Security Wire Window Screens for Suburban.?

I know that there is a “full” Wire Divider for the Cargo space of a Suburban, and have seen several of those. But, I would like to have in addition to that, some small (tough) Wire Screens, to install inside on the back Door Windows. I want to lower the windows and open the back glass flap, to allow good air circulation for my Dogs when parked. Anyone have a Link where something like that is available ?
