Some product like this is a must! I have an Aussie terrier and she sheds like crazy. You’ll thank yourself for getting something like this to keep the volt clean. The trunk/back of the seats are impossible to clean from dog hairs. The hammock is easily removable/installable.Get a "pet hammock" for the rear seat
(Link for example, I am not endorsing this specific product)
They are amazingly helpful if you are gonna travel with your fur-pal but make sure you get a good one that is waterproof and it'll last a lot longer.
