One of the reasons I bought the VX is because I could not get two boxer dogs in my old Porsche. The VX is a sports car with carrying capacity, so to speak. So away went the back seat. And to keep the devils out of the front seats and to protect the interior from scratching I installed a Firstrax 42" collapsible kennel. It's great. It's got it's own waterproof flooring, it zips closed after the dogs jump in and you can kind of look through it when backing. Most important, in short stops they stay protected because of the soft net like sides. Also. it's color coded gray and black to match the interior. Can't say enough good things about this kennel. I tried other cheaper ones, but this is the best. You just lash it down with bungees to the floor hooks and away you go with room to spare for luggage behind the seats. Most of all they love it, it's their dog house on wheels. So there you go.
