If you have ever tried driving with a dog loose in the back of your car, you know the score. Paws on the centre console. Nose smears across every window. A sudden lunge toward a passing squirrel that nearly sends you into the hedge. It is stressful for you and genuinely dangerous for them. At dogfoodsuk.com we spend a lot of time writing about what goes into your dog’s bowl, but what happens when you need to get them somewhere matters too. The right dog car travel accessories turn a chaotic drive into something you both can actually enjoy.
Whether you are heading down to Cornwall for a week, nipping to the vet, or driving to your favourite walking spot, having your dog properly set up in the car makes a real difference. I have driven thousands of miles with my own dogs and tried more accessories than I care to admit. Some of them were genuinely useful. Others were a waste of money. This guide covers the kit that actually works, what the law says about dogs in cars, and how to keep your dog comfortable on longer UK road trips.
Why dog car accessories actually matter
A lot of people think car accessories for dogs are a nice-to-have. A seat cover because the upholstery is getting muddy. A travel bowl because it is convenient. And sure, those reasons are valid. But the real motivation runs deeper than keeping your car clean.
An unrestrained dog in a crash becomes a projectile. At 30mph, a 30kg Labrador hits whatever is in front of it with the force of roughly a tonne. That is your windscreen, your chest, or your child in the back seat. The Highway Code has been clear about this since 2022. Rule 57 states that dogs should be suitably restrained so they cannot distract you while you are driving or injure you, or themselves, if you stop quickly. It is a legal requirement, not a suggestion.
Then there is the comfort side. Dogs get hot in cars far faster than humans do. They get car sick. They get anxious. The right accessories address all of these problems. A window shade stops the sun beating down on them. A proper harness means they are not thrown around every time you brake. A travel water bottle keeps them hydrated on long drives. These are practical solutions to real problems, not gimmicks.
There is also the insurance angle. If you have an accident and your dog was loose in the car, your insurer could argue you were driving without proper control. That is a messy situation you want to avoid. A few well-chosen accessories sort this out completely.
UK law on dogs in cars
Let me get the legal stuff out of the way first because it matters. The Highway Code Rule 57 says you must restrain your dog in a way that prevents them from distracting you or injuring themselves or others. The wording is broad enough to cover a few different approaches. A seatbelt harness, a travel crate, a dog guard behind the back seats, or a secured carrier all count. A dog sitting loose on the back seat does not.
If you are pulled over and your dog is unrestrained, you can get a fine and points on your licence. The standard fixed penalty for driving without due care and attention is £100 and 3 penalty points, but if the case goes to court the fine can be much higher. The police do enforce this, particularly around checkpoints and during holiday weekends when more people are travelling with pets.
It is also worth knowing about the rules around leaving dogs in cars. Under the Animal Welfare Act 2006, leaving a dog in a car in conditions that could cause suffering is an offence. That includes hot weather, but it also applies in freezing conditions. Even on a mild day, the temperature inside a car can rise to dangerous levels within minutes. The RSPCA deals with thousands of calls about dogs left in cars every summer. Do not risk it.

Car harnesses
A car harness is probably the single most important piece of dog car travel kit you will buy. It is the thing that keeps your dog safe in a crash and stops them from launching themselves at the window every time a cyclist goes past.
Car harnesses are different from walking harnesses. A car harness has reinforced straps, heavy-duty buckles, and a loop or strap that clips directly into your car’s seatbelt system. You put the harness on your dog, buckle them into the back seat, and adjust the strap so they can sit or lie down but cannot move around the car. Simple.
The best car harnesses are crash-tested. That means the manufacturer has actually put the harness through a simulated crash scenario to prove it holds up. The Sleepypod ClickIt Sport and the Ruffwear Load Up are two of the most well-known crash-tested options, though both are American brands and can be harder to find in the UK. If you want something easier to get hold of, Amazon UK has a decent selection of crash-tested harnesses from brands like Ancol and EzyDog.
Fit matters more than you might think. A loose harness is almost useless in a crash because the dog can slip out of it. A harness that is too tight will be uncomfortable and your dog will hate wearing it. You want a snug fit where you can slide two fingers between the harness and your dog’s body. Most harnesses come with sizing charts based on your dog’s weight and chest measurement. Take the time to measure your dog properly before buying. Guessing their size based on how big they look almost never works out well.
Get your dog used to wearing the harness before you actually need to travel. Put it on them in the house for short periods, give them treats, and let them associate it with positive things. If the first time they wear it is a two-hour drive to the coast, they will probably hate it and make the journey miserable for both of you. We have written more about choosing the right car harness on our car harness guide if you want the detailed breakdown.
Car seat covers
Even if you do not care about your car’s upholstery (and fair enough if you drive an old van), a seat cover makes life easier. It catches mud, hair, drool, and whatever your dog has been rolling in at the park. When the journey is over, you pull it off and shake it out. Your actual seats stay clean.
There are two main types. Hammock-style covers drape over the back seat and attach to the front headrests as well as the rear ones. This creates a sort of sling that stops your dog from falling into the footwell and also protects the back of your front seats from muddy paws. Bench-style covers just sit on the back seat itself and are simpler but less comprehensive.
I would go with the hammock style every time. The footwell protection alone is worth it, and it stops your dog from trying to climb between the seats while you are driving. Look for covers that are waterproof or at least water-resistant. A dog that has been swimming will soak through a thin fabric cover in seconds and still ruin your seats. Quilted covers with a waterproof backing are the way to go.
Installation varies between models. Most use straps that loop around the headrests and clips or elastic that hooks under the seat. Some have openings for seatbelts so you can still use a car harness. Check for that if you plan to use both products together, because not every cover works well with a seatbelt harness.
You can pick up a decent car seat cover for £15 to £40 on Amazon UK. More expensive models tend to have thicker padding, better waterproofing, and more secure attachment points. Cheaper ones do the job for occasional use but might shift around more on longer journeys.
Car ramps
Car ramps are one of those things you do not think you need until your dog starts struggling to jump into the boot. That moment usually arrives gradually. First they hesitate a bit before jumping in. Then they need a little boost. Then they refuse to jump at all and you are left lifting a 35kg dog into the back of your car every time you go anywhere.
For older dogs, dogs with joint problems, and smaller breeds that cannot reach the boot of a 4×4 or estate, a car ramp solves this completely. The dog walks up the ramp at a gentle angle and into the car under their own steam. No jumping, no lifting, no risk of them injuring themselves on the way in or out.
Telescopic ramps are the most practical option because they fold down to a manageable size for storage. A good ramp extends to about 1.5 to 1.8 metres, which gives a comfortable angle for most cars. If you have a particularly tall vehicle, you might need a longer one. Measure the height of your boot opening before buying. A ramp that is too short will be too steep and your dog will not want to use it.
Surface grip is important. Ramps with a non-slip surface, rubber ridges, or carpet-style covering give your dog’s paws something to grip. Smooth plastic ramps are sketchy in wet weather and your dog will sense that immediately. If they feel insecure on the ramp, they will not use it, and you have wasted your money.
Training your dog to use the ramp takes a bit of patience. Set it up on flat ground first and lure them across with treats. Once they are comfortable walking on it, gradually raise one end. Take it slowly. Some dogs take to it in minutes. Others need a few sessions over a few days. Do not rush the process or try to force them up the ramp, because that will make them more resistant next time.
Expect to pay £30 to £80 for a decent car ramp. Budget models exist for less, but the build quality and grip surface tend to reflect the price.
Travel water bottles and bowls
Dogs need access to water during car journeys, especially in warm weather. They cannot tell you they are thirsty, and by the time they show obvious signs of dehydration like excessive panting or dry gums, they are already quite dehydrated. Keeping water available is basic care.
Travel water bottles are designed to be spill-proof, which matters a lot in a moving car. A regular water bowl sloshes water everywhere on corners and roundabouts. Travel bottles have a nozzle or dispenser that releases water when your dog licks or you squeeze the bottle. Some double as bowls with a flip-out tray that the dog drinks from. Others are simpler squeeze bottles with a roller ball on top.
H variable designs work. The important thing is that your dog will actually drink from it. Some dogs are fussy about drinking from unfamiliar dispensers. If that is your dog, a collapsible travel bowl is probably the better option. These fold flat for storage and pop open when you need them. You fill them from a regular water bottle at rest stops. They do spill, so you would only use them when the car is parked, not while driving.
Stainless steel travel bowls are the most durable option. They do not absorb smells, they are easy to clean, and they last forever. Silicone collapsible bowls are lighter and more portable but can retain odours over time, particularly if you use them for food as well as water. Plastic bowls are cheap and light but scratch easily and can harbour bacteria in the scratches.
For longer trips, pack more water than you think you need. A dog needs roughly 50 to 60ml of water per kilogram of body weight per day, and they will need more than usual in a hot car. Keep a spare bottle in the boot. You do not want to be searching for a shop that sells bottled water when your dog is panting on the hard shoulder.
We have a full guide to travel bowls for dogs on the site if you want to compare specific products and read our testing notes.
Car barriers
A car barrier, sometimes called a dog guard, is a metal or mesh grille that fits between the back seats and the boot area. It keeps your dog in the boot and stops them from coming through to the passenger area while you are driving.
Barriers are particularly useful if you have an estate car, SUV, or hatchback with a decent-sized boot. They are less practical in saloons or smaller cars where the boot is separate from the cabin. If you regularly take your dog to the beach or the woods and they come back covered in mud, sand, or worse, a barrier keeps all that mess confined to the boot area. Your seats stay clean and your passengers do not get a face full of wet dog hair.
There are three main types. Universal mesh barriers are the cheapest and most adjustable. They use tension rods and straps to fit across the gap between the seats, and they work in most cars but can be a bit fiddly to set up. They also tend to rattle on rough roads, which gets annoying on long drives.
Metal grid barriers are more solid and more expensive. Many car manufacturers sell them as official accessories designed specifically for their models. These are the best option if one exists for your car because they fit properly and do not move around. They also look more like a factory fit and less like something you have bolted in as an afterthought.
Canvas barriers are a middle ground. They use heavy-duty fabric stretched across a frame. They are lighter than metal barriers and easier to install, but they are not as sturdy. A determined large breed could probably push through one, so they are better suited to smaller or calmer dogs.
One thing to consider with barriers is visibility. Some mesh barriers can partially block your rearview mirror view. Test the fit before you buy if possible, or check reviews from owners of the same car model. If you cannot see properly out the back, the barrier is creating its own safety problem.
Boot liners
Boot liners and car barriers go hand in hand. If your dog travels in the boot, you need something to protect the boot floor and sides from claws, muddy paws, and whatever they decide to roll in. Car boot carpets are expensive to replace, and dog damage is not covered by most warranties.
Custom-fit boot liners are made to the exact shape of your car’s boot. They cover the floor, the sides, and sometimes the back of the rear seats. Brands like Boot Buddy and Travall make these for specific car models, and the fit is excellent. Everything lines up perfectly, the liner does not slide around, and it looks like it belongs there. The downside is the price. A custom-fit liner typically costs £50 to £120 depending on your car.
Universal boot liners are cheaper and less precise. They are essentially large rubber or heavy fabric mats that you trim or fold to fit your boot. They protect the floor but usually not the sides. For basic protection against mud and hair, they work fine. If you want full coverage, you are better off spending more on a custom option.
Material matters. Rubber liners are waterproof and easy to hose down, which is brilliant after a beach trip. But they can be slippery, and some dogs do not feel secure standing on them. Fabric liners with a waterproof backing give your dog more grip but are harder to clean. A rubber liner with a textured surface or a non-slip mat on top is a good compromise.
Think about how you use your boot the rest of the time. If you regularly fold the rear seats down for cargo, make sure the liner is easy to remove or compatible with folded seats. Some custom liners have flaps that fold with the seats. Others need to be taken out completely.
Window shades
Window shades are simple, cheap, and genuinely useful. They block direct sunlight from coming through the side windows, which keeps the car cooler and stops the sun from being in your dog’s eyes. If you have ever driven west in the late afternoon with the sun streaming through the passenger side, you will know how uncomfortable that is for a dog who cannot squint, put on sunglasses, or pull a hat down over their face.
Static cling shades are the easiest to use. They stick to the window using static electricity, no adhesive needed. You press them on, smooth out the bubbles, and they stay in place. To remove them, you just peel them off. They are reusable and you can move them between windows or cars. They cost about £5 to £15 for a pair.
Suction cup shades are another option. They attach with small suction cups and tend to stay in place more securely than static cling versions on bumpy roads. The downside is that suction cups can fail, particularly in very hot weather when the rubber softens. They also leave little circular marks on the window, which matters to some people more than others.
Mesh shades are a third type. These are fine nets that you stretch across the inside of the window frame. They let air through while blocking some sunlight, which is useful in summer. They also double as a basic insect screen if your dog likes to have the window cracked open. Mesh shades tend to be less effective at blocking heat than solid shades, but the airflow benefit makes up for it on warm days.
Whichever type you choose, make sure the shades do not block your visibility as the driver. Avoid putting them on the front side windows if they are too dark. Rear side windows are the best position for dog comfort. And never put a shade on the windscreen or rear window, because that is dangerous and probably illegal depending on the size and position.
How to prepare for a long trip with your dog
Longer journeys need more planning than a quick drive to the park. A few hours on the motorway with an unhappy, uncomfortable dog is a grim experience for everyone involved. A bit of preparation before you set off makes the whole thing smoother.
Feed your dog at least two hours before you leave. A full stomach sloshing around in a moving car is one of the main triggers for car sickness. If your dog is prone to being sick in the car, you might want to feed them even earlier or skip the meal entirely and feed them when you arrive. A hungry dog is uncomfortable but a vomiting dog is a whole other problem. If you need advice on feeding schedules around travel, our dry dog food guide covers routine feeding for active dogs.
Exercise your dog before the journey. A tired dog is a calm dog. A 30-minute walk or a good run before you set off burns off excess energy and makes them more likely to settle during the drive. Do not overdo it, especially in warm weather, because an exhausted, overheated dog will be just as unhappy in the car as an under-exercised one.
Plan your route with rest stops in mind. For a journey of two hours or more, aim to stop every 1.5 to 2 hours. Your dog needs a chance to stretch their legs, have a drink, and go to the toilet. Service stations on motorways usually have designated dog walking areas. On A-roads, look for lay-bys or pubs with gardens where you can pull over safely.
Bring a travel kit. Water, a bowl, poo bags, a towel (for wet dogs or cleaning up spills), a familiar blanket or bed for comfort, and any medication your dog needs. If you are staying overnight, pack their usual food rather than buying something unfamiliar at the other end. A sudden change of food on top of travel stress is a recipe for an upset stomach.
Keep the car well ventilated. Open a window a couple of inches on each side to create airflow through the car. Air conditioning helps but do not blast it directly onto your dog. Fresh air from open windows is more comfortable for most dogs. Use the window shades on the sunny side of the car and consider which side that will be at different times of day. Sun position changes as you drive, so you might need to move the shades during a break.
Bring something familiar. A dog’s own bed, a favourite toy, or a worn t-shirt that smells like you provides comfort and reduces anxiety. Dogs rely heavily on scent, and having familiar smells in an unfamiliar environment (like a car travelling at speed) helps them settle. This is particularly important for anxious dogs or puppies on their first long journey.
Car sickness in dogs
Car sickness is incredibly common in dogs, especially puppies and young dogs. Their inner ear, which controls balance, is still developing, and the motion of a car confuses it. Most dogs grow out of car sickness as they mature, but some never do. If your dog is one of them, there are things you can do to help.
The basics are worth repeating because they actually work. Do not feed your dog right before the journey. Keep the car cool and well ventilated. Avoid reading or looking at screens if you are a passenger, and try to keep the dog facing forward rather than sideways. Facing forward reduces the visual confusion that contributes to nausea.
If your dog only gets mildly queasy, ginger can help. A small amount of fresh ginger or a ginger biscuit (check it does not contain xylitol) about 30 minutes before travel can settle the stomach. Some pet shops sell ginger-based travel supplements specifically for dogs. The evidence is mostly anecdotal rather than clinical, but plenty of dog owners swear by it.
For more severe car sickness, talk to your vet. They can prescribe anti-nausea medication like maropitant (Cerenia), which is specifically licensed for dogs and is very effective. It is not something you want to use for every short trip, but for a long journey or a dog that really suffers, it makes a huge difference. Your vet might also suggest a sedative or anti-anxiety medication if the car sickness is driven by stress rather than motion alone.
Desensitisation works for some dogs. The idea is to gradually get them used to the car in small steps. Sit in the parked car together with treats. Then start the engine without moving. Then drive to the end of the road and back. Gradually increase the distance over several sessions. If your dog shows signs of nausea at any point, go back to the previous step. This takes patience, sometimes weeks, but it can permanently solve the problem for some dogs.
Some dogs only get car sick when they can see out the window. The fast-moving scenery makes them feel dizzy. If that sounds like your dog, try blocking their view with a window shade or covering their crate with a light blanket. If they settle down immediately, motion sickness triggered by visual input is likely the cause.
The PDSA has a good overview of car sickness in dogs and when to seek veterinary help. The Blue Cross also covers travel anxiety, which often goes hand in hand with car sickness.
Where to buy dog car travel accessories in the UK
You have got options, which is good for comparing prices but can be overwhelming when you just want to buy a seat cover and get on with your day.
Amazon UK has the biggest selection by far. Car harnesses, seat covers, ramps, travel bowls, barriers, boot liners, window shades. They have it all, often with next-day delivery if you have Prime. The customer reviews are useful for weeding out the duds, though you need to read them with a critical eye because some of the five-star reviews for cheap products are clearly fake. Look for reviews that include photos and mention how the product has held up over time.
Pets at Home is the biggest pet retailer in the UK and stocks a decent range of car travel accessories in their larger stores and online. The advantage of buying in person is that you can check the quality and sizing before you part with your money. Their own-brand range is reasonable value, and they often have exclusive products you will not find on Amazon.
Julius K9 is a Hungarian brand with a strong UK presence. Their car harnesses and harnesses are well regarded and widely available from their UK website and various stockists. The quality is good, the sizing is reliable, and their products have a reputation for lasting. If you want a harness that will still be going strong in five years, Julius K9 is a solid bet.
For boot liners, brands like Boot Buddy and Travall specialise in custom-fit liners for specific car models. Check their websites to see if they make one for your car. The fit is worth paying extra for if you use your boot regularly for your dog.
Smaller independent pet shops often stock a curated selection of travel accessories. The advantage here is that the staff usually have dogs themselves and can give you honest advice about what works. If you have a local shop, it is worth a visit before ordering online. You might find something you would not have thought to look for.
Second-hand options exist on eBay and Facebook Marketplace, particularly for car barriers and boot liners. I would be cautious with harnesses, though. A second-hand harness might have invisible damage from a previous crash or years of use. For anything that is responsible for your dog’s safety in a collision, buy new from a reputable seller.
Frequently asked questions
Can my dog sit on my lap in the car?
No. Apart from being dangerous and illegal, it is a terrible idea. A dog on your lap restricts your ability to steer and use the pedals. In a crash, an unrestrained dog on your lap will be crushed between you and the airbag. Your dog might enjoy sitting on your lap in the living room, but the car is not the place for it. Use a harness or a crate instead.
What is the best way to restrain a dog in a car?
It depends on your car and your dog. A crash-tested car harness on the back seat is generally considered the safest option for most dogs. A secured crate or carrier is also very safe and works well for smaller dogs. A dog guard or barrier is better than nothing for the boot, but it does not protect your dog from being thrown around in a crash the way a harness or crate does.
Do car harnesses actually work in a crash?
Crash-tested harnesses have been proven to hold up in simulated crash conditions at speeds up to around 30mph. Non-crash-tested harnesses vary enormously in quality. Some would probably hold. Others would tear or the buckles would fail. If safety is your priority, buy a harness that explicitly states it has been crash-tested and check for independent certification rather than just taking the manufacturer’s word for it.
How do I stop my dog from barking in the car?
Barking in the car is usually down to excitement or anxiety. If your dog barks at everything they see out the window, try a window shade to block their view. If they bark because they are anxious, desensitisation training and creating a comfortable, familiar space in the car (their own bed, familiar smells, a covered crate) can help. Do not punish barking in the car, because that usually increases anxiety and makes the problem worse. Some dogs bark less if they are tired, so a good walk before the journey can make a big difference.
Are dog car seat covers machine washable?
Most are. Check the label before you buy, but the majority of fabric and quilted seat covers can go in the washing machine. Rubber and waterproof-backed covers usually just need a wipe down or a hose off. A few covers have removable inserts that wash separately. If your dog gets particularly muddy, a washable cover saves you a lot of hassle.
Can I use a regular walking harness in the car?
I would not recommend it. Walking harnesses are designed for control during walks, not for crash protection. The straps are lighter, the buckles are not reinforced, and there is usually no way to attach them to the seatbelt system. In a crash, a walking harness is likely to tear or slip off. Car harnesses are specifically engineered and tested for the forces involved in a collision. Spend the extra money and get the right tool for the job.
How do I know what size car harness to buy?
Measure your dog’s chest circumference, which is the widest part just behind their front legs, and their neck. Check the manufacturer’s sizing chart and match your measurements to their sizes. Do not guess based on your dog’s weight alone, because dogs of the same weight can have very different body shapes. A whippet and a Staffordshire bull terrier might weigh the same but need completely different harness sizes. If your dog is between sizes, go up rather than down.
Are car barriers legal in the UK?
Yes, car barriers and dog guards are legal and satisfy the Highway Code requirement to restrain your dog in a vehicle. They keep the dog in the boot area and prevent them from entering the passenger space. They are widely used and accepted. Just make sure the barrier is securely fitted and cannot be pushed aside by your dog.
What should I do if my dog gets car sick?
Start with the basics. Do not feed them within two hours of travel. Keep the car cool and well ventilated. Face them forward and consider blocking side windows with shades. For mild cases, ginger supplements can help. For persistent or severe car sickness, speak to your vet about anti-nausea medication. Puppies often grow out of car sickness as their inner ear matures, usually by around one year of age.
How often should I stop on a long journey with my dog?
Every 1.5 to 2 hours as a general rule. Your dog needs water, a chance to go to the toilet, and a few minutes to stretch their legs and move around. If it is hot, you may need to stop more often. Do not leave your dog in the parked car at rest stops, even for a few minutes. Take them with you or stay with the car with the doors open and windows down.
Do I need a car ramp for a small dog?
It depends on your car. If you drive an SUV, 4×4, or a high-boot estate, even a small dog might struggle to jump in. A ramp is also useful if your small dog has short legs or a long back, like a Dachshund, because repeated jumping puts strain on their spine. For a standard hatchback or saloon, most small dogs can manage the jump without a ramp. Watch your dog and let them tell you if they need help.
A final thought on travelling with your dog
Getting the right dog car travel accessories does not need to be complicated or expensive. A crash-tested harness, a decent seat cover or boot liner, and a way to give your dog water cover the basics. Add a car ramp if your dog struggles to jump in, a barrier if they travel in the boot, and window shades for hot days. That is pretty much the complete setup.
The legal side is straightforward. Restrain your dog properly and you are complying with the Highway Code. Fail to do so and you are risking a fine, points on your licence, and serious injury to your dog and anyone else in the car. The accessories that keep you legal are the same ones that keep your dog safe. There is no conflict there.
Travel with your dog should be enjoyable. A well-equipped car means fewer stops for cleaning up mess, less stress for your dog, and a more relaxed journey for you. The Lake District, the Scottish Highlands, the Pembrokeshire coast. Some of the best trips you can take in the UK are better with a dog in the back. Sort out the car setup once and you are ready for all of them.
