Why dogs get car sick
Motion sickness occurs when the vestibular system in the inner ear detects movement that the eyes and the rest of the body do not confirm. In puppies it is especially common because the inner ear is not fully developed β many improve on their own by around one year of age.
In adult dogs, anticipatory anxiety plays an equally important role: if car journeys have been associated with vet visits or other unpleasant experiences, emotional stress can worsen or even trigger symptoms on its own.
Symptoms of car sickness
- Excessive drooling.
- Lip licking or repeated yawning.
- Restlessness, inability to settle.
- Vomiting.
- Panting and trembling.
- Refusing to get into the car.
Solutions without medication
Gradual desensitisation to the car
- Dog next to the parked car β treats. Repeat until calm.
- Dog inside parked car, engine off β treats.
- Engine on, not moving β treats.
- Very short trips (100 m) towards something positive (the park).
- Gradually increase distance.
Practical adjustments
- No food for 3β4 hours before the journey.
- Ventilate the car well β heat worsens motion sickness.
- Forward-facing position (facing rearwards in the boot is worse).
- Frequent stops on longer journeys.
Medication when desensitisation is not enough
- Maropitant (Cerenia): dog-specific antiemetic, highly effective against vomiting. Prescription required. Give 2 hours before travel.
- Diphenhydramine (antihistamine): mild sedation + antiemetic effect. Check dose with your vet.
- Gabapentin or trazodone: if anxiety is the dominant component, prescribed by the vet as pre-medication.
For journeys over 8 hours (flights, trains), always consult your vet about the best protocol.
