Thanks. Our pug and retriever/shepherd mix are both shedding machines. The pug sometimes rides in my Tacoma pickup (standard cab) and you pretty much have to vacuum the seat every time, no matter how short the ride. Their usual ride is my wife's Cherokee, which is thoroughly coated--it takes a couple hours when I detail it to get rid of hair and it's back to coated again within a week. Doesn't help that it's light-colored hair on a dark interior. We're looking for a sedan for her now. That back seat protector would work, I think, for the mutt, but the pug is a different matter. It goes where it wants when it wants in a vehicle, or anywhere else, for that matter.
I have this: http://www.orvis.com/store/product.aspx?pf_id=9R92 and it worked decently enough for us in a 4Runner, MDX, and Suburban. When my last dog passed away, I stashed it in my parent's attic. If they haven't thrown it out yet, I'd be happy to pass it along for just the cost of shipping, as another dog is not in the cards for us for at least another 5 years when the lady finishes residency.
