more info on the dog barrier my 6 month old GSP has been driving me nuts lately with his wandering around the cab on drives
I wanted one that doesn't clamp against the headliner, I don't like the scars those leave. This one clamps on the rear headrest. I was afraid it wouldn't be strong enough, but its significantly stronger than I expected. $75 is pricier than I wanted, but it does its job well. My 100lb lab tried sticking his head through this morning, and it held fine.
