Rhode Island General Laws Title 4. Animals and Animal Husbandry § 4-13-1.1. Towns of Portsmouth, West Warwick, and Middletown and city of Woonsocket--Vicious dog ordinance

(a) Notwithstanding any other provisions of this section or the general laws to the contrary, the town councils of the towns of Portsmouth, West Warwick and Middletown may, by ordinance, provide that the owner or keeper of any dog that assaults any person shall be fined an amount not less than one hundred dollars ($100) nor more than two hundred dollars ($200) to be used as that city or town council may prescribe. However, this fine shall not be imposed unless the officer responsible for enforcement of that ordinance has conducted an investigation of the assault and has certified that the dog was off the property of its owner or keeper and at large at the time the assault occurred or that the assault resulted from the negligence of the owner or keeper.

(b) In the city of Woonsocket an owner shall not be declared negligent if an injury or damage is sustained by a person who, at the time that injury or damage was sustained, was committing a trespass or other tort upon premises occupied by the owner or keeper of the dog, or was teasing, tormenting, provoking, abusing or assaulting the dog or was committing or attempting to commit a crime.
