Vet Techs

Veterinary Technicians work closely with the doctors to provide your animal with the best care possible. Educated and skilled, the technicians (and technician assistants) medicate the hospitalized patients, obtain blood samples for testing, perform laboratory blood tests in house and prepare samples to go to outside laboratories.

They also assist the doctors in surgery, including monitoring anesthesia, performing dental scaling and polishing, preparing medications to go home with patients, taking radiographs (including dental). Other responsibilities include care such as nail trims, cleaning ears, anal gland expressions and ear flushes, etc.)
