Exempts livestock guardian dogs and herding dogs from license fees

S 1632 exempts livestock guardian dogs (used to protect livestock from predators) and herding dogs (trained to manage livestock) from municipal dog licensing fees. The bill amends state law to require municipalities to waive these fees for qualifying dogs and mark their licenses with "Livestock Guardian Dog" or "Herding Dog." It directly affects livestock owners and ranchers who use these working dogs. The law takes immediate effect upon enactment.
