Veterinary medicine deals with the prevention, diagnosis, and treatment of diseases and injuries in animals. It covers all animal species, both domestic and wild. Historically, the first veterinarians focused on caring for horses due to their economic importance. The first veterinary college was established in Lyon, France in 1762, and others soon opened in Europe and the United States, initially concentrating on horse care. Today, veterinary schools award degrees like the DVM and train students to care for both livestock and companion animals.
