Road trips with a dog can be one of the best parts of having one — when you plan for them. Most problems on the road come down to three things: paperwork, safety in the car, and managing heat and stress. Here's how to prepare.
Before You Leave: Health and Paperwork
Each US state sets its own entry rules for pets. Most require a current rabies vaccination, and many also require a Certificate of Veterinary Inspection (CVI, or "health certificate") from a USDA-accredited vet — commonly issued within 30 days of arrival, though some states use a shorter window. Check the rules for every state you'll enter with that state's animal health office or your vet before you go, and carry paper and digital copies.
International trips are a separate process with much stricter timelines, so start planning months ahead. And make sure flea, tick and heartworm prevention is current — you may be driving into areas with different parasites than at home.
Keep Your Dog Restrained in the Car
A loose dog is a distraction while you drive and a projectile in a crash — dangerous for the dog and for everyone in the car. Use a crash-tested harness clipped to the seat belt, or a secured crate or carrier, and keep your dog in the back seat, away from front airbags. Not every "crash-tested" harness is independently verified: see our dog car harness crash-test comparison to choose one and find the right size. Skip long tethers and never attach a restraint to a collar.
Packing List
- Water and a collapsible bowl: bring enough from home — don't rely on finding clean water at rest stops.
- Food, treats and medications: pack a few extra days' worth in case of delays.
- ID: a collar tag with your cell number, and a microchip with up-to-date contact details.
- First aid basics: gauze, self-adhesive bandage, antiseptic wipes, tweezers or a tick remover, and the number of an emergency vet along your route.
- Familiar bedding: familiar smells help many dogs settle.
- Waste bags and an enzymatic cleaner: for accidents and car sickness.
- A long-lasting chew or food toy: something to occupy your dog during stops in the car with you, or once you arrive.
On the Road
Plan a break every 2–3 hours for water, a walk and a bathroom stop — more often for puppies and senior dogs. Always leash your dog before opening the car door at a rest area.
Never leave your dog alone in a parked car in warm weather — not even for a few minutes. According to the American Veterinary Medical Association, the temperature inside a car can rise about 20°F in 10 minutes and more than 40°F in an hour, so a 70°F day can mean over 110°F inside. Cracking the windows doesn't make it safe. Plan stops where your dog can come with you, or bring someone who can stay with them.
Managing Car Anxiety and Motion Sickness
If your dog is anxious in the car, start practicing weeks before the trip: sit in the parked car with the engine off, then on, then take very short drives, pairing each step with treats or meals. Build up gradually. Some dogs also do better with a pheromone spray like Adaptil on their bedding or a pressure wrap like a ThunderShirt, though results vary.
For dogs that drool, vomit or become very distressed on drives, talk to your vet before the trip — there are prescription options for motion sickness and travel anxiety. Don't give human medications without your vet's guidance.
