Travel sickness in dogs: how to recognise, prevent and treat car sickness

August 01 2026, by Michael van Wassem, 7 min reading time

Does your dog drool or whine as soon as the car starts moving? Discover why dogs get travel sick, how to recognise it, and the tips that help prevent it.

Your dog drools heavily, yawns anxiously, or even vomits as soon as the car starts moving. Travel sickness (also called car sickness) is more common in dogs than many owners realise, and it affects puppies and young dogs most often. The short answer: travel sickness happens because the signals from the inner ear, the eyes and the body contradict each other while the car is moving, and with the right gradual training, positioning and preparation, it can usually be reduced significantly or even resolved.

What exactly is travel sickness in dogs?

Just as in people, travel sickness results from a mismatch between what the balance organ in the inner ear senses and what the eyes see. In a moving car, your dog's body feels motion, while the eyes often only see the stationary inside of the car. That conflict confuses the brain and can cause nausea, dizziness and vomiting.

In puppies and young dogs, there is an extra factor: the balance organ isn't fully developed yet, which makes them especially sensitive to this signal confusion. Many puppies grow out of it naturally as the balance organ matures, usually somewhere between eight and twelve months of age.

💡 In older dogs who only start showing symptoms during car rides later in life, the cause is more often stress or a bad past experience rather than true motion sickness. It's important to tell the two apart, because the approach differs.

Recognising the symptoms of travel sickness

The signs often start before the car has even moved, simply because your dog recognises the lead-up to a ride. Watch for:

• Excessive drooling, often starting as soon as your dog gets in.
• Repeated yawning and lip-licking, a classic sign of nausea in dogs.
• Restless panting without it being warm.
• Whining or crying during the journey.
• Listlessness, or restless pacing on the back seat.
• Vomiting, often within the first ten to thirty minutes of the drive.

Travel sickness or car anxiety: telling the difference

These two are often confused, even though the solution is different. With true travel sickness, symptoms are caused by the motion itself, even if your dog starts the journey relaxed. With anxiety, you often see stress before the car even sets off: trembling, refusing to get in, anxious panting, or trying to escape.

In practice, the two often overlap: a dog who has felt seriously unwell a few times starts associating the car with an unpleasant experience and becomes anxious about the next ride. That means travel sickness can eventually cause car anxiety too, even once the physical problem has been resolved.

Practical tips to prevent travel sickness

Most dogs benefit from a combination of the following measures:

• Don't feed a large meal right before you leave. An empty or lightly filled stomach considerably reduces the risk of vomiting. Always let your dog drink water, though.
• Let in fresh air. Open a window slightly so the air pressure inside the car matches the outside better; this reduces the sensory confusion.
• Let your dog look forward. A dog who can see forward rather than sideways can better anticipate the car's movements. A secure, well-fitted harness helps keep your dog calm and safely positioned facing the direction of travel.
• Build up short trips gradually. Start with rides of just a few minutes to somewhere fun (a park, not only the vet) and slowly extend the duration once your dog stays relaxed.
• Keep the car cool. A hot, stuffy car makes nausea worse. Make sure there's good ventilation or air conditioning, especially in summer.
• Take regular breaks on longer journeys so your dog can get out, drink and recover.
• Limit visual stimulation. A dog guard or a covered crate can reduce restlessness by limiting the amount of passing scenery your dog sees.

⚠️ Drive gently on the first practice trips and avoid winding roads or sudden braking: the more predictable the motion, the lower the chance of nausea.

Common mistakes when dealing with travel sickness

• Only practising with long journeys. Driving for an hour straight after a bad experience increases the risk of a new negative association.
• Comforting your dog in a high, excited voice as soon as they become restless. This confirms to your dog that something is indeed wrong, rather than calming them down.
• Travelling on a full stomach "just to be safe", while this actually increases the risk of vomiting.
• Concluding too quickly that a dog "just doesn't like the car" without investigating whether the cause is physical or anxiety-related.
• Giving human travel sickness remedies without guidance. Products made for people aren't automatically safe or effective for dogs.

When to see a vet

If your dog remains consistently unwell or anxious during car journeys despite the measures above, contact your vet. For dogs who need to travel often, for example for holidays or regular appointments, a vet can prescribe travel sickness medication that's specifically approved for dogs. Persistent vomiting, weight loss or extreme anxiety around car rides are also good reasons to discuss this with your vet, so other causes can be ruled out.

🐶 For dogs where stress plays a big role, a calming aid can help as a support alongside training. Think of a well-fitted, comfortable harness or collar, always used to support gradual habituation, never as a replacement for it.

Checklist: keeping your dog travel-sickness-free on the road

• ☐ No heavy meal right before departure
• ☐ Fresh air through a slightly open window
• ☐ Dog is secure and can look forward
• ☐ Short, positive practice trips built up before a long journey
• ☐ Car well ventilated and not too warm
• ☐ Regular breaks planned for long journeys
• ☐ Distinction made between travel sickness and anxiety
• ☐ Vet consulted if symptoms persist

Frequently asked questions

Do puppies grow out of travel sickness?

Many puppies improve naturally as the balance organ develops further, usually somewhere between eight and twelve months of age. Regular short, positive practice during this period helps stop the car from feeling threatening.

Does ginger help with travel sickness in dogs?

Some owners use ginger as a natural remedy, but its effect and the correct dosage for dogs aren't clearly established. Always talk to your vet before adding anything to your dog's diet, even something "natural".

Can I give my dog human travel sickness medication?

Never give human travel sickness remedies to your dog without consulting your vet first. Some ingredients are harmful to dogs or aren't correctly dosed for their body weight. There are veterinary medicines developed specifically for dogs that are only available through a vet.

How long does it take to get a dog used to the car?

This varies a lot from dog to dog. Some dogs are noticeably calmer within a few weeks of short, positive trips, while dogs with a longer history of bad experiences need more time and patience.

Summary

Travel sickness in dogs happens because the balance organ, the eyes and the body contradict each other while the car is moving, and it's most common in puppies and young dogs. Recognise the signs, such as drooling, yawning and vomiting, early, tell travel sickness apart from anxiety, and build up gradually with short, positive trips, fresh air and a safe, forward-facing position.

If your dog continues to struggle despite these adjustments, a conversation with your vet is the next step. At Fidello you'll find practical products to make every car journey with your dog more comfortable.
