Car sickness is far more common in puppies than adults, and far more often behavioural than owners assume. The inner ear structures involved in balance are not fully developed in young dogs, so many puppies genuinely do feel unwell — and then, having felt unwell in a car several times, learn to dread the car itself.
That is why plenty of dogs grow out of the physical part and keep the drooling, panting and vomiting. The stomach has stopped being the problem and the anticipation has taken over.
Working out which you have
Physical motion sickness tends to involve: drooling from the start of the journey, licking lips, yawning, vomiting after ten to twenty minutes, and being fine the instant the car stops.
Anxiety tends to involve: reluctance to approach the car at all, trembling, whining, panting that starts before the engine does, and vomiting sooner than motion alone would explain.
Most dogs with a long history have both, which is why the plan below addresses both together.
Step one: break the association
Stop taking the dog anywhere for a fortnight. Every sick journey reinforces the problem, so the training starts with no journeys at all.
Instead, work through these stages, moving on only when the dog is relaxed at the current one:
- Feed meals near the parked car
- Feed meals in the open boot or on the back seat, engine off, doors open
- Sit in the car with the dog, doors closed, for two minutes. Read something. Leave.
- Engine on, stationary, one minute. Off. Out.
- Reverse onto the drive and back. Out.
- Drive to the end of the road and back.
- Two minutes’ drive, to somewhere brilliant — a field, not the vet.
This takes two to four weeks for most dogs. Rushing it restarts the clock.
Step two: fix the position
Where the dog travels makes a substantial difference to motion sickness.
- Facing forwards reduces the mismatch between what the eyes see and what the inner ear feels.
- Able to see out of the windscreen, if possible, for the same reason. Dogs travelling in a covered crate with no view are often worse.
- Low and stable, in a footwell or a secured crate, rather than sliding around on a seat.
- Middle of the car rather than the very back, where the pitching motion is greatest.
Restraint is a legal requirement in many places and a safety necessity everywhere: an unrestrained dog in a collision is a projectile.

A crash-tested harness with a seatbelt tether, which keeps the dog upright and facing forward rather than sliding on corners. Adjust it so the dog can sit and lie down but not turn around.

Hard Bottom Dog Car Seat Cover
A rigid base stops the dog sinking into the footwell gap and gives a stable, level surface, which helps more with sickness than a soft hammock does.
Step three: practical changes that help
- Do not feed within two to three hours of travelling. An empty-ish stomach is better, though a completely empty one can make nausea worse in some dogs — a small biscuit an hour before is a reasonable compromise.
- Cool air. Drop the windows a couple of inches for airflow and keep the car cool. Stuffy warm cars make everything worse.
- Reduce visual motion. Blocking the side windows so the dog sees forward rather than the scenery whipping past reduces sickness in many dogs.
- Drive gently. Fewer sharp corners, less hard braking. Dogs cannot brace for what they cannot anticipate.
- Break up long journeys every hour for a short walk and a drink.
- Familiar bedding from home rather than something new.

Step four: talk to your vet
If the plan above is not enough, there is effective medication.
- Maropitant is a prescription anti-nausea drug licensed for motion sickness in dogs and is highly effective. It is given a couple of hours before travel.
- Anti-anxiety medication may be appropriate for dogs whose problem is primarily fear, either for occasional journeys or alongside a behaviour plan.
What not to do
- Do not punish or scold a dog for being sick. It is not a choice.
- Do not fuss dramatically either; calm, matter-of-fact clean-up is best.
- Do not push through a long journey hoping the dog will “get used to it”. Flooding usually entrenches the fear.
- Do not let a dog ride with its head out of the window. Eye injuries, ear damage and worse.
Realistic expectations
Puppies who are physically car sick usually improve considerably by around a year old as the inner ear matures. Dogs whose problem is learned take a few weeks of staged work to turn round. A small number need medication for life, and that is an entirely reasonable outcome — some people take travel sickness tablets too.
The goal is not a dog who loves the car. It is a dog who gets in without dread and arrives able to enjoy wherever you have taken it.
