Relating to an attack by a dangerous dog; increasing a criminal penalty.

SB 155 increases penalties for dog attacks causing injury or death when the attack occurs off the owner's property (not on their land, vehicle, or boat). It classifies offenses as a Class B misdemeanor for bodily injury, a third-degree felony for serious injury, or a second-degree felony for death. The bill also creates a new process for municipalities with over 70% of a large county's population to formally determine a dog is "dangerous" after an incident, requiring animal control to investigate and notify owners. This law directly affects dog owners in qualifying municipalities and applies to incidents occurring on or after its September 1, 2025 effective date.
