Whether you are driving to the vet or heading off on a long road trip, traveling with a pet takes a little planning. An unrestrained pet can distract the driver and can be seriously injured in a sudden stop. Some pets also feel anxious or carsick in the car. This guide covers how to keep dogs and cats safe, calm, and comfortable on the road.

Why Restraint Matters
In a sudden stop or collision, an unrestrained pet can be thrown forward with great force, injuring itself and anyone in the car. A loose pet can also climb onto the driver’s lap, block the pedals, or escape through an open door. In many places, traffic laws require animals to be suitably restrained. Always secure your pet before you start the engine.
Safe Ways to Secure Your Pet
- Travel crate or carrier. A sturdy, well-ventilated crate is one of the safest options, especially for cats and small dogs. Secure it with a seat belt or place it in the footwell or cargo area so it cannot slide.
- Crash-tested car harness. For larger dogs, use a harness designed for car travel that attaches to the seat belt system. Never attach a seat belt to a collar, which can injure the neck.
- Cargo area barrier. For SUVs and estate cars, a sturdy dog guard keeps dogs in the back, but a crate or harness still offers better protection in a crash.
Cats should always travel in a secure carrier. Never let a cat roam free in a moving car.
Keep Pets Out of the Front Seat
The back seat or cargo area is the safest place for pets. Front airbags can seriously injure an animal, even in a minor accident. Pets in the front seat are also more likely to distract the driver.
Do Not Let Your Dog Hang Out of the Window
Many dogs love sticking their heads out of the window, but it is risky. Dust, insects, and small stones can injure eyes and ears, and dogs can fall or jump out. Open windows only slightly for fresh air, and use child locks on window buttons so your dog cannot open them with a paw.
Get Your Pet Used to the Car
If your pet only rides in the car to visit the vet, it may associate the car with stress. Help them build positive associations:
- Let your pet sit in the parked car with treats or a favorite toy.
- Start the engine without going anywhere, then reward calm behavior.
- Take short drives around the block, ending somewhere enjoyable such as a park.
- Gradually increase the length of trips.
For cats, leave the carrier out at home with a soft blanket inside, so it becomes a familiar resting place rather than something that only appears before a trip.
Preventing Car Sickness
Car sickness is common, especially in puppies, whose balance system is still developing. Signs include drooling, yawning, whining, restlessness, and vomiting. To help:
- Feed a light meal several hours before travel rather than right before you leave.
- Keep the car cool and well ventilated.
- Have your pet face forward if possible, and drive smoothly.
- Take breaks on longer journeys.
Many puppies outgrow car sickness. If it continues, talk to your veterinarian, who may recommend medication. Never give human travel sickness medicine to a pet without veterinary advice.
What to Pack for a Road Trip
- Water and a travel bowl
- Your pet’s regular food and any medications
- Leash, harness, and collar with an up-to-date ID tag
- Waste bags, and a small litter tray for cats on longer trips
- A favorite blanket or toy for comfort
- Paper towels and cleaning wipes
- A copy of vaccination records
- A basic pet first aid kit
Make sure your pet is microchipped and that the contact details on the chip are current before you travel.
Plan Regular Breaks
On long trips, stop every two to three hours so your dog can drink, stretch, and go to the toilet. Always clip on the leash before opening the car door, because an excited or frightened pet can bolt into traffic. Cats are best kept in their carrier during breaks, as they can escape quickly in unfamiliar places.
Never Leave Your Pet Alone in the Car
Cars heat up quickly in warm weather, even with windows slightly open or when parked in the shade. Within minutes the temperature inside can reach dangerous levels and cause heatstroke. In cold weather, cars can also become dangerously cold. If you need to stop somewhere your pet cannot come, take them with you or travel with another person who can stay with them.

Helping Anxious Travelers
Some pets remain nervous despite gradual training. Covering a cat’s carrier with a light cloth can help it feel hidden and secure. Calm music and a steady temperature also help. For dogs, a long-lasting chew or a stuffed toy can provide distraction. If your pet becomes very distressed, speak with your veterinarian about other options.
Final Thoughts
With the right restraint, gradual practice, and a well-packed bag, car journeys can be safe and even enjoyable for your pet. Secure your pet every time, plan for breaks, and never leave them alone in a parked car. A little preparation goes a long way toward a stress-free trip.
