Overview

Wyoming Statutes § 35-4-107 and related Department of Agriculture rules require rabies vaccination for dogs and cats. Vaccination must be administered by a licensed veterinarian, and bites must be reported to local authorities.

Skunk rabies is common in Wyoming, particularly in rural and agricultural areas. Bat encounters are the leading cause of human rabies exposure risk. Keeping pets vaccinated reduces the risk of transmission to humans.

Vaccination Requirements

Dogs and cats must receive their initial rabies vaccine by 4 months of age. Boosters follow the licensed interval for the product administered (1-year or 3-year).

Vaccination certificates issued by the veterinarian serve as proof of compliance. Wyoming municipalities may require proof of vaccination for dog licensing.

Dogs and cats must be vaccinated by a licensed veterinarian.
First dose by 4 months of age.
Retain certificates and present on request.

Bite Reporting and Quarantine

Bites must be reported to the county health officer or animal control. The biting animal is subject to a 10-day observation period to detect signs of rabies.

For skunk, bat, or other wildlife exposures, contact the Wyoming Department of Health immediately. Post-exposure prophylaxis decisions are made based on the animal species and exposure circumstances.
