About this item
- Spacious & Stable for All Dogs – This backseat extender for dogs (52.4’’ long, 24.8’’ wide, and 21.7’’ high) feature a hard bottom that expands space by 40%, supports up to 400 lbs, and includes firm inserts for a large stable base–ideal for multiple dogs or older, anxious pups. Plus, this 2025 version features a new, expansive storage pouch on the back of the driver’s seat for maximum storage.
- Compatible with the Following Vehicles: Tesla Model 3, Y, and S. Toyota RAV4, 4Runner, Highlander, and Tacoma. Honda Accord, Civic, and CR-V. Jeep Wrangler and Cherokee. Chevy Equinox. Nissan Rogue. Subaru Forester and Outback. Mazda CX-5. Hyundai Tucson. Audi A1. Cadillac XT6. Chrysler 200. Dodge Charger. Jaguar F-Pace. Maserati Levante, and other cars, mid-size SUVs, and mid-size trucks.
- Not for Other Models - The Standard size is suited only for cars, mid-size SUVs, and mid-size trucks only. If your vehicle isn’t listed above, this Standard Seat Extender will not fit. For full-size trucks and full-size SUVs, select the XL size to ensure the proper fit. Will not work with captain’s chairs or rear-hinged, backward-opening truck doors. Does not work in 3rd row.
- Extends Seat for Cars, Suvs & Small Trucks – Trimmed for cars, SUVs and mid-size trucks, the new 2025 backseat dog cover and extender uses a hard-board core and waterproof Oxford quilt. Unfold, secure the corner anchor straps, fasten each headrest strap, and you’ve bridged the seat gap for pets or cargo. The washable surface stops grocery bags tipping, lets pups sprawl, and folds up for quick stow when passengers need legroom.
- Protected Door Panels – Shield doors easily with our dog seat cover for back seat with patented door panel protection (U.S. Patent No. 12,221,024) that velcros to window inserts that slide into the window seal. Blocking scratches, drool, and muddy paw prints mile after mile.
- Easy Clean & Waterproof – Triple‑layer back seat cover for dogs repels water, mud, and fur across the backseat interiors. Wipe clean on the go, or machine‑wash on gentle for heavy messes and hang‑dry to keep your back seat fresh and spotless. Comes with a heavy-duty waterproof travel bag for tidy, grab-and-go storage.
- Easy Install & Secure Design – Transport your pet safely with this pet seat cover for back seat with built-in anchors, seat belt zippers compatible with child seat anchors (LATCH), a non-slip underside, and a giant zippable mesh that allows for maximum airflow. The secure design keeps pets steady in transit while you focus on the drive.
