I'm posting this on behalf of a friend who hasn't (yet) discovered the world of knowledge encompassed by Mumsnet.
She has a five month old labrador puppy who was very very sick on his first car journey - when she went to fetch him. Since then he's sick every time he's in the car even for a short time.
I was allowed to have a dog of my own when I was 7 (we already had two). Exactly the same thing happened to her and she had to go into kennels every summer holiday while the other two came with us - that made me very sad.
Has anybody got any tips for my friend?
