Why Does My Dog Whine and Pace in the Car?

You're doing sixty on the highway and your eyes keep going to the mirror. Left window, right window, back again. The whining started before you were out of the driveway, and there's nothing out there he could possibly be whining at.

You can't turn around, you can't pull over every five minutes, and "he'll settle down" stopped being true about three drives ago. One owner on Reddit described exactly this in a thread titled "Dog Constantly Whines and Paces in the Car." It's a common problem, and it usually has a findable cause.

The quick answer

Usually one of two things, and often both: motion sickness, which is most often seen in puppies, or dread the dog has learned to link with the car. Drooling or vomiting once the car is moving can point to motion sickness. Whining that starts before you've left the driveway is a sign of dread about the car itself.

Is it car sickness or car anxiety?

From the front seat, the two look a lot alike. VCA Animal Hospitals lists the signs of a dog in distress in the car as a dog that may "salivate, become restless, pace, whine, howl, bark, or vomit." Nausea and nerves share most of that list.

Timing is the best clue.

• It starts once the car is moving, with drooling, lip-licking or vomiting. That leans toward motion sickness. It's tied to the balance system in the inner ear, and the American Kennel Club notes it's most often seen in puppies because those structures "aren't fully developed yet."
• It starts at the car door, or in the driveway. That leans toward anxiety. The AKC describes dogs who "dread being in the car, and may whine, drool, or even vomit before you've left the driveway."
• It's both, which is common. A dog whose first few rides made him sick can start to associate the car itself with feeling sick, so the nausea comes first and the dread follows.

There's a quieter cause too. VCA points out that dogs who only ride once or twice a year, usually to the vet, often associate the car with whatever stressful thing comes after it. If every drive ends at the clinic, the whining is a reasonable prediction.

What you can do from the driver's seat

Most advice is a training plan for next month. When you're in the car right now, these are the things within reach.

• Crack the windows a few inches. The AKC says even a little fresh air can help reduce nausea, and a cool, well-ventilated car helps too.
• Change what he sees. Watching the world blur past a side window is hard on a queasy stomach. The AKC suggests the middle of the back seat, where a dog is more likely to face forward.
• Keep him secured. VCA recommends a crate or a seat belt and harness, for his safety and yours. A loose dog pacing window to window can end up in the driver's space.
• Stop if he looks like he's going to be sick. VCA notes that pulling over and taking him for a short walk may give him some temporary relief.
• Use your normal voice, and don't scold. VCA is clear that you shouldn't scold a dog who starts to howl or whine. Frustration from the front seat just adds to what he's already feeling.

It also helps to notice what sets him off. VCA lists triggers as specific as the sound of the motor, changes in driving speed, or the windshield wipers. If the whining always spikes at the on-ramp, that's useful information for the practice drives below.

Short drives that end somewhere good

This part is slow on purpose. VCA lays out the steps like this.

1. Put him in the car, start the engine, and just sit there for a few minutes.
2. Next day, back out of the driveway and come straight back. Praise and a treat.
3. Then a trip around the block.
4. Keep building until he can ride comfortably for 20 to 30 minutes.

Two rules keep it from backfiring. First, the AKC's training guide says to move on only when your dog is completely relaxed at the current step, and if he stops eating or won't play, you've gone too fast. Second, the destination matters. A drive to the park or a friend's yard teaches something different from a drive that ends at the vet. Mix in plenty of the good ones.

Expect days or weeks, not an afternoon. Some dogs get there in a few sessions. Others need longer, and pushing them usually costs you ground.

When to call the vet

If he drools heavily or vomits once the car is moving, VCA recommends checking with your veterinarian, who may be able to help with anti-nausea medication. Only your vet can say which one and what dose, and VCA notes these drugs only help with motion sickness, not anxiety. So they won't stop whining that comes from dread.

It's also worth a call if car rides used to be fine and suddenly aren't. VCA notes that some dogs have ear problems, including inner ear infections or vestibular disease, that make them more prone to nausea. And if the anxiety is severe, your vet can talk through anti-anxiety options for travel days alongside the practice drives.

If he's still vomiting hours after you're home, or diarrhea starts alongside it, the car may not be the explanation. Dog Vomiting and Diarrhea: When to Call the Vet covers how to tell a watch-at-home night from a call to the vet.

Where a calming collar fits

VCA lists pheromone products among the options for a tense traveler. Describing one pheromone collar, it adds a point that's easy to miss: the collar has to be worn at all times, not just during car travel. That's how our Calming Collar is meant to be used. It stays on between drives, with synthetic pheromones that mimic the ones a mother dog gives off, no sedation, and up to 60 days per collar.

It won't fix motion sickness, and it won't replace the short practice drives. What it can do is lower the baseline, so the practice drives start from a calmer place. It comes with our 90-day money-back guarantee, because this kind of progress takes weeks.

FAQ

Will my puppy grow out of car sickness?

Often, yes. VCA says puppies will often outgrow motion sickness by the time they are about a year old, likely because the parts of the inner ear involved in balance are still developing before then. Some dogs never fully outgrow it, which is why the dread part is worth working on early, before the car becomes the thing he's afraid of.

Should I comfort my dog when he whines in the car?

Stay calm and keep your voice normal. The part to avoid is scolding or making a big deal of it. The AKC notes that yelling will only make the stress worse. If he's clearly anxious during a practice drive, VCA treats that as the signal to stop for the day and start again another time.

Will anti-nausea medicine stop the whining?

Only if the whining comes from nausea. VCA says anti-nausea drugs only help with motion sickness, not anxiety. If he's whining before the engine starts, the practice drives are what help, and your vet can advise if he needs more support than that.
