The number of jobs for veterinarians will increase by 36 percent between 2010 and 2020, according to the U.S. Bureau of Labor Statistics. Vets working with large animals or government will have the best prospects. Veterinary work is very diverse, because some professionals treat small animals, others treat farm or zoo animals and some careers require work in laboratories. The career of a veterinarian requires many physical and personality strengths, depending on the specific position.
