Dog car safety guides
Clear, practical advice on travelling safely and legally with your dog — the UK law, how to fit a restraint, and how to choose the right setup for your dog.
Dog car seat belt law: UK Highway Code Rule 57 explained
Yes — under Rule 57 of the UK Highway Code, dogs must be suitably restrained in a moving vehicle so they cannot distract or injure the driver, or hurt themselves in a sudden stop. A seat belt restraint clipped to a harness is the simplest way to comply.

Fit your dog with a well-fitted harness, clip a seat belt restraint into a standard seatbelt socket, attach the other end to the harness's back or chest ring, then adjust the strap so your dog can sit and lie down but can't reach the footwell or a window.
Read the guide →ComparisonDog car harness vs seat belt: which do you need?
They're not either/or — you generally need both. The harness is the padded part your dog wears; the seat belt restraint is the tether that clips the harness into a seatbelt socket. A well-fitted harness plus a strong restraint is the safest, Rule 57-compliant setup.
Read the guide →SafetyAre dog seat belts safe? What owners should know
Yes — used correctly with a well-fitted harness, a dog seat belt keeps your dog from being thrown in a crash and from distracting the driver, which is exactly what Rule 57 requires. Safety depends on attaching to a harness (never a collar), the right strap length, and a strong clip.
Read the guide →How-toHow to measure and fit a dog seat belt
You don't measure the belt to your dog — you fit the harness snugly, then adjust the restraint's length. Put the harness on (two fingers should slip underneath), clip the restraint into the seatbelt socket and the harness ring, then shorten the strap so your dog can sit and lie down but can't reach the footwell.
Read the guide →Small dogsSecuring a small dog or puppy in the car
Small dogs and puppies must be restrained just like large dogs — Rule 57 applies to every size. Use a snug small-dog harness and a seat belt restraint set short so they can't slip free or reach the footwell. Our belt adjusts down to 45cm; never clip to a collar.
Read the guide →Large dogsSecuring a large or strong dog in the car
Large, strong dogs put far more force on a restraint in a crash, so use a heavy-duty harness and a strong restraint — or, for the biggest breeds, a crash-tested crate or the boot behind a dog guard. Our belt extends to 78cm with heavy-duty webbing and a steel swivel clip.
Read the guide →Buying guideHeavy-duty dog seat belts: what to look for
A heavy-duty dog seat belt has strong, wide webbing, a solid metal swivel clip (not plastic), secure bar-tack stitching, and adjustable length. Avoid thin straps and plastic clips. "Universal" simply means it fits any standard seatbelt socket.
Read the guide →SafetyCollar vs harness for car safety: why it matters
Never attach a car seat belt to a collar. In a crash or hard stop the force concentrates on your dog's neck and can cause serious injury. Always attach the restraint to a well-fitted harness, which spreads the force across the chest and shoulders.
Read the guide →Size guideThe best dog car restraint by size and breed
The right restraint depends on your dog's size and strength, not the exact breed. Small breeds need a snug harness and a short strap; large, powerful breeds need heavy-duty gear or a crate. One adjustable seat belt (45–78cm) plus the right harness covers most dogs.
Read the guide →Crash safetyWhat happens to a dog in a car crash without a restraint?
In a crash an unrestrained dog becomes a projectile. At around 30mph a dog can be thrown forward with a force often cited as roughly 30 times its body weight — enough to seriously injure or kill the dog and to hurt other people in the car. A restraint keeps the dog anchored and cuts that risk.

For a long drive, restrain your dog with a harness and seat belt, stop roughly every two hours for a toilet and stretch break, bring water and a bowl, never leave them in a hot car, and pack their lead, poo bags and any medication. Plan dog-friendly stops before you set off.
Read the guide →TravelBoot vs back seat: where should your dog travel?
Both can be safe as long as your dog is properly contained. A back seat suits most dogs with a harness and seat belt restraint; the boot suits larger dogs behind a dog guard or in a crash-tested crate. Never let a dog travel loose, and avoid the front seat where an airbag can injure them.

Ease car sickness and anxiety by building up short trips gradually, travelling on a fairly empty stomach, keeping the car cool and airy, and restraining your dog securely so they feel stable. If sickness or fear persists, ask your vet — effective anti-sickness and calming options exist.

Holiday travel means busier roads and longer drives, so restrain your dog with a harness and seat belt, plan regular breaks, keep festive hazards like chocolate and raisins out of reach, and pack for cold weather. Never leave your dog alone in the car.
