(a) A person may not practice veterinary medicine unless a veterinarian-client-patient relationship exists. A veterinarian-client-patient relationship exists if the veterinarian:

(2) possesses sufficient knowledge of the animal to initiate at least a general or preliminary diagnosis of the animal’s medical condition; and
(3) is readily available to provide, or has provided, follow-up medical care in the event of an adverse reaction to, or a failure of, the regimen of therapy provided by the veterinarian.
(b) A veterinarian possesses sufficient knowledge of the animal for purposes of Subsection (a)(2) if the veterinarian has recently seen, or is personally acquainted with, the keeping and care of the animal by:
(1) examining the animal; or
(2) making medically appropriate and timely visits to the premises on which the animal is kept.
