The Mégane II Owners' Club

Having just acquired a car-loving Labrador, I need to find a dog guard that will fit in my Megane CC.Obviously because this is a 2 door car, I can't use any of the proprietary guards on the market. It would have to move with the seat tilting forward to allow the dog to get in and so would probably have to clip somehow on the headrests but would therefore have to be in two sections, one for each headrest. Has anybody successfully solved this problem? (and don't say get rid of the dog!). I don't want to change the car for a hatchback or estate as I really enjoy driving this car.
