Car sickness

[LakeFlyPie]

We're fostering an 8ish month old rescue dog whose chances of being adoptable would increase if we can solve his car sickness. He recently travelled from Europe in a truck so presume there's a lot of stress attached to the motion for him.
He can manage 5 min journey to local park for walk but has vomited on other longer journeys so far.
He's reluctant to get into car so has to be lifted into back seat. Obviously rewards with food treats isn't an option.
Are frequent short journeys associated with a nice walk the right way to go?
Any other tips gratefully received.

Talk to your vet about cerenia tablets in most dogs using it twice on longish journeys cures the travel sickness for good.

All positive associations with the car will help, as will as many really short trips as possible.

I would probably go right back to the start -
day 1 sit in the car, close the doors, get out again
Day 2 get in the car, turn on the engine without moving, get out again
Day 3 drive 2mins, come home again
Day 4 drive 3 mins, come home again
Etc.
I've also found an Adaptil collar helped a lot for this.

Mine outgrew it by about a year. He still is very vocal ( whines) in the car before a walk though. Longest weve taken him in the car is about 1 hour.

Thanks for the advice. Had a successful short trip yesterday and he climbed in of his own volition. Small steps
