A veterinary technician is trained to assist veterinarians in caring for pets. These professionals perform many of the same tasks that a nurse would for a doctor. Veterinary technicians have received training, either in accredited programs or on the job. Responsibilities vary among clinics, but the basic duties remain the same. For instance, technicians collect patient samples, perform lab tests, assist during patient exams and dental cleanings, and take x-rays. Senior techs also train and mentor other staff members. Some technicians work in research facilities or for manufacturers.
