Pet Barrier Recommendations

[TiminIndy]

I'm looking to buy a pet barrier for my E53, so I thought I would see if anyone had any recommendations. I want to be able to fold down the rear seats and prevent my German Shepherd from trying to get into the front seat.

There's a few on Amazon I have looked at that looks like they would work. Looks like I would need to open the moon roof cover and push the bars up to the glass, then just not open the glass when using this:

I am also looking at several protective covers that would cover the entire rear area. I need to get some measurements, because it looks like a lot of them won't be long enough to cover the area with the back seats folded down.
