The state-level rules every owner and walker in Vermont should know. Local leash lengths, licensing and off-leash rules are set by each city — find those on the city pages below.
Vermont is a one-bite / negligence state — its Supreme Court was asked to adopt strict liability and declined, leaving that to the Legislature (a reform proposed but not enacted; confirm current status).
Vermont is a one-bite / negligence state — one of the more owner-favorable regimes. Liability requires the owner knew or should have known the dog had a vicious propensity (Hillier v. Noble; Davis v. Bedell) — a prior bite is not required, as lunging, snapping, or a known fierce disposition can suffice. In Martin v. Christman (2014), the Vermont Supreme Court was asked to adopt strict liability but declined, saying any change should come from the Legislature. (Reform bills such as H.56 have been proposed but not enacted; confirm the current status before relying on it, as this is a changeable area.) A negligence route also applies — an owner who failed to use reasonable care with an unleashed or improperly secured dog, including for non-bite injuries — and a local leash or at-large violation is negligence per se.
Vermont applies modified comparative fault, with trespass and provocation defenses; one town (Montgomery) has a pit-bull ordinance. The personal-injury limit is three years.
