Few things put a dampener on a day out quite like a dog who drools, whines and is sick before you've reached the end of the road. Car sickness is really common in dogs, and it's especially common in puppies, but that doesn't make it any less miserable for them or for you.
The good news is that most dogs either grow out of it or can be helped to travel much more comfortably. In this guide we explain why dogs get car sick, the early signs to look out for, how to tell sickness from travel nerves, and the practical steps that make journeys easier.
If your dog is sick on every journey, or car sickness starts suddenly in an older dog, it's always worth speaking to your vet. They can rule out other causes and, if needed, prescribe anti-sickness medication made for dogs.
Why do dogs get car sick?
Car sickness is a form of motion sickness. Your dog's sense of balance comes from the vestibular system in the inner ear, which senses movement. In a car, the inner ear feels the motion while the eyes, looking at the inside of the car, tell the brain everything is still. That mismatch is what triggers nausea.
Puppies are the most likely to suffer. The structures in a young dog's inner ear are still developing, so their balance is easily thrown. Many puppies who are sick on every trip are travelling happily by the time they're around a year old.
Anxiety plays a big part too. If a puppy's early car journeys meant feeling sick, or only ever ended at the vet, they can learn to associate the car with feeling awful. That stress can bring on drooling and vomiting even after their inner ear has matured, which is why some adult dogs stay car sick for life.
Other things can make it worse: a full stomach, a hot or stuffy car, winding country roads, stop-start traffic, and travelling in the back of a hatchback or estate, where the motion is greatest.
Signs your dog is feeling car sick
Vomiting is the obvious sign, but most dogs show earlier clues first. Spotting these lets you pull over, open a window or take a break before things get worse.
Car sickness signs to look out for
| Early signs | Later signs |
|---|---|
| Yawning and lip licking | Heavy drooling |
| Whining or restlessness | Retching or vomiting |
| Unusually still or listless | Diarrhoea or needing the toilet |
| Ears back, looking worried | Reluctance to get back in the car |
For guidance only, not a diagnosis.
Some dogs go very quiet rather than restless, which is easy to mistake for a dog who's settled. If your normally chatty dog is suddenly motionless and swallowing a lot, nausea is often the reason.
Car sickness or travel anxiety?
The two often overlap, and one can lead to the other, but it helps to know which you're mainly dealing with because the approach is a little different.
Car sickness vs travel anxiety
| Mainly car sickness | Mainly travel anxiety | |
|---|---|---|
| When it starts | After the car has been moving for a while | Before the car moves, sometimes at the sight of the keys |
| Typical signs | Drooling, lip licking, vomiting | Panting, pacing, whining, trying to escape |
| Short trips | Often fine | Still stressful |
| What helps most | Less motion, fresh air, an empty stomach | Slow, positive practice and building confidence |
For guidance only. Many dogs show a mix of both.
If your dog shows signs of stress in other situations too, such as being left alone, our guide to separation anxiety covers how to build their confidence more generally.
How to help a car sick dog
Small changes to how and where your dog travels can make a real difference. It's worth trying several of these together.
Travel on an empty stomach. Avoid feeding your dog for 2 to 3 hours before a journey. Make sure they still have access to water, and offer a small drink at stops.
Reduce the motion they feel. Dogs tend to cope better nearer the middle of the car than right at the back. A secure, crash-tested harness on the back seat or a well-fitted crate stops them sliding around, and a dog who can see out of the front windscreen often feels less sick than one staring at the seat in front.
Keep the car cool and fresh. Open a window a little to let fresh air in and keep the temperature comfortable. Stuffy, warm cars make nausea worse, and strong air fresheners don't help either.
Drive smoothly and take breaks. Gentle acceleration and braking, and avoiding winding roads where you can, all help. On longer journeys, stop regularly so your dog can stretch their legs, have a sniff and settle their stomach.
Keep them safely restrained. The Highway Code says dogs should be suitably restrained in a car so they can't distract you or be hurt if you stop quickly. A seat belt harness, pet carrier, dog cage or dog guard all work, and a secure dog is usually a calmer dog too.
Ask your vet about medication. For dogs who are sick despite all of this, vets can prescribe anti-sickness medication made for dogs. Never give your dog human travel sickness tablets, as some ingredients can be harmful to dogs.
Getting your dog used to the car
For puppies and anxious dogs, the aim is to teach them that the car is a good place to be. Go slowly, and only move on to the next step when your dog is relaxed with the current one.
Start with the car parked and the engine off. Sit with your dog in the car for a few minutes, give treats and praise, then get out. Once that's easy, try the same with the engine running. Next, take very short trips of just a few minutes, ideally ending somewhere your dog loves, like the park or a favourite walk, rather than the vet.
Build up the length of journeys gradually. Keep the mood calm and upbeat, bring a familiar blanket that smells of home, and don't punish your dog for being sick or anxious, as that only adds to the stress.
Older dogs and car travel
If an older dog who has always travelled well suddenly becomes wobbly, unsteady or sick in the car, don't assume it's simple car sickness. Problems with balance in older dogs, such as vestibular disease, can look similar, so it's important your vet takes a look.
It's also worth watching how your older dog gets into the car. A dog who hesitates at the boot, needs lifting or seems sore after a journey may be struggling with stiff joints rather than nerves. Jumping in and out of a car puts a lot of strain on the hips, elbows and back, and a long journey spent in one position can leave them stiff when they get out.
A dog ramp for the car takes the strain out of jumping, and a supportive bed in the boot helps on longer trips. For day-to-day joint support, MedPaw's daily hip and joint supplement combines glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia in one soft chew to help support your dog's mobility and comfort.

When to speak to your vet
Most car sickness is unpleasant rather than dangerous, but there are times when a vet visit is the right call.
When car sickness needs a vet
Sick on most journeys
If simple changes haven't helped, ask your vet about anti-sickness medication and a training plan
Sickness carries on after the journey
Vomiting or diarrhoea that continues once you're home is unlikely to be car sickness and should be checked
Sudden wobbliness, head tilt or blood in vomit
Loss of balance, a head tilt, flicking eyes or blood in vomit need prompt veterinary attention
If you do spot blood, our guide to why a dog might vomit blood explains what to tell your vet. With a bit of patience, most car sick dogs can learn to enjoy travelling, and that opens up a lot more walks, holidays and adventures together.
Is car sickness the same as travel anxiety in dogs?
No, they're different conditions though they can look similar. Car sickness is a physical response to motion that affects your dog's inner ear balance, causing nausea and vomiting. Travel anxiety is an emotional response where your dog feels stressed or fearful about car journeys, which might cause panting, drooling or restlessness but not necessarily vomiting.
At what age do dogs typically outgrow car sickness?
Most puppies who experience car sickness will outgrow it by around 12 to 18 months of age as their inner ear develops fully. However, some adult dogs can still suffer from motion sickness throughout their lives. If your dog continues to be car sick beyond puppyhood, it's worth speaking to your vet about management strategies.
Can I give my dog human travel sickness tablets?
Never give your dog human medications without consulting your vet first, as many can be toxic to dogs. Your vet can prescribe safe anti-nausea medications specifically designed for dogs if needed. There are also natural approaches like ginger treats or gradual desensitisation training that might help, but always check with your vet before trying new remedies.
How can I tell if my dog's car problems are sickness or anxiety?
Car sickness typically involves vomiting, excessive drooling and lethargy, whilst travel anxiety shows as panting, whining, pacing or trying to escape the car. Some dogs show signs of distress before the car even moves if it's anxiety-related. If you're unsure which your dog is experiencing, your vet can help you identify the cause and suggest appropriate solutions.
Should I feed my dog before a car journey?
It's generally better to avoid feeding your dog for 2-3 hours before travelling to reduce the risk of car sickness. A small treat or light snack might be acceptable for very long journeys, but an empty stomach usually travels better. Always ensure your dog has access to fresh water during stops, and speak to your vet if you're planning particularly long trips.
