Rachel Schott wants to become a veterinarian because she loves animals and wants to save their lives. To become a veterinarian requires obtaining a Doctor of Veterinary Medicine degree after completing 2-4 years of undergraduate education. Veterinarians work either in private practices treating small animals like dogs and cats indoors, or in mobile clinics treating large animals like horses outdoors. The career outlook for veterinarians is strong with expected job growth and higher earnings potential for those with advanced specializations.
