There are three words that can distinguish a Registered Veterinary Technician from a veterinarian:
Diagnosing. Prescribing. Performing.
The veterinarian must diagnose the patient, prescribe the medication, and/or perform surgery. Even in these three scenarios, a vet tech is the veterinarian’s assistant. Otherwise, an RVT must contain much of the same knowledge a vet does. The doctor will diagnose the patient and prescribe medications, and the technician will carry out the doctor’s desired treatment(s). This is an extremely important facet in itself, as the technicians are available to assist the doctor’s and take care of them as well as the patients.
