Thanks for that Mike... It's not sickness so much as stress. Although Billy goes in the car on a daily basis and on long journeys a few times a year, he gets quite stressed unless he can sit on the back seat (which isn't safe). He's restless, pants a lot and the saliva
he can soak a couple of towels in no time. Amber just curls up and goes to sleep but I've never known Billy lie down in the car - let alone sleep! I'm going up to Scotland in my friend's van, which is equipped with crates and I've a feeling he'll probably whine and bark most of the way
