"Bronte" (Nahrof Solitaire) aged 5 months suffered constantly with anxiety every time we put her in the car. We tried to make it a pleasant experience by playing with her and having her favourite things in the car. Nothing worked.
I began to give her McDowell's "Travel Trauma" 1 hour before we went in the car, then again just as we were about to leave. She settled immediately and was not sick again. It worked even on Macquarie Pass a 10 km section of winding road. It did not make her drowsy even though she did sleep. I also gave her a few drops of "Rescue Remedy".
Happy Puppy!
