How to tell if my dog has motion sickness

These are 5 signs that would indicate that your dog has motion sickness.


Most dogs who have motion sickness are very dizzy. This will cause them to vomit. Vomiting can also be a sign that there is something else wrong with your dog. If your dog continues to vomit, it would be best for your vet to see your dog to make sure that this vomiting is just caused from motion sickness.


If your dog is very nauseated or has been vomiting, they will drool. This is one of the first signs that you will notice in your dog is that they are drooling after every car ride.  When you take your dog on a car you will commonly see that there is excessive saliva in their mouth.

While some dog breeds do drool all the time, this amount of drooling would be excessive even for those breeds that are notorious for drool.


While you may not notice vomiting or drool, your dog may have mild motion sickness and just whine every time you go for a car ride. Dogs can be uncomfortable and not settled on a car ride due to their motion sickness or dizziness causing them to whine the whole time.

The first time you take your dog for a car ride, they will need some time to get used to being in the car and riding. This can take a little time, but your dog should quickly adapt to these car trips if taken on them enough to no longer whine on the ride.

Lip Smacking

Lips smacking is often seen right before your dog starts to drool and vomit. This is your dog’s way of trying to calm their stomach and prevent them from vomiting. This is usually a good indicator that your dog is nauseated and car sick.


Being motion sick can make your dog lethargic. They are spending excess energy to try to prevent them from vomiting and maybe even vomiting. This all can cause your dog to feel bad and be lethargic.

Many of these are also signs of other diseases, if your dog is perfectly normal and only shows these signs after a car ride, they most likely have motion sickness. Your vet can fully examine your dog to see why they are showing the signs and start them on medication to help them feel much better.
