In the United States, becoming a veterinarian requires 4 years of veterinary medical school often after 4-5 years of college or university to earn a bachelor's degree. There are some veterinary schools that will admit an application after only 2-3 years of undergraduate, though. All applicants must complete all of the vet school prerequisite classes--get very good grade and GRE test scores-- and have good hands-on experience working with animals in a clinical or research setting. When you graduate from an American veterinary school you earn a Doctorate of Veterinary Medicine (DVM) or Veterinary Medical Doctorate (VMD).
Veterinary schools in other parts of the world are a little differnt. In other countries (Canada, UK Australia etc), veterinary school training starts right after secondary school/high school. Student there attend veterinary school for 5 year and graduate with a BVetSci (Bachelors in Veterinary Science). While Americans can (and do) attend these schools, Americans do often after obtaining a Bachelor's in Science at a state-side 4 yr college or university before attending these international schools.
