If your dog shakes and pants every time they get in the car, you’re not alone. While some dogs love car rides, others experience intense stress, motion sickness, or even pain that can make every trip uncomfortable—for them and for you.
We outline the common causes of dog shaking and panting in the car, what you can do at home, and when to seek veterinary help.
Dog Shaking and Panting in Car — Why It Happens
Dogs shake and pant in the car due to fear, anxiety, motion sickness, or physical discomfort. Some dogs associate car rides with negative experiences like vet visits, while others struggle with balance, nausea, or being confined in a moving space. These reactions are more than just nerves—they reflect real distress.
Common Causes of Dog Shaking and Panting in Car
Motion Sickness
Just like humans, dogs can get carsick.
This is especially common in puppies or dogs not used to travel.
Symptoms include panting, drooling, restlessness, trembling, and even vomiting.
Even if your dog doesn’t vomit, the nausea alone can cause intense discomfort.
Over time, the association with the car can create an anxiety loop, making symptoms worse even before movement begins.
Travel Anxiety or Phobia
Some dogs become extremely anxious during car rides, especially if they weren’t properly acclimated to traveling when younger.
Shaking, panting, whining, pacing, and trying to escape the vehicle are common signs.
For many, the car is associated with scary destinations like the vet or grooming salon.
In other cases, the noise, vibrations, and confinement trigger stress responses.
Without intervention, anxiety can worsen with each trip.
Pain or Discomfort
Older dogs or those with joint pain or arthritis may feel physically uncomfortable in a moving vehicle.
The motion can jostle sore joints or strain tense muscles, especially if the car lacks proper support.
This can lead to panting and shaking from discomfort, not just emotional distress.
Orthopedic issues, past injuries, or even an ill-fitting travel harness may contribute.

Poor Ventilation or Overheating
If the car is too warm or lacks airflow, dogs may pant to cool down.
Dogs don’t sweat like humans and rely on panting to regulate temperature.
Combine heat with anxiety, and symptoms can escalate quickly.
Always check for signs of heat stress—rapid breathing, bright red gums, or lethargy—in addition to shaking.
Negative Associations
If your dog only rides in the car to go to the vet, boarder, or groomer, they may learn to expect unpleasant outcomes.
This can result in anticipatory stress before even starting the engine.
You might notice your dog starts shaking as soon as you grab your keys or open the car door.
Over time, this behavioral conditioning builds fear even if the actual ride is uneventful.
What to Do If Your Dog Is Shaking and Panting in Car
Start by making the car a more positive experience. Begin with short, pleasant rides that don’t end in a stressful location.
Use treats, praise, and favorite toys to associate the car with comfort and rewards.
Secure your dog safely in a well-padded crate or car harness to improve stability and reduce fear.
Keep the car cool, quiet, and free of strong odors. Crack windows slightly for ventilation.
If symptoms persist, talk to your vet about anti-nausea or anti-anxiety medications.
When to Call or Visit Your Vet
Consult your veterinarian if your dog:
Vomits frequently during or after rides
Refuses to enter the car
Becomes increasingly distressed over time
Has signs of pain or orthopedic issues
Pants or shakes even during short, easy drives
A professional exam can help determine if your dog’s symptoms stem from anxiety, illness, or something else.

Key Takeaway
If your dog is shaking and panting in the car, it’s likely due to fear, motion sickness, or physical discomfort.
You can often reduce these symptoms by training, using travel aids, or seeking veterinary help to manage nausea or anxiety.
With patience and the right support, car rides can become less stressful—and even enjoyable—for both of you.
