The law does not say it's okay for someone's dog to foul your car, so you objection is irrelevant. The law requires that service animals be housebroken. Should a service dog foul your car then do the same thing you would do if your passenger, or the passenger's infant, fouled the car. Edit: A summary of the ADA requirements is at http://www.ada.gov/service_animals_2010.htm http://www.ada.gov/service_animals_2010.htm . > A person with a disability cannot be asked to remove his service animal from the premises unless: (1) the dog is out of control and the handler does not take effective action to control it or (2) the dog is not housebroken. > If a business such as a hotel normally charges guests for damage that they cause, a customer with a disability may also be charged for damage caused by himself or his service animal.
