# Car Sickness in Dogs: What to Do on the Next Ride and When to Call the Vet

By [Cal Hewitt](https://dogserv.com/authors/calvin-hewitt/) · Published October 10, 2026

Car sickness in dogs shows up as drooling, yawning, lip licking, whining, pacing and vomiting, and it comes from the inner-ear balance system, from travel anxiety, or from both. For the next ride, skip a big meal right before you leave, secure your dog in the back seat, keep the car cool, stop for breaks, and ask your vet whether an anti-nausea or anxiety medicine makes sense.

Please don't give human medicine or ginger until your vet says so. If your dog is also vomiting outside the car, I'd call the vet, and I know how stressful it is to dread the ride to the groomer, the boarding kennel or the vet's office.

### Key takeaways

- Drooling, yawning, lip licking, whining, pacing and vomiting are the usual signs of car sickness in dogs.
- Motion sickness comes from the inner-ear balance system, and travel anxiety can start before the car even moves.
- Before the next ride, avoid a large meal right before travel, secure your dog, keep the car cool and plan breaks.
- Ask your vet before giving Benadryl, Dramamine, meclizine, ginger or any calming supplement. No dose should be copied from a human label.
- Vomiting outside the car, persistent vomiting, a sudden change in an older dog, or head tilt, wobbling or falling needs a vet's evaluation.
- Collapse, severe trouble breathing, suspected poisoning, heat illness, or repeated vomiting with weakness needs an emergency clinic now.

## What can I do before and during the next ride?

Most of the help comes from small changes you can make today. The [ASPCA](https://www.aspca.org/news/how-enjoy-safe-and-fun-trip-with-your-pet), [AAHA](https://www.aaha.org/resources/the-ultimate-guide-to-traveling-safely-with-your-pet/0/) and [VCA Animal Hospitals](https://vcahospitals.com/county-west/know-your-pet/motion-sickness-in-dogs) all point to the same basics.

Before you leave:

- Skip a large meal right before the ride. The right timing varies by dog, so ask your vet for instructions that fit yours. The [ASPCA](https://www.aspca.org/news/traveling-pets-follow-these-expert-dos-and-donts-keep-them-safe) describes feeding three or four hours before departure.
- Put your dog in the back seat, in a properly engineered restraint (more on that in a later section).
- Pack water, a leash, cleanup supplies and a familiar blanket or something that smells like home.
- Plan stops for longer trips.

On the road:

- Keep the car cool and well ventilated. Cool air through the car is fine; letting your dog hang its head out the window is not, because the [AVMA](https://ebusiness.avma.org/files/productdownloads/traveling_brochure.pdf) warns that debris can injure the eyes, ears and nose.
- Watch for early signs, and pull over if your dog is getting distressed or looks like it's about to vomit.
- At a safe stop, offer a short, controlled walk and some water.
- Stay calm and don't scold. Scolding adds stress, and stress adds to nausea.
- Never leave your dog alone in a closed vehicle.

If your dog has been sick on every ride, tell your vet before the trip. That gives you time to talk about medicine instead of making a guess on the way out the door.

## Which signs fit car sickness?

The [Merck Veterinary Manual](https://www.merckvetmanual.com/dog-owners/brain-spinal-cord-and-nerve-disorders-of-dogs/motion-sickness-in-dogs) and VCA describe a pattern that often builds before vomiting. Watch for:

- Heavy drooling
- Yawning
- Lip smacking or licking
- Whining
- Pacing or restlessness
- Uneasiness
- Lethargy or sitting very still
- [Diarrhea](https://dogserv.com/dog-diarrhea/)
- Vomiting

Some dogs have reduced appetite for several hours afterward. Drooling and lip licking are worth learning, because they often come first. If you catch them early, you can pull over before your dog vomits, which is kinder for your dog and a lot easier on your back seat.

Lip licking, pacing and whining are also stress signals, so our guide to [dog body language](https://dogserv.com/dog-body-language/) can help you read what else your dog is saying in the car.

## Is it motion sickness, travel anxiety, or both?

Motion sickness is physical. Motion sets the inner-ear balance organ off, and it connects to the part of the brainstem that triggers vomiting. Your dog's eyes, body and ears send mismatched signals about movement, and nausea follows.

Travel anxiety is emotional. A dog may become anxious about the restraint, the engine noise, the movement or an unfamiliar place, or may link the car with the vet, the groomer or a kennel. VCA and Merck both note that anxiety can start while the car is still parked.

A rough pattern helps:

- Signs that appear once the car is moving and ease after it stops lean toward motion sickness. Drooling, lip licking, nausea, vomiting and lethargy fit this.
- Distress that starts when your dog sees the car, gets in, is restrained, hears the engine or sits in a parked car leans toward anxiety. Panting, pacing, whining, trembling and restlessness fit this.

Here's the honest part: you can't reliably sort this out at home. The two overlap. A dog can get nauseated, learn to fear the car, and then feel more nausea because of the fear. Anxiety alone can cause nausea, vomiting and diarrhea, and some dogs have both problems.

That matters because the fixes differ. Anti-nausea treatment is a conversation for your vet, along with travel management. Anxiety needs gradual behavior work and, when your vet judges it appropriate, an anxiety medicine. Treating the nausea alone may not fix the fear, and treating the fear alone may not stop the vomiting. For a broader look at anxiety around being left, see our guide to [dog separation anxiety](https://dogserv.com/dog-separation-anxiety/), though car anxiety is its own trigger.

## When should I pull over, call the vet, or go to an emergency clinic?

**Pull over** when your dog is drooling heavily, retching, panting hard, or showing escalating distress. Let your dog out on a leash at a safe spot, offer water and let things settle before you go on.

**Call your vet soon** (book a visit, don't wait for the next trip) for any of these, according to VCA and Merck:

- Vomiting that also happens outside the car
- Vomiting that keeps going, or a dog who can't keep water down
- A sudden new change in an older dog
- Head tilt, wobbling, falling or circling
- Signs of ear pain or an ear infection
- Symptoms that don't ease when the vehicle stops

Middle or inner-ear disease and vestibular disease can cause nausea, so car vomiting isn't always plain motion sickness. Our guides to [dog ear infections](https://dogserv.com/dog-ear-infections/) and [ataxia in dogs](https://dogserv.com/ataxia-in-dogs/) cover those balance problems, and [dog vomiting](https://dogserv.com/dog-vomiting/) covers vomiting that isn't tied to the car. For a sudden change in an older dog, see our [senior dog care](https://dogserv.com/senior-dog-care/) guide.

**Go to an emergency clinic now** for collapse, severe trouble breathing, suspected poisoning, heat illness, repeated vomiting with weakness, or a serious injury. Call ahead if you can. The [DogServ directory](https://dogserv.com/directory/) lists emergency and primary-care vets by city, so you can find a clinic and its phone number before you drive.

## Will my dog grow out of it, and why are puppies and some older dogs affected?

Many puppies do get better. Puppies are more prone because the inner-ear structures that handle balance are still developing. VCA says puppies often outgrow motion sickness by about one year of age. That's a tendency, not a promise.

Adult dogs can be affected too. A dog with little car experience may feel overwhelmed by the sights and movement. A dog who had one frightening ride, or who only goes in the car for the vet, can build a bad association. Medical causes also show up, including a middle or inner-ear infection, vestibular disease or a medication side effect.

So, if your puppy gets sick on every ride, you can work on the training steps below and mention it at the next checkup. If an adult dog's car sickness is new, keeps going, or shows up suddenly in a senior dog, that's a reason to see the vet rather than wait for it to pass. Early, pleasant car experiences also help, and our plan to [socialize a puppy](https://dogserv.com/how-to-socialize-your-puppy/) covers gradual, positive exposure.

## What might a veterinarian prescribe?

For motion sickness, the main prescription option is maropitant. The [FDA](https://www.fda.gov/animal-veterinary/cvm-updates/fda-approves-first-generic-maropitant-citrate-tablets-use-dogs-prevent-vomiting) says maropitant citrate tablets are approved for preventing acute vomiting and vomiting due to motion sickness in dogs. It's an anti-nausea medicine, and it's available by prescription because a vet needs to decide whether it suits your dog. Cerenia is the brand name you may have heard.

Travel anxiety is a separate problem. When behavior work alone isn't enough, a vet may consider anxiety medicines such as gabapentin or trazodone. That's the vet's call, not a plan for an owner to pick. Our article on [gabapentin for dogs](https://dogserv.com/gabapentin-for-dogs/) explains that drug on its own.

Anti-nausea medicine and anxiety medicine treat different things. Sedation isn't a fix for motion sickness, and it doesn't tell you whether nausea, fear or both are the cause. That's why an exam and a conversation come first.

Give the vet some useful details: when the signs begin (parked or moving), how long the ride is, whether your dog vomits at other times, and what your dog eats and when. Ask the clinic for the costs of the exam and any medicine before you go, since fees vary by region and clinic.

## Benadryl, Dramamine, meclizine and ginger: what do vets say, and why ask first?

I know these are the things many of us have in the cabinet. Veterinary sources, including the [Merck Veterinary Manual](https://www.merckvetmanual.com/nervous-system/motion-sickness/motion-sickness-in-animals), describe antihistamines such as diphenhydramine (Benadryl), dimenhydrinate (Dramamine) and meclizine as options a veterinarian may consider for motion sickness. Effects can include sedation and less drooling.

Here's why I won't give you an amount, and why you shouldn't copy one from a human label: the right product, the ingredients, other medicines your dog takes, your dog's health conditions and the suitability of the drug all differ from dog to dog. These medicines aren't interchangeable. So, the next step is a call to your vet, who tells you which product, if any, and how to use it. Our article on [Benadryl for dogs](https://dogserv.com/benadryl-for-dogs/) covers that drug separately, and it isn't automatic car-sickness advice.

Ginger gets the same answer. VCA lists ginger among natural remedies, but it still tells owners to consult a veterinarian before using medicines or supplements. Support for ginger is limited, so please don't treat it as a proven replacement for veterinary care, and ask your vet before you try it.

## What can calming treats, pheromones and supplements really do?

I wish I could point you to a treat that fixes this, but the evidence doesn't back that up. Calming treats are products, not a medical category, and they don't replace a vet's assessment or behavior work.

- **Dog-appeasing pheromones.** Controlled studies have looked at them in stressful vet-clinic and fear situations, and some dogs may benefit. The results are situation-specific, and they don't show that a pheromone product prevents physical motion sickness.
- **Alpha-casozepine.** A [Veterinary Evidence review](https://www.ivis.org/library/veterinary-evidence/veterinary-evidence-vol-2-n%C2%B03-sept-2017/alpha-casozepine-efficacious-at-reducing-anxiety-dogs) found no evidence of a quick calming effect within minutes to a few days. It described the longer-term evidence as limited and weak.
- **L-theanine and other natural ingredients.** A [review of canine behavior and fear research](https://pmc.ncbi.nlm.nih.gov/articles/PMC10705068/) says many natural products lack high-quality evidence. They may be discussed as extras, not guaranteed treatments.

Ask your vet before any supplement, especially if your dog takes other medicine, has a health condition, or is a puppy, a senior or pregnant. Marketing on a package isn't proof.

## How do I train a better car ride?

If the car itself worries your dog, slow practice helps. VCA describes a gradual build, and the idea is to stop before your dog gets upset and move at your dog's pace. Go back a step if distress appears.

1.  Practice relaxing on a mat or [in the crate at home](https://dogserv.com/crate-training/).
2.  Let your dog check out the parked car with the engine off.
3.  Reward calm behavior, then end the session on a good note.
4.  Repeat until getting into the car is easy.
5.  Sit in the secured car with the engine off.
6.  Start the engine briefly, then turn it off before your dog gets upset.
7.  Back out and come back.
8.  Drive around the block.
9.  Go somewhere pleasant, like a park, not just the vet.
10.  Slowly lengthen the ride, going back a step if distress returns.

If your dog panics before the engine even starts, stay at the early steps, like sitting in the parked car, for as long as needed. When you can't spare weeks before a trip, talk to your vet about the plan for that ride. For hands-on help with fear, you can look up a trainer in the [DogServ directory](https://dogserv.com/directory/).

## How should I secure my dog in the car?

A loose dog can distract the driver and be hurt in a crash, so the [AVMA](https://ebusiness.avma.org/files/productdownloads/traveling_brochure.pdf) says dogs shouldn't ride in the front passenger seat with an airbag, should never sit on the driver's lap, and should be secured with a harness or other travel gear. The ASPCA recommends a crate or a pet seat belt.

The [Center for Pet Safety](https://centerforpetsafety.org/cargo-area-connection-advisory/) goes a step further. It recommends independently certified harnesses, crates or carriers whenever possible, checking that cargo anchors are strong enough, and using strength-rated anchor straps for crates. Its [crate study](https://centerforpetsafety.org/2015-crate-study-results/) showed that ordinary wire crates and some restraint systems can fail in crashes, so a "crash-tested" label on its own doesn't tell you much.

It also warns against extension tethers and zipline-style products, so I'd skip them. For a dog who gets carsick, a secure spot in the back seat keeps your dog from sliding around and keeps you focused on the road.

## Questions about dog car sickness

Short answers to the questions owners ask most about car rides.

### Will a dog grow out of car sickness?

Many puppies improve as the inner-ear balance system matures, often by about one year of age. Not every dog does, and an adult dog with ongoing or new symptoms needs a vet's guidance.

### Does gabapentin help with car sickness?

Gabapentin is an anxiety medicine a vet may choose when travel anxiety is part of the problem, and it doesn't treat nausea by itself. Only your vet can decide whether it fits your dog.

### Can ginger help my dog with car sickness?

Support for ginger is limited, so it shouldn't stand in for veterinary care. Ask your vet before you use it.

### Is there a natural calmer for car rides?

Evidence for natural calmers and calming treats is weak or mixed, and none is a sure fix. Pheromones show some situation-specific results, but they haven't been shown to stop physical motion sickness. Ask your vet first.

### What medication can my vet prescribe for car sickness?

Maropitant is an FDA-approved prescription option for preventing vomiting due to motion sickness in dogs. For anxiety, a vet may consider medicines like gabapentin or trazodone.

### Will Benadryl help a dog with car sickness?

Vets describe antihistamines like diphenhydramine as options for some dogs, but the product and amount are your vet's decision. Ask first, and don't copy a dose from a human label.

Your next step is simple. Write down when your dog's signs begin and how long the ride was, plan a small meal well before you leave, and call your vet about the next trip, or find a clinic near you in the [DogServ directory](https://dogserv.com/directory/).
