Veterinary technicians have been educated in the care and handling of animals, the basic principles of normal and abnormal life processes, and in many laboratory and clinical procedures. In general, veterinary technicians obtain 2-4 years of post-high school education and have an Associate's or Bachelor's degree in veterinary technology. They must pass a credentialing examination and keep up-to-date with continuing education to be considered licensed/registered/certified (the term used varies by state) veterinary technicians.
All veterinary technicians work under the supervision of a licensed veterinarian. While a veterinary technician can assist in performing a wide variety of tasks, they cannot diagnose, prescribe, perform surgery, or engage in any activity prohibited by a state's veterinary practice act.
In a clinical practice setting, such as your local veterinary hospital, veterinary technicians handle many of the same responsibilities that nurses and other professionals perform for physicians – and, like veterinarians, they are trained to work with several species of animals. They are trained to: obtain and record patient case histories; collect specimens and perform laboratory procedures; provide specialized nursing care; prepare animals, instruments, and equipment for surgery; assist in diagnostic, medical, and surgical procedures; expose and develop radiographs (X-rays); advise and educate animal owners; supervise and train practice personnel; and perform dental prophylaxes.
Veterinary assistants support the veterinarian and/or the veterinary technician in their daily tasks. The assistant may be asked to perform kennel work, assist in the restraint and handling of animals, feed and exercise the animals, or spend time on clerical duties.
