The hammock really is the best option for dogs. But if you need a traditional seat cover, I would highly recommend CoverKing. Maybe not neoprene though, I would do a canvas or similar material.
If you have the need for passengers, I have the Aries Seat Defenders. Also have them on the front seats. Great for grandkid spills! They have rubber material underneath, so don't slip around.
after a full year, i am really happy with the Carhart seat covers. they fit nice, are tough, and the dog hair vacuums off better than any seat cover i have tried. my yellow lab/golden retriever mix never stops shedding. They were pricey, but i feel they have been worth it. my FordPass points helped take out some of the sting.
