If your dog starts shaking, panting, whining or refusing to get into the car, you are not alone. Many UK pet parents deal with dog car anxiety, especially during trips to the vet, weekend drives, holidays, or even short journeys around town.
The good news is that car anxiety is not “bad behaviour”. It is usually your dog’s way of saying they feel unsure, uncomfortable, overstimulated or unsafe. Once you understand why it happens, it becomes much easier to help your dog feel calmer on the road.
In this guide, we will look at the most common reasons dogs get anxious in the car, the signs to watch for, and practical ways to make car travel safer and more comfortable.
Common Signs of Dog Car Anxiety
Dog car anxiety can look different from one pet to another. Some dogs become very vocal, while others go quiet and tense. Common signs include:
- Shaking or trembling before or during the journey
- Panting even when the car is not hot
- Whining, barking or crying
- Excessive drooling
- Trying to climb onto your lap
- Pacing or struggling to settle
- Refusing to get into the car
- Vomiting or signs of motion sickness
- Hiding when they see car keys, harnesses or carriers
If your dog shows these behaviours regularly, it is worth treating car travel as something they need help learning, rather than something they should simply “get used to”.
Why Do Dogs Get Anxious in the Car?
1. The Car Feels Unpredictable
Cars are full of strange movement, engine noise, vibrations, road sounds, traffic, sudden stops and changing views. For a dog, especially a puppy or a nervous rescue dog, this can feel overwhelming.
Unlike humans, dogs do not automatically understand where the car is going or why the journey is happening. If every car ride feels unpredictable, your dog may start to associate the car with stress.
2. They Associate the Car With Negative Experiences
Many dogs only go in the car when something stressful is about to happen, such as a vet visit, grooming appointment, kennel stay or long journey. Over time, the car itself becomes a warning sign.
If your dog thinks “car equals vet”, they may become anxious before the journey even starts.
3. Motion Sickness Can Create Fear
Some dogs feel physically sick in the car, especially puppies and younger dogs. If a dog feels nauseous during travel, they may begin to fear car journeys because they expect to feel unwell again.
Signs of motion sickness can include drooling, lip licking, yawning, restlessness and vomiting. The PDSA has helpful advice on car sickness and motion sickness in dogs.
4. They Do Not Feel Secure
A dog that slides around on the back seat, stands on the centre console, or tries to move between passengers may not feel safe. Even if they seem excited, lack of stability can increase stress.
Creating a calm, contained travel space can help. For some dogs, this may be a secure car seat area. For smaller pets, a familiar carrier can create a den-like space that feels more predictable.
5. They Have Not Been Introduced to Car Travel Gradually
Car confidence takes practice. If a dog’s first few journeys are long, noisy or stressful, they may not build positive associations. Short, calm introductions are often more effective than expecting a dog to handle a long journey straight away.
How to Help a Dog Feel Calmer in the Car
Start With the Car Parked
Before planning a real journey, let your dog spend time near the parked car. Reward calm behaviour with treats, praise or a favourite toy. Then let them sit inside the car without turning the engine on.
The goal is simple: teach your dog that the car is not always a stressful place.
Take Short Practice Trips
Begin with very short journeys. A two-minute drive around the block can be more useful than one long trip that overwhelms your dog. Gradually increase the journey length as they become more relaxed.
Create a Familiar Travel Space
Dogs often settle better when they have a consistent place to sit. A familiar blanket, soft base, or secure travel setup can help them understand where they are meant to be.
If your dog is small, nervous or prefers enclosed spaces, a comfortable pet carrier may help them feel more protected. You can explore ZoePaws’ pet carrier bags for everyday outings, vet visits and short journeys.
For dogs who travel on the seat, a dedicated travel area can help reduce sliding, movement and mess. ZoePaws’ pet car seats are designed for more comfortable car journeys with pets.
Avoid Feeding Right Before Travel
If your dog is prone to motion sickness, avoid giving a large meal immediately before a car journey. A lighter stomach may help reduce nausea. If sickness happens often, speak to your vet for tailored advice.
Keep the Car Cool and Well Ventilated
Heat can make anxiety and sickness worse. Never leave your dog alone in a hot car. The RSPCA warns that cars can become dangerous very quickly in warm weather, even when it does not feel extremely hot outside. You can read their guidance on dogs in hot cars.
Use Calm, Predictable Routines
Dogs notice patterns. If every journey starts with rushing, loud voices and last-minute stress, your dog may become anxious before you even leave home.
Try creating a simple travel routine:
- Prepare the car before bringing your dog out
- Use the same seat, carrier or travel space each time
- Reward calm behaviour before the engine starts
- Keep early trips short and positive
- End some journeys somewhere enjoyable, such as a park
Is It Safe for a Dog to Move Around Freely in the Car?
In the UK, dogs should not be allowed to freely move around the vehicle in a way that could distract the driver or cause injury during sudden braking. The PDSA recommends using suitable restraints such as a pet seat belt, carrier or dog guard when travelling with pets. You can read more in their guide to safe car travel for pets.
Even if your dog is calm, an unsecured pet can become a distraction. A more stable travel setup is not just about comfort. It can also support safer journeys for both pets and people.
When Should You Speak to a Vet?
If your dog vomits regularly, becomes extremely distressed, panics before every journey, or shows sudden anxiety that did not happen before, speak to your vet. There may be a medical reason, motion sickness, pain, or a deeper anxiety issue that needs professional support.
You should also ask your vet before using calming supplements, medication or travel aids, especially for puppies, senior dogs or dogs with existing health conditions.
What Should You Pack for a Calmer Car Journey?
A simple travel setup can make a big difference. For short trips, consider packing:
- A secure carrier, travel seat or restraint
- A familiar blanket or soft mat
- Water and a travel bowl
- Poo bags and wipes
- A favourite toy or chew
- Treats for rewarding calm behaviour
- A towel for muddy paws or rainy UK walks

Final Thoughts
Dog car anxiety is common, but it can often be improved with patience, gradual training and a more comfortable travel setup. The aim is not to force your dog to “be brave”. The aim is to help them feel secure enough to relax.
Start small, keep journeys positive, and give your dog a consistent space in the car. Over time, many dogs can learn that car travel does not have to be scary.
