Surfcabin Dog Car Door Protector – 20% Larger Design for Sedans, Family Cars and Small SUVS, 2 Packs Thickened Waterproof Door Panel Covers, Protects Doors from Dog Scratching

My dog is also not a great traveler. We use a setup that’s probably more than you need for short trips, so I don’t have a recommendation for an actual seat cover, but I would consider something like these for the back doors. I have a 25 GT as well and wasn’t sure how I’d clean the fabric portion of the doors when my dog inevitably drooled on them, and these have taken care of it. They’re easy to put in and take out, and to wipe down.
