Ditch the hammock!
Finally found a perfect solution for my Flat-coated Retriever why insists on sitting up on road trips to see if she's maybe hopefully going to "camp", which she loves. Problem was, she's a big ol' girl with (God forgive me) a little bit of junk in the trunk, so sitting up in the first row back seat area of our '03 Honda Odyssey was hard on her and laying down no better. This bed solved both probs brilliantly. Perfect fit, too!
This thing is awesome. I was skeptical at first because of the non-total seat coverage/height and the material but my dog loves riding along now after always previously hating car rides. If you plan to regularly have people riding in your backseat this is a must own because it installs/uninstalls in seconds and leaves your back seat in beautiful condition, thereby not forcing the backseat passengers to ruin their outfits by sitting in a seat full of doggy fur.
