Thanks for your advice. I've done all that, but he continues to stress. Crating, blankets over the crate, walking at rest stops, water. He refuses all of it. Like I said before, he's spent long hours in the car since I got him at 5 months old. It's nothing new. I listen to audio books, so I can't imagine that would be stressing him, it's not heavy metal cranking through the speakers.
