Start
by taking your pup on very short trips up and down the block, for
example, every day for a week.Make sure it has been 2-4
hours since your pup last ate, and avoid a route with curves.Keep the trip upbeat and happy, and follow up the excursion with
a play session, so that your pup associates the car with
something he likes.
Ignore
any vomiting.Clean it up when you get home, and try again
the next day, making a shorter trip.
When the pup shows no signs of nausea, begin increasing the
distance of the ride.Always be sure to praise your pup at
the end of the trip.
