Dorfman's dog ran into the street in front of Dorfman's home and began chasing cars. Peterson, who was driving a car on the street, swerved to avoid hitting the dog, struck a telephone pole, and was injured. If Peterson asserts a claim against Dorfman, will Peterson prevail? 
Yes, because Dorfman's dog was a cause in fact of Peterson's injury.  Yes, if Dorfman knew his dog had a propensity to chase cars and did not restrain it.  No, because a dog is a domestic animal.  No, unless a statute or ordinance made it unlawful for the owner to allow a dog to be unleashed on a public street.
