so I have a dog and typically have the rear seats folded down flat so the dog can stand up in the back of the vehicle. The problem with this is the fabric that is on the back of the rear seats and the trunk really holds dog hair and it gets embedded very easily. I am looking for some kind of protector that I can lay in the back of the vehicle with the rear seats folded down so it covers that entire trunk/rear seat area where the dog stands and lays. The weathertech stuff is custom but only for the trunk and I'm not sure how grippy it is. I don't want my dog sliding around back there. Any suggestions for material or product that is suitable to be latest over the entire back cargo area with rear seats folded down that isn't slippery?
