Why a Proper Car Seat Is a Must for Your Big Dog’s Safety

Australia’s 2025 pet census counted over 1.9 million dogs weighing 25 kg or more, yet only 14% of owners regularly restrain them in the car. The myth that “big dogs are fine in the tray” dies hard, but recent NSW Police crash reports reveal unrestrained large breeds become 35-kg projectiles at just 40 km/h. A purpose-built dog car seat for big dogs spreads deceleration forces across the sternum and shoulders—areas strong enough to withstand impact without restricting the airway.

Thread both ISOFIX arms until you hear the dual-click confirmation, then rock the seat; movement should be <25 mm. Attach the top-tether to the vehicle’s designated point, never to a headrest or cargo hook. Final test: grasp the frame and pull—if the entire car rocks, you’re golden.

Securing the harness correctly is mission-critical. Loop the car’s seat belt through the seat’s reinforced D-ring first, then clip the integrated lead to your dog’s chest plate—not the collar—to distribute braking forces across the sternum should you stop suddenly.
