Generic Dog Guard for your car (Astley Village PR7)

Walky Dog Guard, designed to fit numerous car models. I used this in a Suzuki S-Cross. It expands to fit the space using slide out poles and it clips on to the rear headrests using the adjustable brackets provided.
Sadly, I don't have the box or instructions and I won't be able to confirm if it fits your vehicle. From the invoice from it back in 2017, it is a 'BICE WalkyGuard no. BCA014'. It can't find an exact match on-line, but this looks pretty close https://www.amazon.co.uk/Walky-Adjustable-Barrier-Automotive-Safety/dp/B003...

One of the tightening fittings has a split in it. I think that this causes one of the arms to rattle slightly. I imagine that this could be fixed with a bit of tape or, if like me, you don't need to use the top extension piece, you could take one of the fittings from there to replace the split one.
