I have two large hairy dogs. I use three different items, all go in the washing machine after use , then a ten minute vac job. #1, take an old fitted sheet, queen, cut two slots where the seat belts come through. The elastic, and the stiff buckle ends through the slots keep it in place, the long side of the sheet goes over the headrests, and the other side under the front of the rear folding seat, this keeps the dirt off the fabric. #2, get a Mexican blanket, add two, 2" wide nylon webbing strap/ hoops, to hang over the headrests, used little spring clamps to get the right length, secured with large grommets and hot glue around the blanket and web. I had to fold the top edge of the blanket over about 3 " with hot glue to make if stronger, so the grommets don't pull out. Cut two slots the same place as the sheet for the seat belts. Reinforce the slots, with webbing and glue so it doesn't fray. #3,use two large towels on the floor. takes an hour or so to make. this keeps the hair stuck to the Mexican blanket an towels, the sheet catches the fine dirt. It all fits in the washing machine one load. used to take 45 min., vac job, now takes 10 min. Not the prettiest but works great , the sheet and towels fit under the seat, the blanket is folded up and left on the floor.
