Dog guard OR car divider (KT14)

Dog guard or adjustable divider to fit a small hatchback/estate. Skoda Roomster/Fabia.

I am looking for something that will divide the back of my car loading space, to keep a dog in the rear.

I am helping a friend who has lots of dogs to walk, but they have injured their foot, last week. I have some dogs that need to be isolated, because they are not well socialized and need to be separated.

Thanks for your consideration. :-)
