Dog Car Sickness: Signs, Causes, and What to Do
Car sickness can turn a five-minute drive into a problem for both dog and owner. It is not always just a sensitive stomach: motion, anxiety, and previous bad journeys can become tied together, so a dog may begin drooling or refusing the car before the engine starts.
Quick Answer
For repeated sickness, speak to your vet. Between journeys, rebuild your dog’s confidence gradually: use a secure, non-slip travel space, practise in a parked car, start with very short drives, keep the vehicle cool, and do not feed a full meal immediately before travel.
Signs Your Dog May Be Carsick
PDSA lists drooling, panting, repeated swallowing, lip-licking, retching, vomiting, barking, whimpering, shaking, toileting in the car, and refusing to get in as possible signs. Not every dog shows every sign. The useful thing is the pattern: note when it starts, how long the drive is, whether your dog has eaten, and whether it happens before movement begins.
Build Back Up in Small Steps
- Reward calm behaviour near the parked car.
- Let your dog enter with doors open and engine off.
- Practise settling in their carrier, crate, or travel harness.
- Run the engine briefly only after they are comfortable.
- Drive for one or two calm minutes, then stop.
- Repeat successful journeys before making them longer.
Do not push through panic or nausea hoping your dog will get used to it. PDSA recommends returning to the previous stage if anxiety appears. A few easy sessions can be more valuable than one long difficult trip.
Set Up the Car for Comfort and Safety
Use a suitably secured crate, carrier, or travel harness so your dog does not slide around or distract the driver. Keep the car ventilated and cool, and never leave a dog alone in a parked car. Our guide to dog car seats, harnesses, and crates can help you compare travel setups.
For a longer drive, plan lead-on toilet breaks and bring fresh water in a collapsible travel bowl. RSPCA advises giving pets regular breaks and avoiding a full stomach before travel.
Medication and Remedies
Some dogs need vet-prescribed anti-sickness medication, especially while travel training is underway. Do not use human travel-sickness medicines or internet “natural remedies” without veterinary advice. PDSA notes that herbal products are not proven to work, and the best long-term approach is often gradual positive training alongside your vet’s plan.
Call the Vet When
Contact your vet for repeated vomiting, severe drooling, panic, collapse, pain, sudden behaviour change, or a dog that cannot tolerate short journeys. Get urgent advice if your dog seems seriously unwell. Keeping a short travel diary helps your vet decide what to investigate.

Frequently Asked Questions
Should I feed my dog before a car journey?
Avoid a full meal immediately before travel. PDSA advises allowing time for food to digest; ask your vet for individual guidance if your dog is repeatedly sick.
Will my puppy grow out of car sickness?
Some puppies improve as they mature, but early travel training matters. Speak to your vet if symptoms are recurring or worsening.
Can I let my dog ride loose to make them more comfortable?
No. A loose dog can distract the driver, be injured in sudden braking, and escape when a door opens. Use a suitable secure restraint or carrier.
How often should we stop on a long drive?
Plan regular breaks based on your dog’s needs, with safe lead-on toilet opportunities and water. Keep the first longer trips conservative.
