Motion Sickness in Dogs

My dog gets sick when we travel. What causes this?

Motion sickness in dogs is a common problem. Motion or car sickness is more common in younger dogs than in adults. The reason may be that the parts of the inner ear involved in balance are not fully developed. Puppies will often outgrow motion sickness by the time they are about 1 year old.

Many adult dogs become anxious or even nauseous during travel due to a lack of conditioning and the overwhelming, unusual stimuli associated with moving inside a vehicle. Dogs that travel only once or twice a year (typically when visiting the veterinarian) are not used to car rides and often associate the car ride with the stressful experience that follows.

This association causes heightened anxiety and stress and may result in vomiting and diarrhea. Puppies that experience traumatic or frightening first rides may also associate future travel with that stressful event. Some dogs may have medical conditions such as middle or inner ear infections or vestibular disease (disease of the vestibular apparatus, located in the inner ear) that predispose them to nausea. Others may be taking medication that can cause vomiting or diarrhea.

How can I tell if my dog is getting motion sickness?

Nauseous humans often “turn green” or pale when they feel an upset stomach approaching. Signs your dog may be experiencing motion sickness include:

If you think your dog is going to vomit, stopping the car and taking him for a walk may help temporarily relieve his stress.

How can I prevent motion sickness in my dog?

Desensitizing or counter-conditioning your dog to car travel may take some work, but it can be accomplished. Helping your dog overcome the stress and anxiety of travel will mean that they can accompany you on trips more frequently and will allow you to spend more time together.

The best way to ease your dog’s travel anxiety is by taking several short trips before embarking on a long haul. Start by simply placing your dog in your car, starting the motor, and sitting there without moving for a few minutes. The next day, repeat this process, but back out of your driveway and then return. Be sure to praise your dog and offer a food reward for good behavior. Next, try a trip around the block. Gradually work your way up to riding comfortably for 20 to 30 minutes.

Conditioning your dog to ride comfortably in the car may require several days or even weeks. Be sure to gradually expose your nervous pet to more and more challenging stimuli. You cannot force your dog to “get over” or “deal with” his anxiety. Traveling in a confined space in a motor vehicle can be frightening for a dog and requires time to adjust.

Make sure you maintain a calm and cool attitude, and do not scold your dog if he begins to howl or whine. Visible anxiety is a sign to stop the current training and start again another day. Continuing to expose your dog to a stressful situation will only cause them to further associate the car with displeasure and fear and cause setbacks in your training.

Here are additional tips to make your dog’s travel more enjoyable and reduce motion sickness:

If your dog seems to need a little more help to stay calm during travel, talk to your veterinarian about using one of the following remedies:

Keep in mind that some prescription medications need to be started several days to a couple of weeks before travel to be most effective. Always follow instructions from your veterinarian carefully.
