Some states have a law that is commonly known as the one-bite rule. It means that if a dog has never bitten or been aggressive toward another person in the past, they would assume that the owner of the dog would be unaware that their dog could cause harm to another person. So in some states they don’t hold the dog owner liable if it is the first time that their dog has bitten someone. However, this doesn’t apply in every state. Therefore, you need to contact a personal injury lawyer to discuss the laws that govern your potential claim for a dog bite.
