Most vets do spays, neuters, bone surgeries, spleen surgery, tumor removals, and intestinal surgeries. Heart surgery and more complicated surgeries are done by specialists that requires more schooling. If you want to be a vet, you have to have REALLY good grades and Vet school is MUCH harder to get into than human medical school.
A veterinary nurse, sometimes referred to as a technician, assists a veterinarian in providing medical treatment to animals. This could be by helping with an examination or preparing a pet for surgery. The assistant may sometimes conduct routine tests or laboratory work.hen a pet owner brings an animal to a veterinary clinic, a veterinary nurse is often one of the first people seen.
