Full Breakdown

Under Section 16, owners are strictly liable when a dog without provocation attacks or injures a person peaceably conducting themselves on public or private property. Section 9 authorizes county animal control to impound dogs running at large. Municipalities may add leash length limits, but the strict liability framework, rabies vaccination requirements, and dangerous dog procedures (Sections 15, 8, 15.1) apply uniformly. State-level rabies vaccination is mandatory for dogs over four months old.
