, and aquatic animal medicine.
