1. Except as provided under subsection 2, a veterinary prescription drug must be dispensed, used, or prescribed within the context of a veterinarian-client-patient relationship.

The drug is prescribed by a veterinarian or by a foreign practitioner who has established a veterinarian-client-patient relationship; b. The prescribing veterinarian or foreign practitioner has an inadequate supply of the drug, failure to dispense the drug would interrupt a therapeutic regimen, or failure to dispense the drug would cause an animal to suffer; c. The dispensing veterinarian verifies the prescription with the prescribing veterinarian or foreign practitioner; and d. The dispensing veterinarian is not presumptively aware of any disciplinary action against the prescribing veterinarian or foreign practitioner.
