Planning a trip with your dog and wondering if the boot is the best place? Done right, it can be safe and calm for them, and less distracting for you. UK drivers also need to follow Highway Code Rule 57, which says dogs must be suitably restrained so they can’t distract you or be injured if you stop quickly. Here’s a simple set-up you can copy before your next drive.
Key Takeaway:
-
A dog can travel safely in the boot if it is open to the cabin, well-ventilated, and properly set up.
-
UK drivers must follow Highway Code Rule 57, which requires dogs to be restrained so they don’t distract the driver or get injured.
-
Estate cars, hatchbacks, and SUVs are usually suitable because their boots are part of the main cabin space.
-
A sealed saloon boot with poor airflow is not a safe place for a dog to travel.
-
If your dog seems cramped, anxious, or forced into an awkward position, the back seat may be the safer option.
-
The main goal of restraint is to stop your dog becoming a hazard during sudden braking or sharp turns.
-
A properly secured, crash-tested crate is often the safest and most controlled solution for boot travel.
-
For larger dogs, a strong dog guard combined with a short harness tether can work well when fitted correctly.
-
Careful loading, using leads, ramps, and non-slip mats, helps prevent injuries and sudden escapes.
-
Before driving off, always check airflow, temperature, restraint security, and that nothing can slide into your dog.
Is it safe for a dog to ride in the boot in the UK?
A boot can be a safe choice when it’s part of the cabin, with good airflow and a flat load space, such as in many estates, hatchbacks, and SUVs. It keeps your dog away from pedals and laps, which helps you focus, and it reduces injury risk in a sudden stop.
It’s not a good option if the boot is sealed off from the cabin (typical saloon boot), or if ventilation is poor. Rule 57 is clear that restraint matters, see the wording on Highway Code Rule 57. If an unrestrained dog causes a distraction, it can lead to a careless driving allegation and possible insurance issues.
Boot types that work best (estate, hatchback, SUV)
Look for an open boot area behind the rear seats, not a separate compartment. You want fresh air, stable temperature, and the ability to check on your dog at a glance (even via the mirror). If you can’t see them at all, treat that as a warning sign.
When to choose the back seat instead
Use the back seat for small dogs that slide about, dogs that get anxious and need you close, or cars with short, sloped boots. If the boot forces your dog to crouch, twist, or lie against luggage, the back seat is usually kinder and safer.
The safest ways to restrain a dog in the boot
Your aim is simple: stop your dog becoming a moving object in a hard brake, and stop them climbing into the cabin. As a default, choose either a secured crate in the boot, or a dog guard plus a harness attached to proper anchor points.
Whatever you pick, check it fits your car and your dog’s size. Then practise with short, quiet trips so your dog learns the routine without stress.
Crash-tested crate or travel cage (best all-round option)
A crate works well for many dogs because it creates a clear boundary. Size it so your dog can stand, lie down, and turn around. Secure it so it can’t slide, using the car’s tie-down points where possible. Add a grippy mat or bedding so paws don’t skid, and keep vents clear. If you’re comparing designs, it helps to understand what “crash-tested” means, see examples on MIMsafe’s crash-tested dog crate guide.
Dog guard plus a boot harness (good for bigger dogs)
A dog guard stops your dog coming over the rear seats, but it doesn’t stop them being thrown around in the boot. Pair it with a harness or tether clipped to an anchor point, set short enough to prevent a run-up. Check the guard fixings often, and make sure there are no sharp edges near where your dog leans.
How to load your dog into the boot safely, step by step
Loading is where most slips and escapes happen. Keep it calm, keep the car still, and don’t rush. For older dogs or heavy breeds, a ramp is safer than repeated lifting.
Heat builds fast in cars, even in mild weather. Never leave your dog in a parked car, and plan water and breaks on longer trips.
A simple loading routine that prevents slips and escapes
- Park securely, handbrake on, engine off if safe to do so.
- Open the boot, then clip the lead on before your dog jumps.
- Guide them up (lift with a straight back, or use a ramp).
- Settle them into the crate or behind the guard.
- Secure the restraint, then close the boot and check the latch.
A non-slip mat helps, and loose items should come out or be strapped down.
Comfort and safety checks before you drive off
- Restraint is tight, and nothing can slide into your dog.
- Your dog can lie down and breathe easily.
- Airflow is OK, and the boot isn’t overheating.
- Windows and doors are secure, and luggage can’t shift forward.
When planning safe travel for your dog, it’s also important to consider how the right seating choice can reduce risks on the road.

Conclusion
The boot can be a safe place for a dog when the car layout suits it and the set-up is secure. Follow Rule 57, restrain your dog with a crate or a guard plus harness, and lock down anything that could move. Keep the boot cool, clear, and well-ventilated. Before a long journey, do a short test drive and see how your dog settles.

A dog can travel safely in the boot on long trips if there is good ventilation, enough space to lie down, and regular breaks for water and rest.
3. Which car boots are safest for dogs?
Open boots in estate cars, hatchbacks, and SUVs are safest because they allow airflow and temperature control from the cabin.
4. Is a saloon car boot safe for dogs?
No, a typical saloon boot is not safe because it is sealed off from the cabin and usually has poor ventilation.
5. Do dogs need to be restrained in the boot?
Yes, dogs must always be restrained to prevent injury during sudden braking and to stop them moving into the cabin.
6. What is the safest way to restrain a dog in the boot?
A crash-tested crate that is securely fixed is generally the safest option for most dogs.
7. Can I use a dog guard without a harness?
A dog guard alone is not enough; it should be combined with a harness or tether to stop the dog being thrown around in the boot.
8. Is a crate better than a harness for boot travel?
For many dogs, a crate provides better protection and reduces stress by creating a secure and familiar space.
9. How much space does a dog need in the boot?
Your dog should be able to stand up, lie down comfortably, and turn around without restriction.

Always secure the lead first, use a ramp or proper lifting technique, and avoid rushing to prevent slips or escapes.
13. Is it safe to leave a dog in the boot while parked?
No, dogs should never be left in a parked car, as temperatures can rise quickly even in mild weather.

The back seat is better for small, anxious dogs or when the boot space is too short, sloped, or uncomfortable.
15. Should I test the set-up before a long trip?
Yes, a short test drive helps you check comfort, restraint security, and how well your dog settles before a longer journey.
