Easy Maintenance: Simply wipe clean with a damp cloth or remove and machine wash when needed. Dries quickly and stays looking fresh.
Trusted Quality: Designed by dog lovers who understand what large breeds need. Rigorously tested for durability, safety, and real-world performance.

Frequently Asked Questions
Will this fit my car?
Yes! Our seat extender features a universal design with adjustable straps that fit most cars, SUVs, and estates. It attaches securely to headrests and seat anchors, accommodating various back seat widths and configurations. If you have a particularly narrow or wide vehicle, please check your back seat dimensions before ordering.
Is it suitable for my large breed dog?
Absolutely. This extender is specifically engineered for dogs up to 120 lbs (54 kg), making it ideal for Labradors, German Shepherds, Golden Retrievers, Rottweilers, and similar large breeds. The reinforced construction and sturdy platform provide ample support and space for your dog to travel comfortably.
How do I install it?
Installation is quick and simple—no tools required. Simply loop the adjustable straps around your headrests and secure the anchors to your seat fixtures. The entire process takes under 2 minutes, and the extender stays firmly in place once installed. It's just as easy to remove when needed.
Is it really waterproof?
Yes. The premium Oxford fabric is fully waterproof and protects your car seats from wet paws, spills, mud, and accidents. It's perfect for rainy walks, beach trips, or any adventure where your dog might get wet or dirty. Simply wipe clean or machine wash to keep it fresh.
Can I still use seatbelts with this installed?
Yes, the design allows access to seatbelt buckles, so you can still secure passengers or use a dog seatbelt harness for added safety. The extender complements your existing safety measures rather than replacing them.
How do I clean it?
Maintenance is effortless. For light cleaning, simply wipe down with a damp cloth. For deeper cleaning, remove the extender and pop it in the washing machine on a gentle cycle. It air-dries quickly and maintains its shape and durability wash after wash.
Will my dog actually use it?
Most dogs love it! The flat, stable platform eliminates the uncomfortable gap between seats, giving your dog a secure space to lie down or sit. The non-slip base and padded surface provide comfort, and many dogs settle down more quickly and calmly once they're on the extender.
What can I store in the pockets?
The integrated storage pockets are perfect for leads, poo bags, treats, collapsible water bowls, toys, grooming wipes, and any other dog travel essentials. They're designed to keep everything organised and within easy reach, so you're always prepared on the go.
Is it safe for long journeys?
Yes. The secure anchor system keeps the extender firmly in place, even during braking, cornering, or motorway driving. Combined with a dog seatbelt or harness, it provides a safe, stable environment for your dog on journeys of any length.
Can I use it with multiple dogs?
Yes, as long as the combined weight doesn't exceed 120 lbs (54 kg) and your back seat is wide enough to accommodate them comfortably. Many customers use it successfully with two medium-to-large dogs travelling together.
