A veterinarian licensed in Colorado may issue a written waiver as provided in this section exempting an animal from a rabies vaccination order if the veterinarian, in his or her professional opinion, determines the rabies inoculation is contraindicated due to the animal's medical condition. The terms "waiver" and "exemption" as used in this section are interchangeable. A veterinarian may issue a waiver if:
1. The animal to be exempted has a medical condition defined as "a disease, illness, or other pathological state" for which, in the opinion of the exempting veterinarian, a rabies inoculation is contraindicated;
2. A valid veterinary-client-patient relationship, as definied under C.R.S. Section 12-64-103 (15.5), has been established between the veterinarian, owner and animal to be exempted from rabies inoculation;
3. The veterinarian completes and signs the veterinary section of the Exemption from Rabies Vaccination form provided by the department.
4. The animal owner signs the informed consent section of the Exemption from Rabies Vaccination form;
5. The veterinarian maintains the signed exemption as part of the animal's medical record and provides a copy to the owner;
6. The exemption issued is limited to the anticipated duration of the animal's medical condition that precludes inoculation; and
7. The veterinarian provides a copy of the exemption form to the department, the local health department or animal control agency when requested.
C. A waiver may not exceed a period of three years from the date of issuance. If the medical condition persists beyond a three year period and, in the professional opinion of a veterinarian licensed in the State of Colorado the exemption continues to be appropriate, a new waiver may be issued.
D. Upon receiving a complaint regarding the validity of a rabies inoculation exemption, the executive direction or his/her designee(s) may review Exemption from Rabies Vaccination forms and examine the veterinary records pertaining to the medical condition to determine if the medical condition legitimately contraindicates rabies inoculation. If appropriate, the executive director or his/her designee(s) may refer the case to the State Board of Veterinary Medicine.

(b) The State Veterinarian or the Commissioner of Agriculture, or the commissioner's designee, may grant an exemption from vaccination against rabies for a dog or cat if a licensed veterinarian has examined such animal and determined that a rabies vaccination would endanger the animal's life due to disease or other medical considerations. Such exemption may be granted for an individual animal only after the veterinarian has consulted with the State Veterinarian, the Commissioner of Agriculture, or the commissioner's designee, and completed and submitted to the department an application for exemption from rabies vaccination on a form approved by the Department of Agriculture. After approval of such exemption, the department shall issue a rabies vaccination exemption certificate, copies of which shall be provided to the veterinarian, the owner of the dog or cat exempted from rabies vaccination and the animal control officer of the municipality in which the owner of the dog or cat resides. Certification that a dog or cat is exempt from rabies vaccination shall be valid for one year, after which time the animal shall be vaccinated against rabies or the application for exemption shall be renewed.
(c) Any veterinarian aggrieved by a denial of a request for an exemption from rabies vaccination by the State Veterinarian, the Commissioner of Agriculture or the commissioner's designee may appeal such denial as provided in the Uniform Administrative Procedure Act, sections 4-166 to 4-189, inclusive.
