Travelling by Car With a Dog or Cat

By Sam Whitlow · Published Sep 21, 2026 · 6 min read

Some dogs leap into the car with enthusiasm. Others drool, pant, or vomit before you reach the end of the street. Most cats would rather not travel at all.

With preparation, journeys can be safer and less stressful for everyone.

Restrain your pet safely

An unrestrained pet can distract the driver and become a dangerous projectile in a sudden stop. In some countries, driving with an unrestrained pet can lead to fines or affect insurance. Use a crash-tested crate, carrier, or harness attached to a seat belt. Cats should always travel in a secure carrier.

Get them used to the car

  • Start with sitting in the stationary car with treats
  • Progress to short trips that end somewhere fun
  • Leave a cat’s carrier out at home so it becomes a familiar resting place
  • Use familiar bedding that smells of home

Preventing car sickness

Feed a light meal a few hours before travelling rather than just before. Keep the car cool and well ventilated. Many puppies grow out of car sickness. If it persists, your vet can prescribe anti-nausea medication.

On longer journeys

  • Stop every couple of hours for a toilet break, water, and a short walk
  • Keep dogs on a lead at service stations
  • Bring water, a bowl, waste bags, food, and any medication
  • Make sure your pet’s microchip details and ID tag are up to date

Never leave pets in a hot car

Cars heat up quickly, even on mild days and with windows slightly open. Dogs and cats can develop heatstroke in minutes. If you cannot take your pet with you when you leave the car, do not bring them.

Travelling abroad

Travelling across borders usually requires a microchip, up-to-date rabies vaccination, and official health documents, sometimes with waiting periods and tapeworm treatment. Rules vary by country and change over time, so check official government guidance well in advance.
