I said no because I have leather seats and I can just wipe it down. Brutus sits like a nice young man while in the car and Frankie travels in a crate in the back of my explorer. He was never taught car manners and no matter what I try, I can't break him of his craziness. I really think he is happier and more relaxed in his crate anyway. Now, if you asked about doggie slobber on the car windows, that would be another story.
