4Knines Back Seat Extender for Dogs - Waterproof Hard Bottom Protector with EZ Door Guard (XL, Black)

Protect Your Car and Your Pup on Every Ride

Discover how the 4Knines Back Seat Extender transforms travel with dogs. The hard bottom creates a stable platform that reduces shifting and helps keep paws and tails from sliding into the footwell. Reinforced panels support dogs of many sizes, providing a balanced ride for both pet and passenger.

The built-in EZ Door Guard adds a layer of protection for door frames, upholstery, and floors. The cover shields against scratches, dirt, and slobber while making it easy for your dog to hop in and out thanks to the patent-pending one-zip access system.

Designed for a Seamless Fit

The XL size is tailored for full-size trucks and large SUVs, offering simple installation and full seatbelt access. It is not recommended for captain chairs or unsupported middle seats, ensuring a secure setup that respects vehicle design.

Built to Endure Real Life

Crafted from heavy-duty, colorfast materials that are free from harmful dyes and metals. Real quilted stitching adds a premium feel and lasting strength for daily use, road trips, or weekend adventures.

Easy Cleanup for a Busy Household

When messes happen, you can remove the rigid panels and hose off, wipe down, or machine wash the cover to keep it looking fresh with minimal effort. This helps maintain a clean interior after muddy paws or wet coats.
