Nissan's X-Trail 4Dogs concept is the perfect car model for dog owners, complete with a pull out shower, a dryer to wash pooches after long walks, a camera in the front so the driver and passenger can keep an eye on their pet, with footage broadcast onto the vehicle's infotainment system. The SUV's boot for pampered pooches also has a slide-away ramp so the family pet can walk into the padded space in comfort. Dogs can settle down into the luxurious bed, help themselves to a drink from the no-spill water bowl or take a snack from the smart dog treat dispenser.
