Some dogs hear the keys and are at the car before you are. Others plant their feet at the driveway, drool the whole way, and bring up breakfast on the back seat.
The frustrating part is that the drooling dog and the terrified dog look almost identical. Here is how to tell which you have, what helps each, and what Australian law actually requires.
Key takeaways
- Motion sickness and travel anxiety share almost every sign, including drooling, lip licking, yawning, panting and vomiting.
- They also cause each other. A dog sick once learns the car makes them feel awful, and starts dreading it before the engine turns over.
- Queensland and Victoria both state that no road rule requires a dog inside the cabin to be restrained, though a dog on your lap is an offence and a dog on a ute tray is a load.
- Middle of the back seat is the best spot, for two separate reasons.
- Never leave a dog in a parked car. In Victoria that is illegal past ten minutes at 28 degrees or above.
What we cover
1. Sickness or fear, and why it matters
Put the two lists side by side and the problem is obvious. Motion sickness, per VCA and Merck, shows up as drooling, lip licking, yawning, whining, panting, restlessness and vomiting. Stress, per VCA, shows up as drooling, lip licking, yawning, whining, pacing, panting and gastrointestinal upset including vomiting.
They are the same signs. VCA's advice is that the only way to separate them is to know your own dog and pay attention to context.
A few things lean towards fear rather than nausea. Whale eye, pinned ears, a tucked tail, trembling, refusing to get in at all. And above all, signs that appear before the car has moved.
Then there is the loop. Merck notes that fear of the vehicle becomes a contributing factor, and that dogs show signs in a stationary car. The AKC is more direct: the psychological reasons can cause the physical symptoms, and a dog whose first trips ended in vomiting learns the car means feeling terrible. VCA adds the version many Australian dogs live, where a dog who travels twice a year, both times to the vet, knows exactly what the car means.
Quick tip
- Sit in the parked car with your dog for five minutes, engine off. If they drool and pant with the car stationary, you are dealing with fear, not motion.
2. What helps motion sickness
Vets think young dogs are more prone because the balance structures of the inner ear are not fully developed, though they hedge. VCA says the reason may be, and Merck does not mention age at all. Many puppies grow out of it by around twelve months. Some never do.
On food, the sources disagree. VCA suggests withholding food for up to eight hours before travel, the AKC says twelve. Both agree water stays available, and both agree a cool, quiet, well-ventilated car helps.
The AKC also suggests cracking the windows and positioning your dog to face forward rather than watching the world blur past a side window. That one comes from the AKC alone with no veterinary source behind it, so treat it as sensible to try rather than proven.
Where there is real evidence is medication. Maropitant, sold as Cerenia, is a prescription anti-nausea drug licensed for motion sickness in dogs, lasting twenty four hours from a single dose. Some antihistamines are also used. Every source routes these through your vet, and VCA makes the point that matters most: these drugs only help with motion sickness, not anxiety.

3. Rebuilding the car from scratch
If the problem is fear, this is the fix. VCA and the AKC describe near identical ladders.
Start with your dog in the parked car, engine off, for a few minutes. Praise, treats, nothing else. Next session, start the engine and sit there. Then reverse out of the driveway and come straight back. Then once around the block. Then build towards twenty or thirty minutes.
Two rules matter more than the ladder, both VCA's. You cannot force a dog to get over this. And visible anxiety is a signal to stop for the day, because pushing through deepens the association you are trying to undo. Do not scold a dog who whines. Go back a step tomorrow.
The AKC adds the principle that makes the long term difference. Vet and grooming visits are stressful, so balance them with trips somewhere your dog likes. If nine journeys in ten end somewhere good, the tenth stops being a prediction.
One detail people miss: condition your dog to the travel setup itself, not just the car. Introduce a harness or seat in the driveway first.
4. Where your dog should sit
Middle of the back seat. Two independent lines of reasoning arrive there.
The safety one first. The AKC is clear dogs belong in the back so they are not harmed by airbags, and the AVMA notes unrestrained animals can be crushed by a deploying airbag or thrown through a windscreen. If a dog must travel in front, PetMD's vets say switch the passenger airbag off.
The nausea one second. The AKC suggests the middle of the back seat because a dog there is more likely to look forward.
The AVMA is worth quoting on why loose dogs are a driving problem, not only a dog problem. Small dogs get into footwells and interfere with the pedals. Large dogs lean across laps and block your view.
5. What Australian law actually says
This gets overstated constantly, so here is the accurate version. There is generally no road rule requiring a dog inside the cabin to be restrained. Both the Queensland Government and Transport Victoria say so explicitly on their own websites, and both recommend restraint anyway.
What is an offence is driving with an animal on your lap, and driving without proper control of your vehicle.
A dog on a ute tray or trailer is different. Queensland classes it as a load that must be restrained, and by the RSPCA's own summary every state and territory has an animal welfare provision making unrestrained transport on an open tray unlawful. Victoria is strictest, where it is also illegal to put a dog in the boot of a sedan.
Transport Victoria adds the point worth remembering inside the cabin too: there may be no road rule, but you should still consider animal cruelty laws. Penalties apply and vary by state.
Quick tip
- If you use a harness, the RSPCA notes that one safe for vehicle restraint may be a different item from the one you walk your dog in. Crash testing has repeatedly found walking harnesses failing under load.
6. What a car seat does and does not do
We sell a dog car seat, so we will be straight with you.
There is no recognised Australian crash standard for dog car restraints. RSPCA Australia says so directly, and warns that manufacturers' own testing claims deserve scrutiny. The Center for Pet Safety, the only body doing this work to a real protocol, tested four pet travel seats and found a failure in every one. They classify the category as distraction prevention rather than crash protection.
So we will not tell you a car seat protects your dog in a crash. What it genuinely does is keep a dog out of the footwell and off your lap, the risk the AVMA and the RSPCA both name, and give an anxious dog a consistent, contained, forward-facing spot. That is what the ladder in section three depends on.
A consistent spot in the back
PawRide™ Dog Car Seat
A raised, contained bed for the back seat in eight colourways, so your dog has the same predictable place every trip rather than sliding around the bench. Distraction prevention and containment, which is what the evidence supports. Not a crash protection device.

7. The parked car
Not for a minute, not with the windows down, not in the shade. RSPCA Australia states that temperatures inside a car can more than double the outside temperature on mild days, that shade and open windows do not really help, and that it can take just six minutes for an animal to die. Those are the RSPCA's own figures rather than a measured study.
The hardest Australian number is the Victorian one. It is illegal there to leave an animal unattended in a car for more than ten minutes when the outside temperature is 28 degrees or above.
Heatstroke signs from the RSPCA are relentless panting, drooling, agitation, very red or pale gums, breathing distress, vomiting and weakness. Notice that panting, drooling and vomiting appear on all three lists in this article. On a hot day, assume the worst of the three. First aid is tepid water and fanning, never ice, then a vet.

Common questions
Is it illegal to drive with an unrestrained dog in Australia?
Generally no, not inside the cabin. Queensland and Victoria both state there is no road rule requiring it, though both recommend it. A dog on your lap is an offence, and a dog on a ute tray must be restrained.
Should my dog travel in the front seat?
No. Airbag deployment makes the front the worst spot, and the back seat is also better for nausea.
Can I give my dog something for car sickness?
Talk to your vet. Maropitant is licensed for motion sickness in dogs, but dosing is weight based and human products often contain other ingredients. Anti-nausea medication does nothing for the fear side.
