The drooling starts first. Then the lip-licking, the yawning, the restless shifting on the back seat — and if you’re unlucky, the unmistakable result all over your upholstery. If that sounds familiar, you’re searching for the best anti-nausea supplements for dogs with car sickness for a very good reason.
Here’s the thing most product pages won’t tell you: car sickness has two quite different causes. In puppies, it’s usually physical — the balance structures in the inner ear are still developing, so the motion of the car genuinely makes them nauseous, and most youngsters outgrow it by around their first birthday. In adult dogs, it’s often learned anxiety: the car has come to mean feeling sick (or a trip to the vet), so nerves fire up the nausea before the engine even starts. That’s why, for an anxious adult, a patient desensitisation programme — short, happy trips that end somewhere fun — matters more than any chew. Supplements are a supporting act, not the headline.
Used in that spirit, the right supplement can genuinely help. Ginger is the traditional anti-nausea ingredient here, used for centuries to support a settled stomach and normal digestive motion. Travel-focused products pair it with calming ingredients — chamomile, valerian, L-tryptophan, sometimes melatonin — so the stomach and the stress response are both addressed. Timing matters more than brand: most of these products are designed to be given 30–60 minutes before you set off, ideally not on a completely full stomach.
We compared Amazon’s travel and calming options on named ginger content, sensible calming actives, travel-specific positioning, brand track record and buyer feedback — and narrowed it down to these five.

What to Look for in an Anti-Nausea Supplement for Car-Sick Dogs
- Ginger, named on the label: Ginger is the ingredient with the traditional anti-nausea rationale. Look for it in the active ingredients — ideally alongside peppermint or fennel — rather than buried in a vague “botanical blend”.
- Match the formula to the cause: A drooling, panicky adult needs the calming side of the formula (chamomile, valerian, L-tryptophan, L-theanine) as much as the ginger. A bright but queasy puppy mainly needs the stomach support and time to mature.
- Sensible timing instructions: Good travel products tell you when to give them — typically 30–60 minutes before departure, sometimes repeated on long journeys. Vague “feed daily” products are general calmers, not travel tools.
- Age minimums: Most melatonin- or valerian-containing chews are labelled for dogs over 12 weeks old. Check before giving anything to a very young puppy.
- Quality signals: Long-established brands, cGMP-compliant US manufacturing and clear active-ingredient panels beat flashy new listings. And trial any product on a short, low-stakes trip before the big holiday drive.
1. NaturVet Quiet Moments Plus Hemp Calming Aid — Best Overall
NaturVet has been making pet supplements since 1994, and Quiet Moments is one of Amazon’s longest-running calming lines — this hemp version sat at the top of Amazon’s Dog Relaxants category at the time of our research. Each soft chew combines ginger with melatonin, L-tryptophan and thiamine, plus hemp, and the listing is explicitly positioned for motion sickness and travel as well as storms and separation stress. That dual action is exactly what a car-sick dog needs: ginger for the stomach, calming support for the nerves feeding it.
Dosing is by weight for dogs over 12 weeks, the chews come in a resealable jar, and NaturVet manufactures in the USA in cGMP-compliant facilities. It’s the most “complete package” pick here — a proven brand, a travel-relevant formula and a large 180-count jar that suits regular travellers.
Pros: Ginger + melatonin + L-tryptophan in one chew; explicitly aimed at motion sickness; brand established in 1994; big 180-count jar.
Cons: Melatonin and hemp won’t suit every dog — check with your vet first for pregnant dogs or dogs on other medication; not for puppies under 12 weeks.
Best for: Most car-sick dogs — the balanced first choice for regular journeys.
2. Deley Naturals Dog Calming Chews — Best Organic Ginger Blend
Deley Naturals builds its formula around organic ginger root, organic chamomile and organic passion flower, backed with valerian root and L-tryptophan — and it’s one of the few calming chews whose own description talks directly about car sickness and the gassy, unsettled stomach that comes with it. If your dog’s travel problem reads as “nerves plus nausea” in roughly equal measure, this is the most on-target ingredient list in this roundup.
The chicken-flavoured soft chews are made in the USA using a no-heat process designed to protect the active ingredients, and the jar holds 120 chews. Deley suggests introducing them gradually over a couple of days before relying on them for a journey, which is sound practice for any new supplement.
Pros: Organic ginger, chamomile and passion flower; explicitly positioned for car sickness; no-heat manufacturing; 120 chews per jar.
Cons: Valerian has a distinctive smell some owners dislike; a younger brand than NaturVet, with a shorter track record.
Best for: Owners who want an organic-leaning formula built specifically around travel sickness.
3. Healthy Solutions For Pets Calming Chews — Best for Young Dogs and Frequent Short Trips
This veterinarian-formulated chew pairs ginger with melatonin, chamomile, passion flower, thiamine and L-tryptophan, and its maker recommends it for travel and motion sickness alongside storms, grooming and separation worries. It’s made in the USA in an FDA-audited, cGMP-compliant facility by a company that has been manufacturing pet supplements since 1994 — reassuring credentials in a category full of newcomers.
The formula is labelled for all breeds and for puppies over 12 weeks, and the 120-count jar works out as a practical option if you’re doing regular short trips while a young dog learns that the car isn’t a threat. As with all melatonin chews, give it 30–60 minutes before travel rather than as you’re opening the car door.
Pros: Ginger in a vet-formulated calming blend; strong manufacturing credentials; suitable from 12 weeks; generous 120-count jar.
Cons: A general-purpose calming chew rather than a travel-only specialist; melatonin may cause drowsiness, so trial it at home first.
Best for: Puppies over 12 weeks and young dogs being gently introduced to car travel.
4. HomeoPet Travel Anxiety Relief — Best Drops for Dogs Who Refuse Chews
Some dogs won’t eat a chew when they’re already stressed, and some owners simply prefer drops. HomeoPet’s Travel Anxiety is a homeopathic liquid formulated specifically for travel: the label targets drooling, panting, restlessness and vomiting associated with motion sickness, dosed starting around 45 minutes before a journey and repeatable every 15 minutes for up to three doses. It’s non-sedating, can be dropped onto the gums, in water or on a small amount of food, and one 15 ml bottle covers dogs, cats and other small pets.
We’ll be straight with you: homeopathy is contested, and the evidence for it is anecdotal rather than trial-based. That said, this listing has been on Amazon since 2007 and held a 3.8-star average across more than 800 ratings at the time of our research — a lot of owners clearly feel it takes the edge off, and it’s a gentle, low-intervention option to try before anything stronger.
Pros: Purpose-built for travel and motion sickness; non-sedating liquid suits chew-refusers and multi-pet homes; sold since 2007; easy repeat dosing on long trips.
Cons: Homeopathic — evidence is anecdotal; the base contains alcohol (tiny doses, but check the label if that concerns you); small 15 ml bottle.
Best for: Dogs who won’t take chews, and owners who want the gentlest possible first step.
5. Bocce’s Bakery Digestive Support Pumpkin Ginger Treats — Gentlest Ginger Biscuit
Sometimes the right answer is the simplest one: a plain ginger biscuit before the journey. Bocce’s Bakery is a well-known US treat brand, and its Digestive Support recipe — sold as “Bye Bye Stinkies” — is a wheat-free, soft-baked treat built on pumpkin and ginger with a short, recognisable ingredient list. A couple of these given 30–45 minutes before a short trip is the traditional ginger-biscuit approach in a tidy, dog-specific package.
Be realistic about what it is: a functional treat, not a measured supplement dose, so the ginger per biscuit is modest and there’s no calming blend behind it. For mild puppy queasiness on short hops, though, that gentle profile — plus pumpkin’s fibre for general digestive support — is often all that’s needed, and dogs genuinely enjoy them.
Pros: Simple wheat-free recipe with real pumpkin and ginger; trusted bakery brand; doubles as an everyday digestive treat; highly palatable.
Cons: Treat-strength, not a standardised supplement dose; no calming ingredients; small 6 oz bag.
Best for: Mild cases, short journeys, and puppies as part of a positive car routine.
Chews, Drops or Biscuits — and the Training That Matters More
Soft chews (NaturVet, Deley, Healthy Solutions) deliver the fullest ginger-plus-calming package and are the best bet for moderate to strong car sickness. Drops (HomeoPet) win on convenience and repeat dosing. Ginger biscuits (Bocce’s) are the gentlest option for mild cases. Whichever you choose, pair it with desensitisation: sit in the stationary car and reward calm, then engine on, then round the block, then short trips ending somewhere lovely. For an anxious adult dog, that programme — not any product on this page — is what actually fixes car sickness long-term.
Safety Notes Before You Travel
- These supplements support comfort during travel; they do not treat disease. Vomiting alongside lethargy, diarrhoea, loss of appetite or a swollen tummy — or a dog who also vomits at home — needs a vet, not a supplement: it can signal gut disease, pancreatitis, a blockage or something toxic eaten.
- Never give human travel-sickness tablets (such as dimenhydrinate or meclizine products) unless your own vet has specifically directed it and given you a dose for your dog.
- If your dog vomits despite supplements and training, tell your vet. The genuinely effective anti-emetic for canine motion sickness is a prescription medicine — maropitant (Cerenia) — and vets prescribe it for exactly this problem.
- Ask your vet before using melatonin- or valerian-containing products for pregnant or nursing dogs, puppies under 12 weeks, or dogs on sedatives, anxiety medication or with liver disease.
- Practical travel basics still apply: a small meal 3–4 hours before departure (not a full stomach, not just-fed), a window cracked for fresh air and equalised pressure, and a leg-stretch break every couple of hours.
Frequently Asked Questions
Why do puppies get car sick more than adult dogs?
In young dogs the balance structures of the inner ear are still maturing, so vehicle motion produces genuine nausea. Most puppies outgrow car sickness by about a year old — positive, short trips in the meantime help them outgrow the anxiety version too.
How long before a journey should I give an anti-nausea supplement?
Most travel chews work best given 30–60 minutes before departure so the ingredients are active before the motion starts. HomeoPet’s drops are labelled to start around 45 minutes ahead, with repeat doses every 15 minutes if needed. Always follow your product’s label.
Can I give my dog human travel-sickness tablets instead?
No — not unless your vet has specifically told you to and given a dose for your dog. Human products differ in strength and ingredients, and dosing guesswork can cause real harm. If over-the-counter pet options aren’t enough, your vet can prescribe maropitant (Cerenia), which is licensed for motion sickness in dogs.
Should I feed my dog before a car trip?
A small meal 3–4 hours before travelling is usually the sweet spot. A completely full stomach invites vomiting; a totally empty one can worsen nausea in some dogs. Keep water available, and avoid rich treats or chews right before setting off.
What if supplements don’t stop my dog being sick in the car?
Escalate kindly: a structured desensitisation programme for anxiety-driven sickness, and a vet visit. Your vet can rule out ear or gut problems and, if appropriate, prescribe a proper anti-emetic — needing one is common and nothing to feel you’ve failed at.
Our Verdict
For most dogs with car sickness, start with NaturVet Quiet Moments Plus Hemp — a proven brand, ginger plus a sensible calming blend, and a formula aimed squarely at travel. Choose Deley Naturals if you prefer organic ingredients, Healthy Solutions For Pets for a young dog and regular short trips, HomeoPet Travel Anxiety if your dog refuses chews, and Bocce’s Bakery ginger biscuits for the mildest cases. Then do the unglamorous bit that works best of all: short, happy practice trips, so the car stops meaning “sick” and starts meaning “adventure”.
