Why Does My Dog Bark in the Car?
A dog barking in the car is often telling you something: they may be excited, worried, carsick, frustrated by what they can see, or uncomfortable with the way they are travelling. The fix is not to shout louder. Start by making the car safer and less overwhelming, then rebuild the journey in small successful steps.
Quick Answer
Secure your dog, reduce visual stimulation, avoid long journeys while the problem is severe, and restart training with a parked car before building up to one- or two-minute drives. Barking with drooling, lip-licking, vomiting, shaking, or refusal to enter the car can point to travel sickness or fear, so speak to your vet early.
First, Rule Out Motion Sickness
PDSA lists barking or whimpering alongside shaking, reluctance to get into the car, drooling, panting, repeated swallowing, lip-licking, retching, and vomiting as possible travel-sickness or travel-fear signs. Do not assume your dog is being difficult. If these patterns repeat, your vet can help rule out medical problems and discuss appropriate treatment.
Make the Car Setup Boring and Secure
Use a properly secured carrier, travel crate, or harness so your dog is not sliding around, climbing forward, or distracting the driver. Give them a familiar non-slip surface and keep the car ventilated and cool. Do not let a dog hang their head out of a window; PDSA warns they can be injured or distract other drivers.
Restart Training in Tiny Stages
- Walk to the parked car and reward calm behaviour.
- Let your dog get in with doors open and engine off.
- Practise settling in the restraint or carrier.
- Close doors, then run the engine briefly.
- Drive for one or two minutes only when your dog is relaxed.
- Repeat successful journeys before adding a few more minutes.
If your dog starts to bark, shake, or panic, stop progressing and return to the previous easy stage. Ending before they become overwhelmed is more useful than forcing them to “get used to it.”
Plan the Journey Around Your Dog
Walk your dog before leaving, allow time for food to digest, and keep the first trips short. On longer journeys, offer water and regular lead-on toilet breaks. Pack a collapsible travel bowl, towel, and familiar blanket. Our guide to dog car seats, harnesses, and crates helps you choose a secure arrangement.
When to Call the Vet
Contact your vet if barking comes with vomiting, heavy drooling, repeated retching, panic, collapse, pain, or sudden behaviour change. PDSA advises that car sickness can worsen when it is not managed. Do not give human anti-sickness or anxiety medicines without veterinary advice.

Frequently Asked Questions
Why does my dog bark only when the car moves?
Movement can trigger nausea, fear, excitement, or frustration. Watch for other signs such as drooling, panting, shaking, or vomiting, and ask a vet for advice if it repeats.
Should I cover my dog’s crate in the car?
Some dogs settle with less visual stimulation, but ventilation and comfort must remain good. Introduce any cover at home first and do not use it if your dog becomes hotter or more distressed.
Can I use treats to stop barking in the car?
Treats can help create positive early practice sessions, but do not distract a nauseous or panicked dog. Use tiny rewards only when your dog is calm and ask a vet about recurring sickness.
How long will retraining take?
It depends on the cause and your dog. Repeat easy, calm stages for as long as needed rather than rushing to a long journey.
