The Car Cube® is a rear-seat dog seat, not a proven crash-protection system. Its maker says to secure your dog with a separate harness attached to the seat-belt fixing, but the product page reviewed does not establish that the Cube itself has been crash-tested. For collision protection, independent veterinary guidance recommends a crash-tested harness, seat belt, or suitable secured travel crate.
What the Car Cube is—and what its specifications tell you
Big Dog Bed Company describes the Car Cube as a waterproof, fleece-lined seat for one rear passenger seat, leaving two rear seats available. It is intended for medium to smaller large dogs; the maker gives Labradors, Vizslas, collies, and cockerpoos as examples. Its listed dimensions are a 52 cm square base, 48 cm sides, and a 62 cm square top. The cover is machine washable, and the product has removable stiffening rods, adjustable straps, quick fasteners, and a drop-down access flap. These are maker specifications, not independent safety findings. Big Dog Bed Company’s Car Cube product page.
The maker presents it as an option for dogs that dislike travelling in the boot, older dogs that are harder to lift, or owners who want to keep boot space free. Those are intended-use claims; they do not establish that the seat prevents anxiety or motion sickness, or protects a dog in a collision.
Does the Car Cube keep a dog safe in a car?
The maker’s product page does not establish that the Car Cube itself has been crash-tested or certified. Its instructions require a harness attached to the seat-belt fixing, but that instruction is not evidence that the complete Cube-and-harness arrangement has demonstrated crash performance. The maker does not include a harness and recommends seeking a crash-tested brand if you need one. Car Cube product page.

Cornell University College of Veterinary Medicine’s Riney Canine Health Center states: “The safest way for your dog to travel is in a crash-tested harness, seat belt, or travel crate.” This is general travel guidance, not an evaluation or endorsement of the Car Cube. If a crash-tested option is unavailable, Cornell advises securing a carrier on the floor behind either front seat. Cornell’s car and pet travel guidance.

Choosing and using a restraint
Do not assume a harness or tether is crash-tested because it looks sturdy or is sold for car travel. Check the exact model’s independent crash-test status, whether it fits your dog, how it attaches to the vehicle, and whether its instructions can be followed in your car and seating position. Cornell names crash-tested harnesses, seat belts, and travel crates as safer travel options; CDC guidance also describes a dog riding in the back seat in a harness attached to the seat buckle, or a crate secured against sliding. Cornell; CDC Pet Travel Safety.
A crate should be ventilated and large enough for the dog to stand, sit, lie down, and turn around, according to the CDC. If you use the Car Cube, treat its containment and comfort features separately from the crash-protection evidence for a restraint: the seller’s page does not establish the Cube’s crash performance.

Introduce the setup gradually
Let your dog get used to the seat, harness, and car in short, calm sessions before relying on them for a longer journey. The CDC recommends gradual acclimation through short drives; VCA also describes gradually getting dogs accustomed to confinement and travel triggers. CDC Pet Travel Safety; VCA guidance on travelling with dogs.

Plan breaks and prevent common hazards
- On longer trips, stop regularly for bathroom breaks and a chance to stretch, as the CDC advises.
- Keep your dog restrained rather than loose in the vehicle. Cornell warns against loose dogs and dogs riding with their heads outside windows; VCA notes the risks of driver interference and escape through an open door or malfunctioning window. Cornell; VCA.
- Never leave your dog alone in a parked car. Cornell and the CDC both give this warning. Cornell; CDC.
What to check before setting off
- The Cube is positioned and its base rests fully on the rear seat.
- The retaining straps, harness, and seat-belt connection are fitted according to the relevant makers’ instructions.
- Your chosen restraint is appropriate for your dog and vehicle; do not treat the Cube’s features or a generic tether as proof of crash testing.
- Your dog has had a gradual introduction to the setup, and longer-trip breaks are planned.
