It sounds like she did pretty good!
When Salem was a pup he used to get sick every time we put him in the car. He outgrew it though and now he likes the car. He is a nutball though and he will stand the entire trip. The longest trip we took him on was 6 hours and he stood and paced the whole trip, but he was happy. he likes looking out the windows. And the drooling is just terrible we drape the backseats in blankets to soak up the drool.
We are taking him to NY next month which will be 10 hours, and then we are going to take him into canada from there.
