When i take the RSPCA dogs for a walk, they usually get my back seat in a right state, fur, mood, chewed seatbelts I currently have a blanket on there, which works fine for the small dogs and puppies, but when i have some of the big dogs in there, the blanket usually end up falling down and on the floor. Anyone got any ideas? Or anywhere i can get a cheap plastic cover for the back seat. I have a Ford KA. I need it to be easily removable and easy to put on, for when i have people in the car.
