defining and regulating livestock guardian dogs.

HB 1133 defines "livestock guardian dogs" (LGDs) as dogs specifically trained to protect livestock from predators while kept primarily with livestock. It requires owners to register LGDs annually with town or city clerks, provide a signed statement confirming their purpose, and may need to verify livestock ownership. The bill allows LGDs to run at large under specific conditions (minimum land requirements, registration, training, and no nuisance behavior) but prohibits them from trespassing. It establishes penalties for excessive barking (e.g., $150 for second violation, $500 for third), defining excessive barking as lasting over 10 minutes without predator activity or interfering with neighbors. This directly affects farmers using LGDs, modifying nuisance laws to accommodate their operational needs while protecting neighbors from disruptions.
