Hard-Bottom Dog Car Seat Extender - Black

More Space. More Support. Better Road Trips.

Give your dog a flatter, roomier place to rest with this hard-bottom dog car seat extender. Reinforced support panels bridge the footwell gap between the front and rear seats, turning the back seat into a more stable travel platform for everyday drives, longer trips and larger dogs.

Why pet parents love it

• Expanded back-seat space: Covers the open footwell area to create a wider surface for sitting, lying down and stretching out.
• Supports over 250 lb: Reinforced internal panels provide firm support for large dogs or multi-dog households.
• Waterproof protection: Quilted Oxford fabric helps protect the rear seats, seat backs and door areas from muddy paws, fur, moisture and everyday scratches.
• More stable travel: Adjustable headrest straps and an anti-slip base help keep the extender positioned during the journey.
• Breathable mesh panel: Allows airflow and gives your dog a clearer view towards the front of the vehicle.
• Practical storage: Built-in pockets keep leads, wipes and small travel essentials close at hand.
• Easy to pack away: Foldable panels and carrying handles make the extender easier to move and store between trips.

Choose Large for full rear-seat coverage or Small for a single-seat setup that leaves space for a passenger. The Large version includes a removable outer cover for easier routine cleaning, and an optional checked comfort mat is available separately.
