I today took delivery of one of these
E53 X5 Pet Barrier - Cargo Divider
to stop my stupid German shepherd climbing over my seats and eating every one in the car

I slotted he 2 top parts into the roof , and attached the 2 middle bits into the rear seats but how do you stop the bottom flapping around, cos everytime im going to accelerate the dogs going to get a face of pet carrier? does it attach to something else?.
or can some one with a pre facelift take a picture

I needs to buy a parcel shelf for the beast next, it might fit to that . I dunno
