Veterinary medicine and veterinary nursing require skills, oversight, and training, and should be standardized across all 50 states. Very few assistants have the skill, knowledge base, and experience to perform this procedure. Assistants, unlike qualified LVTs do not have the requirement of maintaining a license and continuing education every year. Simply put, they are assistants for a reason, if they want to do procedures, put in the work, get the education, and maintain it.
