Abstract: A vehicular pet platform assembly allows a pet to ride safely within a vehicle while protecting the vehicle's interior from damage by the pet. The assembly includes a platform having a top surface, a bottom surface, a front wall, a rear wall, and a pair of lateral walls attached to and extending between the front and rear walls. The platform is configured to support front legs of a pet. A pair of rigid arms is coupled to and extends outwardly from the rear wall. An inner surface of the arms form a receiving slot configured for positioning onto a vehicle door frame such that each of the arms are positioned within a window cavity of the vehicle and against an inside surface of the vehicle door frame.
