Thanks Richard, but don`t want put the dog in a cage, as she likes to move about and look out of the windows, that`s why I thought the divider would be a good idea, but not at that price! I`ll keep looking on eBay though not too hopeful.
As the cages are different sizes you could get one that would be equvalent to half the boot space and put it sideways
Or if I remember correctly there were several manufactures of dog guards (when I last went to Crufts)other than the Ford bespoke item that may be able to supply. Have you tried putting dog guard into google and seeing what comes out?
