They’re universal, so should fit most estates and 4x4s with a flat back (i.e. no lip or sill at the back, so if you’re lifting a heavy box out of the car you can slide it out without lifting it up over the ledge)
The backseats of the car need to be upright, as the tailgate has bars which need to butt up against the backseat for safety reasons.
The design of the crate means that you would need a soft padded bed (i.e. not a blanket or vetbed) to put over the bars in the back, to ensure maximum comfort for your dog(s). Particularly if you have dobermanns for whom comfort is an absolute priority!
needs to be used in conjunction with the manufacturer’s dog guard behind the back seat.
