adjustable dog guard wanted

[frankie4748]

Does anyone know where I can buy (secondhand preferably) an adjustable dog guard for my Skoda Octavia estate please? We have two german Sheps, one of whom scrambles over from the "boot", across the rear seats and into the driver's seat occasionally, leaving a trail of saliva over the steering wheel!!
How he does it we don't know, as all the headrests are in place, leaving only a small space for his very large frame to squeeze through. We have a dog guard in the UK, so don't want to spend a lot on a new one here. I know - I can hear you saying "why didn't you bring it with you then?". I can only say, the dog never climbed over in the UK, must be something about Albox!!!!
