Ginger travel tablets from the health food shops. They are magic for car sickness in dogs. Give a bit larger dose than the scaled down (for dog's weight)human dosage on packet. Safe as it's just powdered ginger in a fine chalk carrier and no horrible side effects. Can be crushed and rolled on a little bit of cheese or butter for ease of administration.
Administer 30 minutes before travel and renew dosage every 2-2.5 hours while traveling. Don't forget to re-administer 30 minutes before the home trip. Once the dogs know they are not going to be sick, they don't anticipate it and make themselves sick - problem over. I think they think themselves into it after first getting ill as little pups.
Usually only need to use the ginger tablets half a dozen trips and the sickness problem will be gone. It's magic and harmless. I've used them for 15 years on many dogs of different sizes from large working Kelpies, Labs etc., to toy breeds and now all mine are great travelers. Have recommended it to many others and only one failure reported but suspect it was not re-administered before the first home trip so efficacy had worn off. Last packet I bought were "Nature's Own" brand but they all seem to be the same.
