Some dogs love the car; others drool, whine, and throw up before you've left the driveway. The good news is car sickness is one of the more fixable problems out there.
Car sickness in dogs is common, especially in puppies, and shows as drooling, whining, lip-licking, and vomiting during travel. It stems from a mix of motion and anxiety. Many dogs improve with gradual desensitization, a forward-facing secured position, and fresh air — and for dogs that still struggle, a vet can prescribe anti-nausea or calming medication to give before trips.
Motion, anxiety, or both?
Car sickness in dogs usually mixes two things: inner-ear motion sensitivity (more common in puppies, who often grow out of it) and travel anxiety (which can linger). Telling them apart helps — a dog that drools and vomits from pure motion is different from one that panics before the car even moves. Many dogs improve with gradual, positive short trips and by riding secured and forward-facing with fresh air.
When NOT to just push through — and what helps
Do not use a feed-then-drive approach (an empty-ish stomach travels better), and avoid forcing long trips on a dog that isn't ready — that's not the right build-up and it deepens the dread. For dogs that still get sick, a vet can prescribe an anti-nausea medication like Cerenia, or a calming one for the anxiety part, to give before travel. Your vet advises which and when.

Why dogs get car sick
A combination of inner-ear motion sensitivity (more common in young dogs) and travel anxiety. Many puppies grow out of the motion part, but anxiety can linger. [1]
Simple fixes
Short practice trips that build up, securing the dog facing forward, cracking a window for air, and not feeding right before travel all help.
When medication helps
For dogs that still get sick, a vet can prescribe an anti-nausea medication like Cerenia, or a calming medication for the anxiety component, to give before travel. Your vet advises on which and when.
