Why Do Dogs Pant In the Car & How to Change It

This post may contain affiliate links. Read more here.

Traveling in the car with your happy pup’s tongue flapping around during a summer trip is a wholesome image for sure.

On the other hand, there are dog owners that couldn’t imagine five calm minutes in the car.

Their dog is panting, drooling, shivering, and just hating the overall driving experience.

Just getting around the next corner could turn the ride into a puke-filled nightmare.

This forces owners to leave their dogs at home until the next dreaded vet visit (which is the reason many dogs are afraid in the first place).

If that horror scenario seems familiar, I might just have a solution for you.

In general, panting is a natural cooling mechanism and everybody’s dog pants once in a while.

But panting can also have a different meaning and your dog may want to tell you that he’s feeling really uncomfortable and anxious or overly excited in the car.

Unfortunately, travel anxiety is common in dogs and could be caused by many things, including trauma from an accident or lack of desensitization.

Thank goodness that there are many ways to change your dog’s perception of car rides and eventually turn him into a calm and comfortable travel companion.

Let’s make sure you and your furry friend both enjoy the next adventure with some quality bonding time!

Why Do Dogs Pant in the Car?

Dogs pant in the car due to temperature, dehydration, car sickness, or because they’re afraid or excited due to a lack of exposure and proper introduction to car rides.

Panting is an essential mechanism as you’ll find out in a minute since that’s how dogs regulate their body temperature.

Dehydration is a real risk.

Car sickness is a thing in dogs too, not every individual handles it equally well.

Your dog might be expressing his discomfort of being in the car or he is just too excited to arrive at the dog park.

Let’s dive into all the reasons why your dog might be panting inside the car.


If it’s particularly hot or sunny, you might see your dog panting in the car from the get-go or on your ride back after a long walk.

Every dog’s tolerance varies and my Rottweiler usually starts panting more at 60-70 degrees Fahrenheit (16-21 degrees Celsius).

It’s characterized by a wide-open mouth (often referred to as a smile), heavy breathing, and maybe even drooling.

Dogs don’t sweat the way we do and only produce sweat on their paw pads and the nose because they are not covered with fur.

Producing moisture beneath the fur wouldn’t make much sense as it can’t escape and winds alone won’t cut it.

However, they do have glands associated with every hair follicle and release pheromones.

But those sweat glands alone could never cool down their body temperature.

Instead, they utilize the evaporation of moisture from their mouth to create a circulation of hot and cold air.

Maybe it’s simply too hot for your dog inside the car and he starts panting.

Cars can become hotter than the outside environment, a phenomenon we’ve all witnessed.

Never ever leave your dog alone in the car, especially during the spring or summer.

Temperatures can rise quickly to a life-threatening level in minutes (even in the shade).


If your dog didn’t drink in the morning or was exercised heavily on a moderately hot day, he might just need water to avoid dehydration.

A long walk in the summer or just a game of fetch can really heat up your dog’s body.

All that drooling and sweating flushes liquid out of your dog’s body.

Make sure that you always bring a portable water dispenser to keep your pet hydrated.

Car Sickness

Many dogs, like people, can get car sick which leads to excessive drooling and possibly vomiting.

Especially puppies can experience this type of motion sickness and usually grow out of it.

It definitely doesn’t build up a positive association if you feel bad every time you go on a car ride.

Medications and supplements can be carefully used to treat car sickness.

Speak to your vet for more information.

Don’t feed your dog at least one hour prior to the car ride to reduce the likelihood of him feeling sick.

Puppies and small dogs are often affected because they cannot see out the window which also worsens travel sickness in humans.

You can buy your dog an elevated car seat or provide him with the iBuddy Dog Car Seat Cover that has a see-through mesh window.

This is the one I’m using for my Rottweiler and while I had to replace it a couple of times, it does the trick.

Your dog will be able to see what is going on in front of him even when laying down, so perhaps a little less car sickness. Some dogs also get sick inside a travel crate in the car.


Travel anxiety can actually develop from motion sickness and the resulting negative associations with driving.

Even if your dog has never vomited in the car before, he still can suffer from this type of anxiety.

Shivering, pacing, restlessness, drooling, panting and peeing are all signs of anxiety that you will need to look out for.

There are several reasons to why your dog has developed travel anxiety.

From underexposure as a puppy to trauma from a car accident.

You will want to change that behavior into something positive so your dog can finally enjoy driving with you. Keep on reading for the action steps below.


A car can be a very strange environment for a dog to be in.

The engine roars loudly, cars and people pass by, and lots of new smells are coming in.

Don’t forget that a dog’s hearing ability and olfaction are way stronger than a human’s.

Turns and bumpy roads can send your dog sliding due to a lack of grip.

I would feel very insecure if I had to endure this type of transportation without even knowing what was going on.


Most dogs are stressed and pant excessively inside the car because they just haven’t been exposed or properly introduced to driving.

If you only take your dog on a trip to hell (aka the vet) every few months, he will definitely fear driving with you.

Take your companion with you on fun trips to the dog park or hiking through the woods (if your dog’s small enough, he might fit into a backpack).

Medical Reason

A dog that suddenly starts to pant excessively in the car can be a sign of pain or underlying disease.

This panting would also occur outside of the car and persist over a longer period of time.

How to Calm Your Dog Down In the Car

There are two ways that can successfully treat panting in the car:

  • Counterconditioning
  • Prevention (desensitization)

If you have only ever taken your dog to unpleasant car rides, switch up that routine and utilize a method that’s called counterconditioning.

Your dog has the perception that driving is awful so you will want to change that belief.

Start by just driving around the neighborhood and show your dog that car rides don’t have to end with a negative experience.

You can then add some trips to a playdate or just a nice day at the park.

If your dog is extremely scared or even refuses to set a paw into the vehicle, you will have to reset your training and start from zero.

In case your companion is still a puppy, it’s best to take care of a problem at the root with proper desensitization.

During the socialization phase, puppies can easily be taught to associate the car with a pleasant experience.

If your dog already experiences signs of discomfort or anxiety, training must be done very slowly and in even smaller steps compared to desensitization.

But before we get into any methods, you will probably have to gear up.

A back clip harness and elastic seat belts are must-haves if you ever want to drive your dog in the car.

Never ever attach the seat belt to your dog’s collar.

Even a small impact could cost his life.

Attaching the belt to a back clip harness is the safest way to travel.

You will also want to get a car seat cover like the one I mentioned above to keep your dog safe in the back while keeping the seats clean.

Consider putting your dog in the front seat (might work better if you have a small to medium-sized breed) to reduce nausea.

Some dogs simply can’t cope with being in the car freely at all.

Transport crates are a great way to keep your dog contained and safe at all times which adds to his level of comfort.

Provide your dog with his favorite toy or a clothing piece that has your scent on it to create a familiar and pleasant space.

You can spread out some blankets in the back seats that you usually use inside the house or get your dog a ThunderShirt.

Now that we have covered the essentials, we can move on to the training steps.

Counterconditioning and desensitization are structured very similarly with the difference that you will have to go a little slower and cut down on the luring when it comes to treating anxiety.

Counterconditioning Car Anxiety

For the following method, you will need treats, a car (obviously) and lots of patience.

To effectively treat your dog’s discomfort in the car, he should be able to approach the car on his own terms and make the conscious decision to trust it.

1. Some dogs shiver at the mere sight of the car, so you will want to start the training outside of the vehicle.

Play a round of tug of war or give your dog some basic obedience commands which will be rewarded with treats and a lot of praise.

Spend a few minutes with your dog until you feel that he is getting calmer.

Every time he approaches the car, treat him to create more positive associations with the car.

You can repeat this step a few times over the course of several days or weeks depending on your dog’s reaction.

2. The next milestone would be to open the car door without your pup freaking out.

You will use the same technique from the first step and simply reward your dog for positive behavior in the vicinity of the open door.

Keep in mind to not accidentally encourage anxious behavior when rewarding your dog.

If you sense any signs of stress and uncertainty, take a step back and give your dog more time.

3. When your dog is ready to jump into the car, capture this behavior with a command.

This gives your dog a little bit of extra assurance because he knows what is expected of him and that he will be rewarded for it.

Repeat this process of jumping out of and into the car a few times and add the command “jump” to it.

Your dog will know exactly what to do which will boost his confidence in the process.

4. Now your dog will be ready for the closed door experience.

Command him inside the car and close the door for a few seconds.

Open it and let your dog outside if he wishes to.

5. You can try getting into the driver’s seat while your dog is either sitting in the front seat or back row.

Spend a few minutes with your dog there and don’t take the training any further for a few days.

6. Once your dog feels really comfortable in his dedicated seat (properly secured), you can start the engine and get the car rolling for a few seconds.

Some dogs get startled by the engine so you can choose to just expose him to this sound for a few minutes.

Exposure therapy is often used in dogs with noise or thunder phobia.

Regularly and slowly exposing them to the sound they are afraid of, will eventually normalize the noise occurrence and the anxiety will be reduced.

7. Drive your dog around the neighborhood a few times and end it with a short walk in a familiar environment.

Gradually build up the distance and add new fun places to your dog’s daily walks.

You can take him to the dog park (and just watch the other dogs from outside if he is scared), visit a doggy friend that he adores or enjoy a calm walk through the forest.

The more often you drive him around in the car the better he will adjust to it.

If your dog is severely suffering from anxiety and the tips mentioned above didn’t help, talk to your vet on possible medications like Benadryl, Dexmedetomidine, or CBD oil.

Don’t use any meds before consulting your veterinarian.

Preventing Excessive Panting

If you just brought home a new puppy or rescue dog and want to get him accustomed to driving in the car, early desensitization will prevent anxiety.

Compared to the first training method, your puppy has no idea what a car really is so you will have to tackle this a little differently.

1. Think about where your puppy should be driving preferably for the rest of his life.

Switching up routines and rules isn’t something dogs respond well to.

Take your dog’s adult weight into consideration and crate train him prior to driving if you plan on using a crate in the car.

2. Walk a few rounds around the car and let your dog sniff out everything.

Once he is ready, pick him and place him on his seat.

Let him explore and get comfortable with the whole interior. Lots of praise and treats need to be involved!

3. Get into the driver’s seat and provide your puppy with something to chew on like a stuffed Kong.

Chewing is extremely calming to dogs, especially puppies in the teething phase.

4. While your puppy chews on the toy, turn on the engine and wait for his reaction.

If he is acting calm or completely ignoring the sound, treat him.

If you notice stress signals like lip licking, yawning, escaping, sneezing, or laid back ears, turn the engine off.

You can continue your training outside and get back to the car on another day.

Don’t force your puppy inside the car because you are in the perfect position of teaching and showing your puppy everything for the first time in a positive manner.

5. After completing the first few steps, you can take your puppy on fun little road trips.

Puppies are so easily excitable so this shouldn’t be a difficult task.

Expose him to as many places, people, and sounds as you can.

Calming an Excited Dog In the Car

Anxiety and excitement always have triggers.

Whether that’s hitting the breaks or opening the car door.

My dog used to get super excited when I turned off the engine because she knew that something awesome was about to happen.

When trying to calm your hyper dog in the car, change his expectations, and only reward calm behavior.

Now, what do I mean by this?

Go on a regular drive with your dog and before getting outside, wait for him to calm down.

Your dog expects to jump outside and sniff that amazing grass and suddenly he has to wait.

This can take many minutes and will test your patience.

Don’t interact with him in any way because negative attention is also attention.

Once your dog calms down, reward him by letting him out.

You will have to repeat this process over the course of a few days or weeks until your dog really gets it.

Be as consistent as possible so your dog can quickly learn that he will be only let outside in a calm state.

No treats or verbal praise are required as the walk will be his biggest reward.

Once you are outside, don’t stop the training.

If your dog immediately starts to pull on the leash, follow the tips outlined in my leash training guide.

Dog Suddenly Anxious & Scared In the Car

Sudden anxiety in the car can develop from a medical issue or trauma.

Sore joints can hurt a lot on bumpy roads with many turns so the pain could be the problem.

Your dog might have also experienced something traumatic like a car accident.

Loud noises from sirens or construction sites could easily trigger a fearful response.

To successfully cure the anxiety, you will need to determine the trigger and write down the exact circumstances in which the response occurs.

Afterward, follow the steps I have mentioned under counterconditioning.

Talk to a veterinarian or behaviorist in case the tips don’t work and evaluate the situation in order to develop a tailored action plan for you and your dog.

Let me know in the comments if your dog always gets excited or fearful when he’s about to enter the car!

Hi Danielle My dog a staffy cross was initially fine in the car however after a car went up the back of me at a roundabout she now shakes and pants a lot. On short journeys however to my local woods she is calmer but when we travel an hour to visit relatives she pants the whole way. Any ideas? I have tried the pheromones sprays, thunder jacket, valerian spray to no avail. I have also switched her from the boot to a hammock in the back seat but still no improvement. Any ideas appreciated, thanks. Claire


Monday 2nd of January 2023

Hey Claire, it's great that you've already tried a couple of things, but perhaps good old positive reinforcement and small steps help best, especially if something has happened to set off that fear in your Staffy cross. It's best to rule out medical issues but other than that, there's not much you can do apart from reintroducing the car slowly. Chat with your vet if you think medication for longer trips might be beneficial but I'd exercise caution when it comes to meds.

I have a two year old working kelpie I take him almost every where I go he works great on livestock He has been riding in a vehicle all his life any thing I head to he wants in or on but he pants and drools Yonns the hole time it could be minutes or hours I don’t think he’s scared but anything that moves sets him off the only way to calm him it to make him Lie down but that’s a constant battle he will lie down but not for long and I have to tell him again I know that’s in his make up kelpies are very Energetics by nature that’s why they make great livestock dogs very loyal and obedient other than riding in the truck I almost feel like I’m shortening his life with all Anxiety of riding in a vehicle What do you think


Tuesday 8th of November 2022

Hi Albert,

so even working dogs should be able to relax during their time off and but you're right in saying that energetic breeds such as Kelpies are more likely to show this behavior, especially if movement sets them off.

Has your dog been working before you bring him in the car or are you often on the way to work? Exercising your dog before may help calm him down but that could be contrary to your goal if you plan on working him after the car ride (in that case, anticipation could be the whole reaosns why he's so excited).

Whether the stress it puts on him is bearable really depends on behavior he shows. Generally, I'd check in with your vet just to be sure it's not a medical issue. Other than that, you can start at the beginning with desensitizing your dog to the car rides, positively reinforcing, etc. etc.

Hope that helps, Danielle

My Pomeranian (7years old) loved the car . He was always excited to go for a ride. Now he gets in the car excited to go but as soon as we start to move he starts panting. He keeps it up constantly until the car stops. He always travelled so well even on long trips. We always marveled at not even knowing he was in the car until we made his pee break stops. He was home without going in the car for about two weeks due to family illness. He does not seem ill or sore at all. The word car gets him very excited and entering the car is no problem but as soon as the car starts to move the panting starts. He travels in a soft sided crate and has air blowing his way constantly. I am at a loss as to what happened suddenly to cause this panting.


Tuesday 13th of September 2022

Hi Marilyn, keep in mind that a sudden shift in behavior could indicate medical issues. Considering your dog's age, they often just change and might be more sensitive to the movements of the car. It's hard to rule out the behavioral side without seeing your dog's body language, but maybe you take a look at your Pomerian's health with your vet first. With age comes more sensitivity and maybe he's just more prone to stress (even positive stress).

Cheers, Danielle

I have a 2 year old rescue dog.. She is a 45 lb black mouth cur. She wil get in the back seat without incident and I can drive around town no problem.. The moment I get on the highway/ drive over 80km she starts to pant excessively and trembles. I camp a lot and at times drive for 2 to 3 hours with her and I'm not sure how to ease her anxiety. I always make sure she has had lots of exercise and water prior to a long car ride. I've also tried the pheromone spray which did nothing.. She will not take treats or even hew anything while we are in the car so I'm not sure what to try next.. I would rather not give medications but would do that as a last choice.. Thank you


Sunday 4th of September 2022

Hi Trish,

so did your dog not like going on the highway or driving longer from the very beginning? You might have to go back and start associating the car positively when she's still receptive to treats. Pack the highest value chews or toy you have. That could help if car rides weren't introduced in baby steps or if she had negative experiences in the past. But if it's really a speed/distance issue, maybe your dog is more prone to car sickness than others.

Meds should always be the last resort, but you can consult your vet. It doesn't fix an underlying behavioral issue if there is one.

Maybe change the position. Seats folded with a bed vs backseat can make a difference. Or a crate, but not all dogs like being in one, especially if it's unfamiliar.

Hope that helps, Danielle

My yellow lab is hyperactive in the car. Is there anything besides tranquillizers that can help this? It's the same as Sarah's remarks below and even on short trips it is exhausing. He does not bark but pants loudly constantly.


Saturday 20th of August 2022

Hi Roni, the best thing to do is rewarding calm behavior and work on overall impulse control to limit the excitement. If you live in a warm area, it's not uncommon and totally normal for dogs. As long as your dog isn't extremely stressed, no need to give meds on shorter trips. Probably best to avoid long trips, or train more consistently. Meds are best only used if deemed absolutely necessary by a vet.

Cheers, Danielle
