A veterinary-client-patient relationship serves as the basis for interaction between veterinarians, their clients, and their patients. A veterinary-client-patient relationship exists when all of the following conditions have been met:

(A) A veterinarian assumes responsibility for making clinical judgments regarding the health of a patient and the need for medical treatment, medical services, or both for the patient, and the client has agreed to follow the veterinarian’s instructions regarding the patient.

(B) The veterinarian has sufficient knowledge of the patient to initiate at least a general or preliminary diagnosis of the medical condition of the patient. In order to demonstrate that the veterinarian has sufficient knowledge, the veterinarian shall have seen the patient recently and also shall be acquainted personally with the keeping and care of the patient either by examining the patient or by making medically appropriate and timely visits to the premises where the patient is kept.

(C) The veterinarian is readily available for a follow-up evaluation, or has arranged for emergency coverage, in the event the patient suffers adverse reactions to the treatment regimen or the treatment regimen fails.
