Americans love their pets. According to the American Pet Products Association (APPA), in 2021, Americans spent more than $109.6 billion on their pets. It is no wonder that many people travel by their pets, which means dogs and cats often travel by car. Unfortunately, a lot of those dogs and cats get motion sickness. As a result, the pet owner may be forced to pull over and try to calm their pet or drive home with a sick animal.
Motion sickness (or the tendency to feel nauseous and get dizzy, then vomit when moving), is not a serious condition. It is common to all humans and even more common in dogs than in humans. Dogs are very sensitive to motion, which makes them prone to this condition.
Like humans, dogs can get carsick, too. But unlike humans, they can’t pull over to the side of the road when they start feeling queasy. And while car sickness in dogs isn’t as common as some veterinary professionals claim it is, your dog will feel better if you take the time to treat its motion sickness.
Dog car sickness is something that is common for many dogs and can turn into a real problem on longer trips. The causes of dog car sickness are not entirely understood, but we do know that smaller dogs are much more likely to have a problem than larger breeds. Dogs can suffer from motion sickness too, and this can occur at any age.
When it comes to car sickness in dogs, the unfortunate reality is that your dog’s chances of suffering from motion sickness are high, regardless of the breed. In fact, a study on dog motion sickness conducted by The American Society for the Prevention of Cruelty to Animals found that roughly 90% of dogs suffer from car sickness.
One of the most overlooked consequences of a dog car ride is motion sickness. Whether on a road trip, a run to town, or just a ride from the veterinarian, motion sickness can become a major issue for pet parents and their dogs.
While human travel sickness has been studied, the causes and treatments for canine travel sickness have been under-examined until recently. If you own a dog or you are planning to get one, then you should know about the state of car sickness.
You would definitely want to treat it to be able to enjoy the trip with your dog. But most importantly, you should be aware of the symptoms and the treatment options.

What Causes Dog Car Sickness and Motion Sickness?
Dogs can experience motion sickness from conflicts between their sensory signals and the brain’s emetic (vomiting).
This means that the vestibular system of the inner ear, which is involved in balance, can conflict with the signals from your eyes. It could lead to nausea or vomiting similar to motion sickness.
Dogs can get motion sickness. Younger dogs are more likely to experience motion sickness or car sickness than older dogs. This could be because the inner ear parts that are involved in balance aren’t fully developed.
Adult dogs can become anxious and even nauseated when they travel. This is due to the lack of conditioning and the unusual stimuli that come with being in a car. Dogs who travel less than once or twice per year, usually to visit the veterinarian, aren’t used to car rides. They often associate car rides with stressful experiences.
This can cause anxiety and stress to increase, which may lead to vomiting and diarrhea. Dogs who have experienced traumatic or frightening first rides might also associate their future travel with this stressful experience.
Dogs may be predisposed to nausea by medical conditions like inner or middle ear infections, vestibular disease (a condition that affects the vestibular apparatus in the inner ear), or middle or inner ear infections. Some dogs may also be on medications that can cause vomiting and diarrhea.
This process involves many receptors, including:
- Chemoreceptor trigger zone (CRTZ)
- Histamine
- Neurokinin 1 substance P (NK1) receptors
Dogs can also get motion sickness from anxiety, fear, or previous trauma in a vehicle. Dog motion sickness can happen while traveling in any vehicle.
Because puppies are still developing their inner ear parts, they are more vulnerable than adult dogs. The good news is that motion sickness in puppies usually improves and resolves as they get older. By the age of one year, puppies will usually “outgrow” motion sickness.
Your dog will be able to travel with you more often if you help him overcome anxiety and stress.
Car sickness/motion syndrome is caused by certain movements that affect the balance center in the brain. This can be combined with anxiety/stress while traveling. Car sickness can affect older dogs as well as puppies.
Dog car sickness symptoms
People who feel nauseated often become pale or turn green when they feel their stomach upset approaching. Dogs can become sick from car sickness. This can lead to nausea, vomiting, and high-stress levels. These are signs that your dog might be suffering from motion sickness.
- Diarrhea
- Excessive drooling
- Lip licking or smacking
- Inactivity or lethargy
- Vomiting
- Whining and pacing
Stopping the car and taking your dog for a walk if you feel that your dog might vomit may temporarily help.
Medicine for Motion Sickness in Dogs
There are several pharmaceutical options available to prevent motion sickness in dogs. Two over-the-counter medications for dogs with motion sickness are
Benadryl (diphenhydramine) and Dramamine (dimenhydrinate).
Anti-sickness medication is sometimes a good short-term solution, but the best long-term solution is to help your dog stay healthy and get used to car travel so they don’t get motion sickness. Here are some medications for motion sickness dogs, the best short-term solutions for motion sickness in dogs.
Anti-nausea medication
Cerenia® (a veterinary-specific prescription medication) and dimenhydrinate (brand names: Dramamine® or Gravol®), and meclizine (brand names: Antivert® and Bonine®) are effective drugs for motion sickness in dogs.
These anti-nausea medications can prevent vomiting from a stressed pet. One dose of Cerenia lasts for 24 hours. These drugs are not effective for anxiety, but only for motion sickness.
Talk to your veterinarian to determine if these medications would be appropriate for your dog. Also, to ensure that the right dosages are being administered.
Cerenia
Cerenia (maropitant), is the FDA-approved prescription medicine for dogs suffering from vomiting due to motion sickness. It blocks the NK1 receptors at the brainstem vomiting center, which is responsible for nausea and vomiting due to motion sickness.
Cerenia is administered once daily to dogs who are at least eight weeks old. Cerenia is very effective. Only 7% of dogs vomit after being given in a study.
Meclizine
Meclizine, an antihistamine that has sedative and anti-vomiting properties, is available over-the-counter and on prescription. Drowsiness is the most common side effect. It should be taken once per day.
Dramamine and Benadryl

Benadryl (diphenhydramine), and Dramamine (dimenhydrinate) are two Over-The-Counter options for dogs suffering from motion sickness.
These antihistamines can be taken every 8 hours. They may also have sedative properties. Both Benadryl and Dramamine are antihistamines that can be given every 8 hours and may have sedative effects. Dramamine may be better tolerated given a small amount of food.
A small amount of food may make Dramamine easier to tolerate. Benadryl may cause gastrointestinal problems such as diarrhea and vomiting. One of the side effects of Benadryl is drowsiness. It has been used to help calm anxious dogs in situations like a thunderstorm. The Merck Veterinary Manual states that Benadryl, which is a similar medicine, may also relieve mild-to-moderate anxiety in pets who are traveling or experiencing motion sickness.
Benadryl is not recommended for use in combination with other products. The active ingredient should contain Benadryl (diphenhydramine).
- Using Benadryl together with Dramamine might increase side effects such as drowsiness, blurred vision, dry mouth, heat intolerance, flushing, decreased sweating, difficulty urinating, stomach cramps, constipation, heart rate irregularities, confusion, and memory problems in dogs.
- Dramamine and Benadryl are two different drugs. Dramamine is a brand name of dimenhydrinate, an antihistamine that reduces the effects of the natural chemical histamine in the body. Dramamine is used to treat or prevent nausea, vomiting, and dizziness caused by motion sickness.
Benadryl
Diphenhydramine (brand names: Benadryl, Vetadryl, Banophen, Genahist, Diphenhist, Unisom, Sominex) is an antihistamine that can be used on cats, dogs, and ferrets to treat allergies, motion sickness, and vomiting.
Benadryl can cause drowsiness in dogs, which helps calm anxious ones. According to the Merck Veterinary Manual, diphenhydramine can relieve mild-to-moderate anxiety symptoms in pets who travel. It can also relieve motion sickness.
Two to three times daily is the recommended dosing. Your veterinarian may recommend a different dose depending on your dog’s medical history or other medications. 50mg of Benadryl should be given to a 50-pound dog. It can come in two 25 mg tablets or four 12.5 mg chewable tablet forms, or 20ml of the Benadryl liquid (12.5 mg/5ml)
Dogs can be given Benadryl and Diphenhydramine quickly. It will usually take 1 to 2 hours to start working, but it can sometimes take less than an hour. The effects of Benadryl last 8 to 12 hours in dogs.
Benadryl can be used safely and effectively for dogs if it is administered according to the directions of a veterinarian. To ensure that your dog doesn’t have any adverse reactions, it is important to closely monitor them after administering any new medication.
Upper respiratory allergies can be caused by histamines in humans, but itchy skin can be caused by cytokines in dogs. Antihistamines are not effective in controlling cytokines, which cause inflammation and itching.
Your dog can be given Benadryl (diphenhydramine ) 2 to 3 times per day at 1 mg per pound . A 12-pound dog could receive 12mg. This is equivalent to half an adult dose or one children’s Benadryl. 50mg would be sufficient for a 50-pound dog, as well as two adult Benadryl. Benadryl may cause drowsiness.
Anti-Anxiety Medication
These medications should only be used in pets that are extremely stressed. Even the most anxious pet traveler can be relaxed by taking Xanax (Xanax(r),) trazodone(Desyrel(r), or any other prescribed medication, 12 hours before departure.
A majority of veterinarians recommend that you give your pet a second dose approximately two hours before you travel. To be effective, prescription medication should be taken at least a few days before you travel. Follow your doctor’s instructions.
Anti-anxiety medication and behavioral modification may be necessary if your dog experiences anxiety in the car.
Your veterinarian will be able to provide advice on safety and the best medication for your dog’s motion sickness.

Here are some natural treatments suggestions for Your Car-Sick Dog:
- A few drops of lavender oil or chamomile oil can be applied to a cotton ball. Place it in the vehicle 30 minutes before you take off. The vehicle will be filled with a relaxing aroma. Be sure to get rid of the cotton ball, so that your dog doesn’t eat it!
- Spray the car with a little Dog Appeasing Pheromone (DAP).
- To settle your dog’s stomach, homeopathic remedies like nux vomica may be used.

You should not give your dog more raw ginger than 1 teaspoon. Ginger can cause gassy, nausea, and heartburn in dogs who eat too much.
